Hi Jean Thanks for accepting my earlier patch "arch_misc_init support for ARM architectures" Can you please re-think for this patch too. This patch is nothing but outcome of our earlier discussion/abstraction to create Generic Cache header for ARM
Also kirkwood Soc support patches are almost done (I think so :-) ) Kirkwood users are very keen to use them right from next release
How I can assist you to get them through? Shall I resubmit them with the dependency follow-up as suggested by Wolfgang? Reference : http://lists.denx.de/pipermail/u-boot/2009-May/053509.html
Regards.. Prafulla . .
