powerpc: Add a new platform for maple so a different link address can be set
PATCH 1/1 powerpc: Add a new platform for maple so a different link address can be set
From: Corey Minyard <[email protected]>
The maple platform failed to load because it's firmware could not take a link address of 0x4000000. A new platform type with a link address of 0x400000 had to be created for the maple.

Without this patch the firmware loader says it is unable to parse the ELF header and dies. This patch lets 2.6.31 boot without issue. At the current head of k.org git, at least with an NFS mount, I'm getting:
Kernel panic - not syncing: No init found
So I'm not sure what the deal is there, but this patch is still required to get the firmware to load the kernel.
