Subject: [POWERPC] Split out asm-ppc/mmu.h portions for Freescale Book-E
X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=67f74c9d223815e30eac456b4956a846143b65c6;p=openwrt%2Fstaging%2Fblogic.git

[POWERPC] Split out asm-ppc/mmu.h portions for Freescale Book-E

arch/powerpc still relies on asm-ppc/mmu.h for some 32-bit MMU types.
This patch is another step towards fixing this.  It takes the portions
of asm-ppc/mmu.h related to Freescale Book-E which are still relevant
in arch/powerpc and puts them in a new asm-powerpc/mmu-fsl-booke.h,
included when appropriate from asm-powerpc/mmu.h.
