From cbaa118ecfd99fc5ed7adbd9c34a30e1c05e3c93 Mon Sep 17 00:00:00 2001 From: Stuart Menefy Date: Fri, 30 Nov 2007 17:06:36 +0900 Subject: sh: Preparation for uncached jumps through PMB. Presently most of the 29-bit physical parts do P1/P2 segmentation with a 1:1 cached/uncached mapping, jumping between the two to control the caching behaviour. This provides the basic infrastructure to maintain this behaviour on 32-bit physical parts that don't map P1/P2 at all, using a shiny new linker section and corresponding fixmap entry.
