As we re-locate the entire sam7dfu program into RAM, we don't need
to execute from flash and can thus re-program the DFU partition
via the DFU protocol itself (alternate setting '1').
We also implement downloading executable code into RAM using
alternate setting '2'. The latter part is not properly executed yet.
add new RUN_FROM_RAM run-mode for direct DFU-to-RAM support2011-07-29T22:37:04+00:00Harald Weltelaforge@gnumonks.org2011-07-29T22:37:04+00:00urn:sha1:5a8cd9feca7d0d09aee736ff804be4967828aefduse gcc/ld flags -ffunction-sections and --gc-sections2011-07-29T22:34:59+00:00Harald Weltelaforge@gnumonks.org2011-07-29T22:34:59+00:00urn:sha1:dda0896d875ec2d33b6de94df818a2f94526272b

- we increase the DFU size from 4k to 16k size. This is mainly due to the2006-09-22T21:29:57+00:00laforgelaforge@6dc7ffe9-61d6-0310-9af1-9938baff3ed12006-09-22T21:29:57+00:00urn:sha1:1c2b1d22016957bebe0a49c9069b85815f7cf936
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
