The fifth incarnation should be proper, I hope. (skipping all the blurb and pointing to v1 for the blurb).
Changes since v4:
- smc is back to handassembled thanks to gcc versions
- fixes in multiple call handling within cpu_init_cp15 -> thanks to Matt Porter's test log showing fail on r1p3 cortex-a8 (where the errata must be applied)
v4: http://thread.gmane.org/gmane.comp.boot-loaders.u-boot/213863 V3: http://thread.gmane.org/gmane.comp.boot-loaders.u-boot/213207/focus=213307 V2: http://comments.gmane.org/gmane.comp.boot-loaders.u-boot/213060 V1: http://comments.gmane.org/gmane.comp.boot-loaders.u-boot/212174
This time, the series is based on u-boot master git://git.denx.de/u-boot.git master 694cc87b76b1 arm, da8xx: convert ipam390 board to generic board support
Git tree: https://gitorious.org/nm-kernel/u-boot-nm (at least till gitorious is around..) branch errata-v5-master-694cc87b76b1
Git link: https://gitorious.org/nm-kernel/u-boot-nm.git errata-v5-master-694cc87b76b1
Testing: with http://paste.ubuntu.org.cn/2522971 (4.0-rc1 patch)
If folks have a older beagle around and dont want to startup the kernel for this, http://paste.ubuntu.org.cn/2525810 is a trivial patch to dump the same from the bootloader.

I dont have access to other omap3 platforms to give a better coverage, so, I welcome as much testing as possible.
