I've tested this on 86xx boards, it'd be great if someone could test on 83xx and 74xx/7xx. 85xx boards should not be affected by

This change assumes http://thread.gmane.org/gmane.comp.boot-loaders.u-boot/63423 has already been applied, or the lib/ppc patches in the diffs below can be changed to lib_ppc.
I'm afraid some 83xx boards will not work after the patch
is applied.
It is some was assuming the data cache locked. (that is
cache-inhibited)
Are you just concerned, or did you actually test the patch, with negative results?
I'm just concerned. I didn't test the patch.
I still don't understand the concern. I think we should go ahead with this patch and if it really shows an issue we can revert it. However, I'm really dont know under what situation that a board has defined CONFIG_SYS_INIT_RAM_LOCK that unlock_ram_in_cache() once we are running in RAM should be an issue.
