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

Testing: with http://paste.ubuntu.org.cn/2522971 (4.0-rc1 patch)

Beagle-XM: this is a r3p2 cortex-a8 Before: CPUID=0x413fc082 ACR=0x000000e2 L2AUXCR=0x00000042 After: CPUID=0x413fc082 ACR=0x00000042 L2AUXCR=0x00000042 To emulate matt's board, I hacked u-boot to force the code flow. Testing with (hack http://paste.ubuntu.org.cn/2525559): CPUID=0x413fc082 ACR=0x000000e2 L2AUXCR=0x00000042
I dont have access to other omap3 platforms to give a better coverage, so, I welcome as much testing as possible.
