[U-Boot] [PATCH v4 0/4] add dfu support for at91 sam9260 based boards

[Heiko Schocher]

add dfu supprt for at91 sam9260 based boards. The USB
gadget driver is ported from linux:
c94e289f195e: usb: gadget: remove incorrect __init/__exit annotations

it drops a lot of checkpatch warnings/errors:

checkpatch.pl found 12 error(s), 28 warning(s), 38 checks(s)

but for further updates I did not fix them.
The errors are all from this sort:

error: drivers/usb/gadget/at91_udc.c,87: space prohibited before open square bracket '['

a lot of "line over 80 characters" warnings ...

Changes in v4:
- rebase after taurus board changes

Changes in v3:
- new in v3
- add comments from Alexandre Belloni
  get rid of cpu_is_at91*, use newer linux version as
  base for the port to U-Boot.
- adapt changes for U-Boot, as newer linux version is
  used.

Changes in v2:
- add comments from Lukasz Majewski
  - seperate usb gadget driver port from linux into 2 commits
  - first patch original from linux (with complete commit message)
  - second adds U-Boot changes without "#ifdef __UBOOT__"
- new in version 2, contains U-Boot changes
- rebase to bd48c0617b5c7212e5bf22169e716da878842da4
- fix changes introduced through commit:
