From b5f65dfa9aa8e068e62aba4733dc4fd97b1d9bf6 Mon Sep 17 00:00:00 2001 From: Haiying Wang Date: Tue, 13 Jan 2009 16:29:28 -0500 Subject: [PATCH] Some changes of TLB entry setting for MPC8572DS - Move the TLB entry of PIXIS_BASE from TLB0 to TLB1[8], because in CAMP mode, all the TLB0 entries will be invalidated after cpu1 brings up kernel, thus cpu0 can not access PIXIS_BASE anymore (any access will cause DataTLBError exception) - Set CONFIG_SYS_DDR_TLB_START to 9 for MPC8572DS board.
