* Move the spi vendor list from Esp.h to its own header in eboot.
* Fix ifdef issue with spi_vendors.h
* Add initFlashQuirks() for any chip specific flash initialization.
Called from user_init().
* namespace experimental for initFlashQuirks()
* Slow down flash access during eboot firmware copy
Part 1 - still some work to do
* Slow down flash access during eboot firmware copy on XMC chips
Part 2 - Identify the chip type.
Note: there may still be issues with the access speed change.
This is very much experimental.
* Commit eboot.elf

* TZ update
Added the possibility to set the timezone without using NTP. This is helpful to have the timezone advantages when using an external RTC.
* Update time.cpp
Fix/clarify comments.
Fix redundancies in Tone, end Tone waveform on exact period limit for proper sound.
Fix redundancies in wiring_pwmExtend Servo to map in-use pins, Tone already has this.
* Allow waveforms to be specified in clock cycles
Allow the PWM to specify sub-microsecond waveform edges, as have been
proposed by @dok-net and me. No other changes intended.
This will increase the linearity at 30 and 40 kHZ PWM rates, but leave
most other things unaffected.
* Cycle-accurate wafveform to specify Tone periods

* At least the F_CPU define in host mock.h is needed by host Arduino.h - need to include Arduino.h further down in mock.h for this to work.
* Geting the include order right
* Prepare for runtime CPU clock rate selection
* Fix compile for not defined F_CPU
If defined F_CPU, make getCpuFreqMHz() a constexpr
* Use defines for register CPU2X instead of hex value
* Fix build for host - getCpuFreqMHz there was also in conflict with getCycleCount, using F_CPU:
tests/host/common/mock.h:#define F_CPU 80000000 (!)
* Asymmetrical includes and defines on host
* Support restart switch from 160MHz to 80MHz, e.g for OTA. Fixes#579
* Pull GPIO initialization into its own 'weak' function.
By pulling GPIO init into its own weak function, it can be overridden by the user. This is important in cases when GPIOs should not toggle during reboot, exceptions or other crashes. Fixes#7041.
* Add prototype for resetPins()
* Use 2nd stack for update signature verification
Fixes#7145
When doing a signed update, the signature calculation can use a lot of
stack, so move it silently to the BearSSL second stack.
Also fix a memory leak of signature-bytes found by @JiriBilek
* Reset state on any error condition in Updater::end
* Add fileCreation/getCreation create-time accessors
For SDFS and LittleFS, enable a creation time accessor for files and Dir
iterators, similar to the existing fileTime/getLastWrite calls.
Remove spurious Dir::getLastWrite method (the proper and only documented
way is really Dir::fileTime).
Update json to point to new mklittlefs which copies the creation date of
files to the image.
Fixes#6992
* Remove malloc(), use stack vars for temp names
LFS filenames are limited in size and generally very small. Use a stack
variable instead of a dynamic allocation when performing full-path
computations.
* Replace "Creation" w/"CreationTime" in FS accessor
Per review, `getCreation` -> `getCreationTime`, `fileCreation` ->
`fileCreationTime`.
The names `fileTime()` and `getLastWrite()` are inherited from ESP32
implementation and unchanged.
* Add creation time to listfiles SD example
* Enable SdFat's sateTime callback for timestamping
SdFat requries the dateTimeCallback call (global for everything) to
update dates and times on created files.
Because the callback signature doesn't have space for us to provide
any parameters, we cannot get the the File, Dir, or FS object's
dateTimeCB member. Instead, just go with `time(null)` as the callback
function which is right in all but the most esoteric cases.
* Correct DOS year/month offset in dateTime callback
* Fix docs to match new xxxCreationTime() API names

* configTime(tzsec,dstsec,): fix UTC/local management
This PR also remove dead code since probably newlib updates
The NTP-TZ-DST example is also updated
* restore sntp_set_timezone_in_seconds()
fixes#6678
* +configTzTime()
Fixes#7043
Two slightly different custom routines were implemented by hand in
dtostrf (an AVR-lib non-ISO function) and Print. This resulted in
inconsistent output of float/double vars when rounding was needed.
Replace them all with a call to sprintf(), removing the duplicated, not
quite correct code.
Print(String(float)) and Print(float) now generate the same output.
* Code size optimisation of ESP.getResetReason()
doing if/else snakes for something that is a switch/case
is wasteful, as it repeatedly evaluates the same if() condition.
Also repeating strcpy_P is adding code bloat.
This simplification reduces size from 111 to 41 bytes.
* add break statement also to default case
This function has excessively long datastrings that can
better be stored in flash, reducing runtime memory footprint.
Also detailed formatting only makes sense when there is an
exception or a watchdog. In other cases instead of printing
an unhelpful "flag: 0" we can just return the ResetReason, which
is much more readable.
Saves about 120 bytes of (data) memory.
* Fix Updater potential overflow, add host tests
Fixes#4674
The Updater class could, when exactly 4K bytes were in the buffer but
not yet written to flash, allow overwriting data written to it beyond
the passed-in size parameter.
Fix per @jason-but's suggestion, and add a host test (plus minor changes
to Updater code to support host testing).
* Add missed mock file
* Remove most testing ifdefs fro updater
Per @mcspr's suggestion, we can pass in fake link symbols allowing
Updater to take the address of `_FS_start`/etc. even when building on
the host for testing.
There is still a single remaining wifi_set_power_mode ifdef'd and a
duplication of the digitalWrite/pinMode for testing vs. host building.

Only minor updates to headers and no functionality change on the
portions that we use in the ESP8266.
@Teddyz reported random crashes while running against a local MQTT
server and was able to report stack usages of up to 6136 bytes.
Increase the SSL stack to a little more than that, once again.
* change bus clock (busywait) to be programmable [issue 2524], remove unused slave STOP function
* change bus clock (busywait) to be programmable [issue 2524], remove unused slave STOP function
* change bus clock (busywait) to be programmable [issue 2524], remove unused slave STOP function
* correct for underflow < 233Hz
* change bus clock (busywait) to be programmable [issue 2524], convert tabs to spaces
* updated minimum I2C speed for calculated bus clock
Use the proper api (::clear(), isEmpty()) instead of doing
comparisons/assignments of empty strings. Also fix mixture
of tabs and spaces in the source code.
* Add a CRC32 over progmem and ESP.checkFlashCRC
Automatically embed a CRC32 of the program memory (including bootloader
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.
* Allow GZIP compressed flash updates
Modified the bootloader to be able to take stored updates in compressed
GZIP format (i.e. the output of "gzip -9 xxx.bin") and decompress them
on-the-fly to their final destination. This can work for apps and for
filesystems (when used with the 2-step update option).
Allow eboot to be built using -Os/2 optimizations by fixing some portions
which failed when any optimizations were used. Add -Wall and use data
and function sections to reduce size. Use -Os to minimize size.
Remove obsolete esptool-ck calls to build a .ROM image, we don't use it.
Move all uninitted variables to RAM from IRAM, allowing 8-bit access.
Hook in @d-a-v and @pfalcon's uzlib port to actually do the
decompression. Do not use any CRC checking which saves space. Since we
have overwritten all of flash by the time we know id the CRC matches,
there's nothing we could have done anyway.
Adjust the Updater class to support GZIP files and not attempt to patch
them.
Bootloader builds to 0xd90 out of 0xfff bytes.
* Add @d-a-v's patch for httpupdate
https://github.com/esp8266/Arduino/pull/6820#pullrequestreview-326541014
* Update uzlib to point to pfalcon++
For now, because there are some self-test failures with @d-a-v's esp8266
branch (whose cool new features we don't actually use in eboot now)
start with pfalcon's 2.9 release and add the 2 patches (clcidx to code
from IRAM/RODATA, and the Windows test file renaming) needed to build
and run successfully.
* Add (c) notice for uzlib to README
* change to make inline helpers truly inline [issue 6875]
* pulled the inline helpers out of the TWI class [issue 6875]
* removed some inlines causing issues [issue 6875]
* removed 2 more inlines from slave timeout section [issue 6875]
* removed 2 more inline attributes on public functions, moved twi_scl_valley up into the master section [issue 6875]
Fixes#6524
Should help with speed of output when printing large flash strings to
things like a file or a TCP connection.
Use a 128 byte chunk in a temp buffer to send data using write(),
reducing the # of write calls by ~128x.
Fixes#6880
The updater was patching in the proper flashmode configuration byte for
all uploads, apps and filesystems. This ended up corrupting one byte on
every FS upload.
Change updated to only patch theflashmode if it is doing an app.
