* cleanup, added volatile storage space at the end of flash memorymeri2007-04-101-3/+3

* - we increase the DFU size from 4k to 16k size. This is mainly due to thelaforge2006-09-221-1/+1
| | | | | | | | | | | | | | | | | | | SAM7S128 and SAM7S256 being restricted to 16k lock region size. If we want to lock the bootloader, it has to be 16k aligned. This wastes a lot of memory, since a non-debug DFU implementation fits currently into less than 4k. But anyway, we have lots of flexibility for the future given that amount of space. - The DFU size change introduces also a change in dfu_api location to 0x103fd0 - Allow GETSTATE and GETSTATUS from runtime mode (optional in DFU spec) - Make dfu_status a .data.shared variable, since it is used from GETSTATUS which we already support in runtime mode - do some led switching while flashing via DFU - disable all non-usb/dbgu interrupts when switching to DFU mode - fix interrupt-storm problem when dbgu is used in DFU loader - add missing linker script for SAM7S128 git-svn-id: https://svn.openpcd.org:2342/trunk@218 6dc7ffe9-61d6-0310-9af1-9938baff3ed1

* Completely separate DFU from application program, we now have a real bootloader.laforge2006-09-131-0/+109
DFU occupies 0x00100000 - 0x00100fff in flash, application starts at 0x00101000. DFU also occupies the first couple of bytes in SRAM, application starts at 0x00200024. In order to produce a samba-flashable image, first build dfu.bin by typing 'make -f Makefule.dfu', succeeded by 'make TARGET=... DEBUG=... BOARD=...' and then concatenating the two files together, e.g. cat dfu.bin main_reqa.bin > flash.bin. Actual flashing via DFU is still not operational, but will be implemented next git-svn-id: https://svn.openpcd.org:2342/trunk@194 6dc7ffe9-61d6-0310-9af1-9938baff3ed1
