Right. These are the relevant commits; they went into mainline some
time ago:
commit 27dd5f8e1062684f1ba685760409d9b2ab6691bf
Author: Stefan Roese <s...@denx.de>
Date: Tue Jul 28 10:56:03 2009 +0200
ppc4xx: amcc: Move "kernel_addr_r" etc to higher locations (> 16MB)
This patch moves the load addresses for kernel, fdt and ramdisk to higher
addresses (>= 16MB). This enables booting of bigger kernel images (e.g.
lockdep enabled).

commit 6942efc2be1b90054fa4afa5cda7023469fe08b9
Author: Stefan Roese <s...@denx.de>
Date: Tue Jul 28 10:50:32 2009 +0200
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.
