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.
Signed-off-by: Stefan Roese sr@denx.de --- This patch replaces the orinal patch "[PATCH v2] ppc4xx: amcc: Set CONFIG_SYS_BOOTMAPSZ to 16MB to enable booting of big kernels".
v2: - Patch subject line now a bit shorter - Increase CONFIG_SYS_BOOTM_LEN to 16MB too
