From 3a1f5c81b0b9557817a789bece839905581c2205 Mon Sep 17 00:00:00 2001 From: Stefan Roese Date: Fri, 22 Jun 2007 16:58:40 +0200 Subject: [PATCH] ppc4xx: Fix problem with extended program_tlb() funtion The recently extended program_tlb() function had a problem when multiple TLB's had to be setup (for example with 512MB of SDRAM). The virtual address was not incremented. This patch fixes this issue and is tested on Katmai with 512MB SDRAM.
