From 0a371ca08908c9b2a58171223a79bffea1f7c6f5 Mon Sep 17 00:00:00 2001 From: Stefan Roese Date: Tue, 14 Jul 2009 15:53:08 +0200 Subject: ppc4xx: Fix TLB reset problem with recent 44x images Patch d873133f [ppc4xx: Add Sequoia RAM-booting target] broke "normal" booting on some 44x platforms. This breakage is only noticed in some cases while powercycling. As it seems, the code in question in start.S didn't invalidate TLB #0. This makes sense since this TLB is used for the bootrom mapping. With the patch mentioned above even TLB #0 got invalidated resulting in an error later on. This patch now fixes this issue by only invalidating TLB #0 in the RAM- booting case. Tested succesfully on Sequoia and Canyonlands.

An implementation for Canyonlands board is included. The command name is intentionally chosen not to be PPC4xx specific.
