Modify tegra-common-post.h's BOOTCOMMAND definition to use the generic filesystem command load rather than separate fatload and ext2load. This removes the need to iterate over supported filesystem types in the boot command. This requires editing all board config headers to enable the new commands. The now-unused commands are left enabled to assue backwards compatibility with any user scripts. Boards (all from Avionic Design) which define custom BOOTCOMMAND values are not affected.

|
|
* data passed to the kernel shouldn't overlap the start of RAM. Pushing
|
|
* this up to 16M allows for a sizable kernel to be decompressed below the

|
|
* fdt_addr_r simply shouldn't overlap anything else. Choosing 32M allows for

|

*
|
|
* ramdisk_addr_r simply shouldn't overlap anything else. Choosing 33M allows
|
|
* for the FDT/DTB to be up to 1M, which is hopefully plenty.
