/*
-----------------------------------------------------------------------------
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

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

/* AT91SAM7S256 has 256k Flash and 64k RAM */
ADD: added a compiling flag -DHAS_512_FLASH i common/Makefile.common, to be used for PM3 devices with 512KB. Original commit from @hewitt

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
