Subject: powerpc/47x: Use the new ppc-opcode infrastructure
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=1afc149def25ac1c44a83882f6c0e42a8e88ce9f;p=openwrt%2Fstaging%2Fblogic.git

powerpc/47x: Use the new ppc-opcode infrastructure

Don't use 47x only #defines for TLBIVAX or ICBT, supply and use helpers
in ppc-opcode.h

This fixes a compile breakage.
