Sorry about the confusion.  It was meant to say that the first block
is smaller than the U-Boot Binary.

So I guess that my best option would be to use a small primary
bootloader to boot U-Boot from RAM.

If I am reading everything correctly, I should have to change the
reset and start locations (.resetvec and .bootpg) along with the setup
of the MMU (as all TLB Entries are cleared currently.)

I'm probably missing other steps that are required, I'll be looking at
the startup code in more detail.

Do you see any reasons why what I am suggesting may not be feasible at
all?  I would really like to use U-Boot as our bootloader (or
secondary bootloader) if it is at all possible.

Regards,
