 decompression of bigger images.

Applied to u-boot-ppc4xx/master. Thanks.

Best regards,

[U-Boot] [PATCH v2] ppc4xx: amcc: Set CONFIG_SYS_BOOTMAPSZ to 16MB for big kernels

[Stefan Roese]

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.

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
