From ffd06e0231ac3fd0c5810f39f6e23527948df1c7 Mon Sep 17 00:00:00 2001 From: York Sun Date: Mon, 8 Oct 2012 07:44:30 +0000 Subject: powerpc/mpc85xx: Rewrite spin table to comply with ePAPR v1.1 Move spin table to cached memory to comply with ePAPR v1.1. Load R3 with 64-bit value if CONFIG_SYS_PPC64 is defined. 'M' bit is set for DDR TLB to maintain cache coherence. See details in doc/README.mpc85xx-spin-table.
