Cleaned up all uses of INTERNAL_FLASH_START_ADDRESS. There was only one genuine use of this macro, all other places were using it only as a necessary compensation. While this was fine as long as it was the first meg of flash which was mapped, it became incorrect and quite dangerous whenever this assumption did not hold (such as when running from the second slot in an OTA scenario). The flash API now uses actual addresses, not translated/mapped addresses, and the users of this API have been adjusted accordingly. This makes the flash API work correctly regardless of what flash mapping is in use. The old macro is still available under the new name INTERNAL_FLASH_MAPPED_ADDRESS, and this is used to detect flash writes where the source is mapped flash (and thus has to be bounced), and to adjust the _flash_used_end linker symbol when used with flassh_find_sector() by the filesystem code. The latter usage is not OTA-proof, but in an OTA scenario the filesystem needs a fixed location anyway and thus would not use this code path. 2015-12-03 02:03:22 +01:00			`#define INTERNAL_FLASH_MAPPED_ADDRESS 0x40200000`
