Linux was not able to boot with initrd. Resolved by increasing offset for FDT.

Thanks Rony/Shivamurthy,

I've applied this patch locally and I'll push it out later today with some other changes.

I haven't tested it as I don't know how, but I've tested the the existing functionality and it still works.
