e335ca2846 Reclaim more than 19K of ARM flash memory.
- added compiler options -fdata-sections and -ffunction-sections (thanks to iceman for the hint)
- removed float operations from common/lfdemod.c to avoid adding float libraries to the ARM os image
- moved the fpga images to the data section to avoid reserving unused space for a separate section

7cc204bff8 THIS REQUIRES A BOOTROM UPDATE!! To save FPGA area, split the LF and HF bitstreams and load them on-demand. 2014-06-20 01:02:59 +02:00

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

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

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
