arm: add Calxeda Highbank support

Hi,

v3:
reset: add missing wfi
gpio: move probe to board
add oftree probe support

v2:
fix cc tag so Rob can receive the patch
add oftree support to xgmac

The following patch serie add the support of the Quad Core Cortex-A9 Highbank from Calxeda

As I do not have the real hardware this is only tested on qemu

Rob could confirm if this work on real hw

This patch serie depends on the amba sp804 patch and the ahci patch serie

The following changes since commit ddec6455ac75cad442be1247ae265b539c54ebfe:

amba: add oftree probe support (2013-02-13 02:35:56 +0800)

are available in the git repository at:

git://git.jcrosoft.org/barebox.git delivery/highbank

for you to fetch changes up to 1d6b912a9a89b0bdf7915026d938f40aba13b581:

highbank: use the provided dtb by the firmware to probe barebox device and mem size (2013-02-13 02:35:56 +0800)

----------------------------------------------------------------
Jean-Christophe PLAGNIOL-VILLARD (6):
ahci-generic: add oftree support
of: make of_add_memory available for other board
highbank: add xgmac support
arm: add highbank support
highbank: add l2x0 support
highbank: use the provided dtb by the firmware to probe barebox device and mem size

so when the first stage booloader of firmware provide the dtb we can use it to probe the memory

also allow to print what we probe
