From mboxrd@z Thu Jan 1 00:00:00 1970 Return-Path: Date: Fri, 15 Jun 2007 15:33:09 +1000 From: David Gibson To: linuxppc-dev@ozlabs.org Subject: Split out asm-ppc/mmu.h portions for Freescale Book-E Message-ID: <20070615053309.GA3910@localhost.localdomain> MIME-Version: 1.0 Content-Type: text/plain; charset=us-ascii List-Id: Linux on PowerPC Developers Mail List List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , 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. Signed-off-by: David Gibson --- Could someone who actually has a Freescale Book-E board give this a whirl? I've compile tested this, but not booted it.
