From 6942efc2be1b90054fa4afa5cda7023469fe08b9 Mon Sep 17 00:00:00 2001 From: Stefan Roese Date: Tue, 28 Jul 2009 10:50:32 +0200 Subject: ppc4xx: amcc: Set CONFIG_SYS_BOOTMAPSZ to 16MB for big kernels This patch changes CONFIG_SYS_BOOTMAPSZ from 8MB to 16MB which is the initial TLB on 40x PPC's in the Linux kernel. With this change even bigger Linux kernels (> 8MB) can be booted. This patch also sets CONFIG_SYS_BOOTM_LEN to 16MB (default 8MB) to enable decompression of bigger images.
