From 982adfc610669482a32127282fe489857a92cfe3 Mon Sep 17 00:00:00 2001 From: Peter Tyser Date: Fri, 10 Jul 2009 18:46:10 -0500 Subject: ppc: Unlock cache-as-ram in a consistent manner Previously, non-e500 architectures only unlocked their data cache which was used as early RAM when booting to Linux using the "bootm" command. This change causes all PPC boards with CONFIG_SYS_INIT_RAM_LOCK defined to unlock their data cache during U-Boot's initialization. This improves U-Boot performance and provides a common cache state when booting to different OSes.
