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?
