* Add support to specify global build defines and options
A script manages the use of a file with a unique name, like
`SketchName.ino.globals.h`, in the Sketch source directory to provide compiler
command-line options (build options) and sketch global defines. The build
option data is encapsulated in a unique "C" comment block and extracted into
the build tree during prebuild.

Rely on argpaser for checking that all arguments are present.
Removed redundant argument check in main().
Added '--debug' option and print_dbg method.
Rethink failures on overrides. Remove well know path fallbacks,
error exit when override file is missing.
In well-known path search for preferences.txt, do not assume true.
Make failure to find an error exit event.
When Windows has two preferences.txt files and they have different
values for caching and globals.h is used, error exit. It is not
possible to know from the script which is being used.
* Use quotes on build.opt
Update comment

run_CI_locall.sh works fine locally. Hosted Multi-VM CI fails
to work with 'aggressive caching' workaround method.
Add #if defined(CORE_MOCK) to failing example.
* Try HOST_MOCK
* CI adjustments
mkbuildoptglobals.py is optimized around the Arduino IDE 1.x
behaviour. One way the CI differs from the Arduino IDE is in the
handling of core and caching core. With the Arduino IDE, each sketch
has a private copy of core and contributes to a core cache. With the
CI, there is one shared copy of core for all sketches. When global
options are used, the shared copy of core and cache are removed before
and after the build.
* Doc update
* Fix VM Address mask
Adjust VM Address mask to allow up to 8M Byte parts.
Allow for free heap size values over 64K
ESP.getHeapStats(, uint32_t,)
uint32_t getMaxFreeBlockSize();
* Fix example
* Update MockEsp.cpp for uint32_t on EspClass::getMaxFreeBlockSize()
* Added comment about heap size limitation and static_assert to verify.
Updated boards.txt to show correct External memory size and Heap size.
esp_yield() now also calls esp_schedule(), original esp_yield() function renamed to esp_suspend().
Don't use delay(0) in the Core internals, libraries and examples. Use yield() when the code is
supposed to be called from CONT, use esp_yield() when the code can be called from either CONT or SYS.
Clean-up esp_yield() and esp_schedule() declarations across the code and use coredecls.h instead.
Implement helper functions for libraries that were previously using esp_yield(), esp_schedule() and
esp_delay() directly to wait for certain SYS context tasks to complete. Correctly use esp_delay()
for timeouts, make sure scheduled functions have a chance to run (e.g. LwIP_Ethernet uses recurrent)

These changes are needed to address bugs that can emerge with the improved optimization from the GCC 10.3 compiler.
Updated performance inline functions `mmu_get_uint8()`, ... and `mmu_set_uint8()`, ... to comply with strict-aliasing rules.
Without this change, stale data may be referenced. This issue was revealed in discussions on https://github.com/esp8266/Arduino/issues/8261#issue-963529268
Changes to avoid over-optimization of 32-bit wide transfers from IRAM, turning into 8-bit or 16-bit transfers by the new GCC 10.3 compiler. This has been a reoccurring/tricky problem for me with the new compiler.
So far referencing the 32-bit value loaded by way of an Extended ASM R/W output register has stopped the compiler from optimizing down to an 8-bit or 16-bit transfer.
Example:
```cpp
uint32_t val;
__builtin_memcpy(&val, v32, sizeof(uint32_t));
asm volatile ("" :"+r"(val)); // inject 32-bit dependency
...
```
Updated example `irammem.ino`
* do a simple test of compliance to strict-aliasing rules
* For `mmu_get_uint8()`, added tests to evaluate if 32-bit wide transfers were converted to an 8-bit transfer.
When reading from a `Stream`, like `File`, using a temporary buffer is counterproductive because it complexifies the code and increases memory usage.
It's also a source of confusion because it can create dangling pointers in the `JsonDocument`.
The only benefit of using a buffer is the reading speed, but I don't think speed is the focus in this example; if it were, it would use a buffer in `saveConfig()` too.
* Fix PRxxx printf format macros
Update toolchain (newlib) to supply proper definitions for PRxxx macros.
Fixes#8220
Added a PRxxx macro to an example to ensure CI will catch any problem like
this in the future.
* Recover the BearSSL crash stack before the Heap is initialized and zeros it.
* Added comments for hwdt_pre_sdk_init()
* Keep Basic ASM version of app_entry_redefinable and removed alternate "C"/Extended ASM version. Update comments.
* Improved example HwdtStackDump to use StackThunk
* BREAKING - "i2s.h" removed, I2S library added
An "i2S.h" header was present in prior cores, but this conflicts with the
Arduino standard I2S.h header for the I2S class under Windows (because of
case insensitivity).
Initial 3.0.0 release has a redirect "i2s.h" file in the cores directory to
redirect to the "I2S.h" file in the library, but under Windows this resulted
in the IDE not building the I2S library and link errors.
Remove the offending header. Code will need to mode to including "I2S.h"
instead (which will include both the Arduino class as well as the low-level
definitions).
Fixes#8107
* Update examples to use proper I2S.h version
* wifi: remove pseudo-modes for shutdown
make shutdown and resumeFromShutdown public
removes extra code from the mode handler and include method description
in the docs
* typo
* dup
* typos
* reference only shutdown() & resumeFromShutdown()
prefer to have some specific function, don't simply chain into sleep
update examples and docs
* safeguard raw sdk config usage

* fix doc per review
* Hardware WDT Stack Dump
This Sketch demonstrates the use of a tool to print a stack dump
at reboot after a Hardware WDT event.
The module hwdt_app_entry.cpp writes a stack dump to the serial interface
after a Hardware Watchdog Timer has struck and a new boot cycle has begun.
The sketch must properly initialized the Serial port before the crash.
hwdt_app_entry.cpp is the core file that does the work.
* Corrected Style. Improved HWDT reset detectionat boot.
* Style and typos
* Update comments.
* Improvements to reset reason determination.
Improved comments.
Added option to match the UART speed used by the sketch.
Added option to print greeting at the start to indicate the HWDT stack dump code is active.
Isolated logic for handling strings: one assuming they are not inited at
the time the code is running and one that does. The later appears to be the case.
* Style plus
Fix issue with HWDT reason detection when sketch crashes too fast.
Added sample sketch menu option for crashing with a function defined
with a weak attribute via prototype, but never actually defined in
full function form. eg. `void trouble(void){return;}`
* Moved all configuration options to the top.
Adjusted configuration option order for most likely to be used to the top.
Tried to improve comments.
Replace numbers with enum values.
* Removed clutter of having an alternate printing method.
Regular global strings have worked reliably.
Tweaked reset reason detection.
Reordered elements in global structure.

data problem that occurs when printing after a flash upload using esptool.
Curiously, esptool stub also uses similar delays.
Word choices and description improvements.
* Finished TODO looked at assembly of app_entry_redefinable to confirm
no mixed up stack frame was created. Also removed no longer needed
extra level of function calling.
Use existing macros from uart_register,h to handle getting current
UART speed. Added some missing `const`.
* Comment changes.
Added a few newlines to printing.
Decreased the settling delay after the uart_div_modify call.
* Improved comments.
Print caution message when stack integrity checks failed.
* Several corrections to set_uart_speed
Comment improvements
Added missing ";"
* Removed unused include.
Code cleanup.
Comments.
* Now runs from flash before SDK is started.
Cache_Read_Enable working. Free 1K of IRAM and 200 bytes of DRAM.
* Changed ICACHE size from 32K to 16K to avoid conflict with
SDK or core selecting smaller 16K ICACHE.
The Issue: Cache_Read_Enable does not clear the bit field when mapping IRAM to
ICACHE on register 0x3FF00024. Thus, no problem upgrading from 16K to 32K;
however, you cannot downgrade from 32K to 16K. These bits are cleared at boot.
Improved uart data rate change handling.
Update comments.
* Added support to print ThunkStack.
Adjustments to inline asm. Added "memory" when callx0 is used.

* Corrected new errors from upgrade to GCC 10.1 toolchain related to
constexpr and casting integers to pointers.
Cleared warning for asm.
* Work around divide by 0 HWDT event under toolchain 10.1.
* Changes to move feature into core.
Making ready for selection via tools menu, updated defines to DEBUG_ESP_,,, format.
Added HWDT and HWDT_NO4KEXTRA options to boards.txt.py. These options are selectable
from Arduino IDE 'Tools->Debug Level'
Converted macro names that use to be constexprs to uppercase.
Update comments. Added comments to maintainers anotated by '//C'
Revised example.
* Fix stack character buffer length.
* Updated comment to reflect support via Arduino IDE Tools menu.
* Improve meshing of HWDT and NOEXTRA4K
* Made compatible with `disable_extra4k_at_link_time()` usage.
Changed to strings containing "no4kextra" to "noextra4k" to be consistant with
original usage.
Updated example to provide indications of which build options were used or resulted.
Some comment cleanup.
* CI style
* Adjusted down the ROM Stack space for the extra 4K Heap option.
If too large, a really bad crashes occurs.
Updated the example to start WiFi. This helps double check ROM
Stack space size is not too small at start.
Removed stale comment.
Changed cont stack check functions to make globally available.
* Add replacement aes_unwrap for the debug HWDT option.
Improves the SYS stack space available when using the extra 4K Heap
option in conjunction with HWDT. Replaces the ROM AES buffer at
0x3FFFEA80 with one provided by malloc().
* Update umm_info_safe_printf_P to support default of unaligned PROGMEM strings.
* Improve cont stack trace for yielding case.
Check if cont stack is yielding to SYS, use g_pcont->sp_yield to limit the
amount of the cont stack dumped.
Generalized dev logic path to create a generalized debug function hwdt_pre_sdk_init_icache.
* Added missed update to heap.cpp for change to use PSTR instead of PSTR4
* Updated comments and #if in aes_unwrap.
* Update boards.txt
Provides a transparently accessible additional block of RAM of 128K to
8MB by using an external SPI SRAM. This memory is managed using the UMM
memory manager and can be used by the core as if it were internal RAM
(albeit much slower to read or write).
The use case would be for things which are quite large but not
particularly frequently used or compute intensive. For example, the SSL
buffers of 16K++ are a good fit for this, as are the contents of Strings
(both to avoid main heap fragmentation as well as allowing Strings of
>30KB).
A fully associative LRU cache is used to limit the SPI bus bottleneck,
and background writeback is supported.
Uses a define in boards.txt to enable. If this value is not defined,
then the entire VM routines should not be linked in to user apps
so there should be no space penalty w/o it.
UMM `malloc` and `new` are modified to support internal and external
heap regions. By default, everything comes from the standard heap, but
a call to `ESP.setExternalHeap()` before the allocation (followed by a
call to `ESP.resetHeap()` will make the allocation come from external
RAM. See the `virtualmem.ino` example for use.
If there is no external RAM installed, the `setExternalHeap` call is a
no-op.
The String and BearSSL libraries have been modified to use this external
RAM automatically.
Theory of Operation:
The Xtensa core generates a hardware exception (unrelated to C++
exceptions) when an address that's defined as invalid for load or store.
The XTOS ROM routines capture the machine state and call a standard C
exception handler routine (or the default one which resets the system).
We hook into this exception callback and decode the EXCVADDR (the
address being accessed) and use the exception PC to read out the
faulting instruction. We decode that instruction and simulate it's
behavior (i.e. either loading or storing some data to a
register/external memory) and then return to the calling application.
We use the hardware SPI interface to talk to an external SRAM/PSRAM,
and implement a simple cache to minimize the amount of times we need
to go out over the (slow) SPI bus. The SPI is set up in a DIO mode
which uses no more pins than normal SPI, but provides for ~2X faster
transfers. SIO mode is also supported.
NOTE: This works fine for processor accesses, but cannot be used by
any of the peripherals' DMA. For that, we'd need a real MMU.
Hardware Configuration (only use 3.3V compatible SRAMs!):
SPI byte-addressible SRAM/PSRAM: 23LC1024 or smaller
CS -> GPIO15
SCK -> GPIO14
MOSI -> GPIO13
MISO -> GPIO12
(note these are GPIO numbers, not the Arduino Dxx pin names. Refer
to your ESP8266 board schematic for the mapping of GPIO to pin.)
Higher density PSRAM (ESP-PSRAM64H/etc.) should work as well, but
I'm still waiting on my chips so haven't done any testing. Biggest
concern is their command set and functionality in DIO mode. If DIO
mode isn't supported, then a fallback to SIO is possible.
This PR originated with code from @pvvx's esp8266web server at
https://github.com/pvvx/esp8266web (licensed in the public domain)
but doesn't resemble it much any more. Thanks, @pvvx!
Keep a list of the last 8 lines in RAM (~.5KB of RAM) and use that to
speed up things like memcpys and other operations where the source and
destination addresses are inside VM RAM.
A custom set of SPI routines is used in the VM system for speed and code
size (and because the core cannot be dependent on a library).
Because UMM manages RAM in 8 byte chunks, attempting to manage the
entire 1M available space on a 1M PSRAM causes the block IDs to
overflow, crashing things at some point. Limit the UMM allocation to
only 256K in this case. The remaining space can manually be assigned to
buffers/etc. managed by the application, not malloc()/free().
Improve resume speed by passing in last known BSSID
Provide a simpler example for WIFI_SHUTDOWN/WIFI_RESUME
Add documentation for WIFI_SHUTDOWN and WIFI_RESUME.
* Allow specifying waveform generator in source code
Allows code to explicitly specify which waveform generator it wants,
without needing to use one of the 100 IDE menus or adding a `-D`
compile-time define.
Uses weakrefs to allow for apps to call `enablePhaseLockedWaveform();`
within their `setup()` (or anywhere, really) and have the phase locked
versions override the default waveform generators automatically.
For example:
````
void setup() {
// Uncomment following line to use phase-locked waveform generator
// enablePhaseLockedWaveform();
Serial.begin(115200);
pinMode(LED_BUILTIN, OUTPUT); // Initialize the LED_BUILTIN pin as an output
analogWriteRange(1000);
}
void loop() {
analogWrite(LED_BUILTIN, 100);
delay(1000); // Wait for a second
analogWrite(LED_BUILTIN, 900);
delay(2000); // Wait for two seconds (to demonstrate the active low LED)
}
````
Also adds an example showing it's use.
Address @dok-net's comments and also remove the _weak/_bound version of
startWaveform() since it's invariant of the actual waveform generator.
Make verify fail more visible.
Updated example irammem.info to show performance and test int16 handling
when IRAM is used.
Removed 4K performance test. It didn't show any new information over the 1K test.
* PoC cache configuration control

with its function. Improved crash reporting path.
* Style and MMU_SEC_HEAP corrections.
* Improved asm register usage.
Added some inline functions to aid in byte and short access to iRAM.
* only byte read has been tested
Updated .ld file to work better with platform.io; however, I am still
missing some steps, so platformio will still fail.
* Interesting glitch in boards.txt after github merge. A new board in
master was missing new additions added by boards.txt.py in the PR.
Which the CI flags when it rebuilds boards.txt.
* Support for 2nd Heap, excess IRAM, through umm_malloc.
Adapted changes to umm_malloc, Esp.cpp, StackThunk.cpp,
WiFiClientSecureBearSSL.cpp, and virtualmem.ino to irammem.ino from
@earlephilhower PR #6994.
Reworked umm_malloc to use context pointers instead of copy context.
umm_malloc now supports allocations from IRAM. Added class
HeapSelectIram, ... to aid in selecting alternate heaps,
modeled after class InterruptLock.
Restrict alloc request from ISRs to DRAM.
Never ending improvements to debug printing.

Several fixes and improvements to example MMU48K.
With the improved optimization in toolchain 10.1 The example divide by 0
exception was failing with a HWDT event instead of its exception handler.
The compiler saw the obscured divide by 0 and replaced it with a break point.

* Deprecate SPIFFS, move examples to LittleFS
SPIFFS has been a great filesystem, but it has significant problems in
many cases (and it's also pretty slow). Development seems to have
slowed/stopped on the upstream version, and we're not able to provide
support or fix the known issues with it as-is.
Deprecate SPIFFS variable.
Update all examples to use LittleFS instead of SPIFFS.
Also, minor cleanup on very old examples which has obsolete delays
waiting for the Serial port to come up, or which were stuck at 9600 baud
because of their ancient AVR heritage.

but excluding any filesystems) in all images in unused space in the
bootloader block.
Add a call, ESP.checkFlashCRC() which returns false if the calculated
CRC doesn't match the one stored in the image (i.e. flash corruption).
Fixes#4165
* Add example that corrupts itself, comments
Show CRC checking catch a 1-bit error in program code by corrupting a
large array, and then return it to clean and verify the CRC matches once
again.
Add comments to the CRC check routine
Clean up pylint complaints on crc32bin.py
* Check linker script for CRC space in bootsector
Add an assertion in the eboot linker file to guarantee that we have at
least 8 bytes of unused space at the end of the boot sector to patch in
the CRC. If not, the eboot link will fail.
* Add note about what to do if CRC check fails
Per discussion with @d-a-v.
When the CRC check fails, you could *try* to do certain things (but may
not succeed since there is known flash corruption at that point). List
a few ideas for application authors.
* Only single, flash/ram friendly crc32() function
* Combine the CRC calc and bin generation in 1 step
Per discussion w/@mcspr, combine the CRC calculation with the binary
generation, removing the additional build step.
This change expands the NTP-TZ-DST example to list the active
SNTP servers. It lists the IP address server name (if used) and
reachability in ntpq style octal format.
Tests:
- Build against all LwIP stack configurations and correct
operation with a single SNTP server
- Vary connectivity to an SNTP server and check reachability
updates
- Configure 3 SNTP servers by name
- With a patched LwIP stack that supports simultaneous DHCP
and DHCPv6 SNTP servers check that all server details are
listed and update correctly during operation
This removes definitions relating to the built-in SNTP client that
are LwIP v1 specific. Instead of duplicating these pull in the
LwIP header that correspond to the required functions depending on
the version of the stack being used.
Without this fix calls to sntp_getserver() work but return invalid
data and can lead to stack exhaustion.
Update the NTP-TZ-DST example to use the Arduino sntp.h header
rather than duplicate the conditional checks to use the LwIP header.
Tests:
- Build against a simple SNTP API demonstratin app and all
LwIP configurations. Verify that the app runs for an extended
period and that the expected results are obtained.
