Merge pull request #375 from dlitz/for-upstream/add-nodate 
Add NODATE=1 option to Makefile, for deterministic compilation.

2407e34276 Add NODATE=1 option to Makefile, for deterministic compilation. 
There's already code that checks for NODATE in optiboot.c, so this just
passes the macro definition to the compiler and updates "make help".

Merge pull request #341 from ondrej-stanek-ozobot/fix_lockfuse_write

d54168317a Fix lock fuse verification step in the ISP target 
The fuse bits value has to be prefixed with `0x`, otherwise,
avrdude treats it as a filename and the lock fuse write fails.

be65a28adb Custom linker script. 
Implement a hack to derive section start addresses from the
information like FLASHEND that is present in the source code (via
io.h) This requires a custom linker script that uses symbols defined
by inline ASM in the C program, the inline ASM itself, and some
calculations/guesswork to figure out bootloader size for those
VIRTUAL_BOOT platforms that have a bootloader size larger than 512
bytes but significantly smaller than 1024 bytes.

c9bbfb2e37 Add an AS7-style project with more of the Eval boards defined as targets. 
(Previous AS support was for v6.x)
This is a single "solution" with multiple "projects" for each board.

0dd4cedfbd Move the rs485 tx_disable to the end of putch instead of getch, because TXCIF is annoying :-(

963abd0282 Automatically change section start address of app for BIGBOOT. 
add labels for clearer "size" output;
run size on the .hex file as well, to show just the bootloader size.

bcc71438fe Changes to allow pins_rs485.h to be used with both mega0/xTiny chips as well as older AVRs (PORTx vs VPORTx stuff.) 
Also adjust the build info included in the BIGBOOT image.

f4fd294e38 add SOFTRX=pin and SOFTTX=pin options to allow the pins to be selected when using SOFT_UART=1 
pin_defs.h was getting large and ugly, so split out the SOFTRX/SOFTRX/RS485 into separate .h files

d4077582ce refactor the MCUSR handling to make code more readable. 
The conditional compilation is moved and changed to define APP Start reasons and WDTRF Clear reasons, leaving the actual code much more straightforward.
(The assorted binaries remain the same.)

4782909e30 Add NO_START_APP_ON_POR and START_APP_ON_EXTR support from ATTinyCore. 
(with makefile aliases "BOOT_ON_POR" and "APP_ON_EXTR")
(binaries for ATmega328 with these options come out identical to ATTinyCore.)

64bda3d518 Bring the buildable attiny targets up-to-date WRT Spence Konde's ATTinyCore. 
This fixes the makefiles, expands makeall.tiny.sh, and a small warning generated by optiboot.c.

It does NOT add the other features/fixes from ATTinyCore (like RS485, or NO_START_APP_ON_POR), yet.
