24-02-2006 Ewout Boks. Adapted from AT91SAM7S64-RAM.ld script by M. Thomas.
- Changed the memory sections to model the AT91SAM7S256 .
- tested succesfully with AT91SAM7 GPIO Example and PEEDI debugger
on AT91SAM7S-EK equipped with AT91SAM7S256
20-08-2006 Harald Welte
- Add support for USB DFU handling
- Partition FLASH into two sections
idx 0x00000 ... 0x01fff: dfu loader
idx 0x02000 ... 0x020ff: dfu_api function pointers
idx 0x02100 ... 0x40000: application program
