86d3195518 Bootloader cleanup (UNTESTED!)
- Clean up bootloader asm
- Remove fromflash.c - it's not worth doing in C, do it in ASM
- Clean up linker script
- Force use of symbol inside bootphase2 (otherwise linker
  garbage-collects it)
- Link bootloader with gcc instead of ld

15c4dc5ace Clean up line endings, switch everything to LF instead of CRLF
Doing this for bootrom and armsrc for now. If you're using Windows,
please configure your editor for LF line endings.

8fcbf652da New bootrom
+ Add common area at end of RAM to communicate between main os and bootrom
+ Lower stack end to make room for common area
+ Implement CMD_DEVICE_INFO in both OS and bootrom to give information about the current state and supported features
+ Allow hands-free firmware update: When CMD_START_FLASH is received over USB in OS mode, the device will reset and enter the bootrom
  Pressing the button in hands-free update mode takes precedence: releasing the button will immediately abort firmware update and 
  perform a reset. Do not press the button.
+ Require each flash sequence to be preceded by a CMD_START_FLASH to set up the boundaries for the following flash sequence
  Not compatible with linux flasher before SVN revision 200
  Currently no compatible flasher for Windows. WINDOWS USERS: DO NOT UPDATE YOUR BOOTROM YET
+ Protect bootrom flash area unless magic unlock sequence is given in CMD_START_FLASH

e3ae025783 Eradicate all occurences of hardcoded memory addresses from all sources files, except for the FPGA bitstream fallback 2009-08-31 14:52:59 +00:00

4271e82d56 Only re-compile version.c as often as necessary
Make bootrom version information pointer a proper symbol (with hacky ld strangeness workaround)

8a6aec16d8 Implement version information storage and retrieval for the bootrom and the osimage.
Use perl to create the version information (thereby re-creating the perl dependency and adding an svn dependency) but fall back in case of missing perl or svn

2bfed17db2 Add a common linker script with the memory map for the complete project
Use the correct physical addresses in the memory map, and instead translate the addresses during postprocessing with objcopy

8652988d62 Merge linker scripts in bootrom to have a single linker script for the bootloader proper (previously known as bootrom-merged.s19)
Remove the now unnecessary files (merge-srec.pl, ldscript-ram-jtag)
Note that this drops the dependency on perl for bootrom build, so end-users who don't touch the FPGA bitstream will not need perl anymore

6658905f18 Initial commit for the firmware. Used the 20090306_ela version as baseline.
It is identical to the popular 20081211, with the doob addition (20090301), a
linux client, and two additional commands for LF analysis. Let me know if
you find issues here!
