Now that -rc3 is out, here's this one rebased on v3.8-rc3 as requested
by Olof.

Regards,

Tony


The following changes since commit 9931faca02c604c22335f5a935a501bb2ace6e20:

  Linux 3.8-rc3 (2013-01-09 18:59:55 -0800)

are available in the git repository at:

  git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap tags/omap-for-v3.9/multiplatform-enable-signed-v2

for you to fetch changes up to ad1bb1b4e01c5ecbe32133ce6921d0e76cb76dcf:

  ARM: OMAP2+: Remove now obsolete uncompress.h and debug-macro.S (2013-01-11 11:24:20 -0800)

----------------------------------------------------------------
The last dependency for enabling multiplatform support for omap2+ is now
finally gone with commit 62e4d357 (ARM: 7609/1: disable errata work-arounds
which access secure registers) that was preventing booting omap4.

Note that make uImage will no longer work properly because of unspecified
load address, so uImage needs to be created manually with:

$ mkimage -A arm -O linux -T kernel -C none -a 0x80008000 -e 0x80008000 \
	-n "Linux" -d zImage-omap2plus uImage-omap2plus

You can also boot minimal vexpress configuration using qemu with:

$ qemu-system-arm -machine vexpress-a9 -m 1024 -net nic -net user -serial stdio \
	-append "console=ttyAMA0,115200n8 rw root=/dev/mmcblk0p2 rootwait" \
	-kernel zImage-omap2plus -initrd initrd.img -sd rootfs.img

Please note that some custom defconfigs now need to be updated to include
the following options:

CONFIG_ARCH_MULTIPLATFORM=y
CONFIG_ARCH_MULTI_V7=y
CONFIG_ARCH_OMAP2PLUS=y

And possibly also:

CONFIG_ARCH_MULTI_V6=y

Updating is needed at least for RMK's minimal allnoconfig files.

And if you need DEBUG_LL for earlyprintk, you now have to select the
debug port manually with Kconfig.

Pulled, thanks!

Enabling multiplatform with a net negative patch delta -- awesome!
