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. Signed-off-by: Stefan Roese <sr@denx.de>
