[R/master] Arm multiplatform support

Two of the goals set for Raring arm were to:
a) fold omap3 and omap4 in a single branch
b) ship a single kernel with multi Soc support
so here it is the first batch of patches to:
1) collapse omap3 and omap4 support in master
2) give our kernel arm multiplatform support (TI omap3/4 and Freescale imx6 ATM)
3) enable DTBs for multiple boards support (only needed for imx ATM)
Some comments:
- the Tony Lindgren (9) patches are the actual OMAP multiplatform support (or
actually the missing bits that didn't make the 3.8 window) and are slated for a
3.9 inclusion:
http://git.kernel.org/?p=linux/kernel/git/tmlind/linux-omap.git;a=shortlog;h=refs/heads/omap-for-v3.9/multiplatform-v2
- the Andy Green (3) patches are not strictly necessary, but are the only way to
get a fixed MAC address on pandaboards instead of a random one at every
reboot, and we are already carrying them as part of the omap4 branch:
http://kernel.ubuntu.com/git?p=ubuntu/ubuntu-quantal.git;a=commit;h=f7d0f1eda6a4305fbc4e8d4a41d003ef5b2daf27

The rest are config changes, plus a modification to the way we handle DTBs so we
can specify more than one file.
Main issues with this pull:
omap:
- CPU_FREQ was disabled since mainline is missing some critical pieces for omap4 (and
it leds to all kinds of panics on boot):
http://www.mail-archive.com/linux-omap@vger.kernel.org/msg83951.html
- omap4 pvr driver (3d hw accelerated) is not supported ATM (but vanilla /dev/fb
works fine)
imx6:
- USB_SUSPEND was disabled since it broke usb (but it was ok in 3.7, regression)
- sata was working in 3.7 + 1 patch, but it doesn't work in 3.8
(another regression)
- video output is not working ATM
Last but not least, the generated kernel is still called '-omap' so you need
some tweaking to flash-kernel to install it on imx6, and i would like to rename
it as '-arm' in the future, any thoughts?
As you can imagine it's still a big work in progress but i wanted to pull it now
so we can get some testing, feedback and user space people can do their
plumbing.
Enjoy.
