Marek has sent all cache relevant patches together in the same patchset.
If I am not wrong, your V4 was sent as :


and he added his own Ack.

For FEC it is easier as for ESDHC. The controller on PowerPC has the
same name, but it is different - and there is  a different driver. The
fec_mxc.c is only for i.MX SOCs, and we are sure we do not break other
architectures, except i.MX. I know it breaks MX3x, I will check it.

The whole serie depends on the first patch:

This must be acked / merged by Albert, because it is for all arm926 SOCs.
