Subject: powerpc/44x: Enable CRASH_DUMP for 440x
X-Git-Tag: next-20111221~86^2~2
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=5b2e478da032b7d443833402fa586f832397f3be;p=karo-tx-linux.git

powerpc/44x: Enable CRASH_DUMP for 440x

Now that we have relocatable kernel, supporting CRASH_DUMP only requires
turning the switches on for UP machines.

We don't have kexec support on 47x yet. Enabling SMP support would be done
as part of enabling the PPC_47x support.
