[PATCH 0/2] omap3evm: Enable Linux boot

[PATCH 0/2] omap3evm: Enable Linux boot

[Sanjeev Premi]

These patches are necessary enable Linux boot from
barebox.bin.

Both patches apply against the 'next' branch at:

Linux still doesn't boot successfully, and changes
are necessary in the defconfig and default env.
Will submit the patches once I have done some more
debug.

Will share the failure log in reponse to this patch
(just to prevent clutter in this description).

My local init script uses this command to boot Linux:
bootm -c -v /mnt/uImage

As noted in the original description, Linux doesn't boot
successfully. Debugger indicates an exception - but need
to investigate further.

Here is the log:

The changes are obviously correct, applied to -master.
