"panda" config and build doesn't work on panda ES at all

"panda" config and build doesn't work on panda ES at all

[Robert P. J. Day]

  just for fun, i configured and built MLO and barebox.bin for the
panda, then tried to use that on a panda ES -- got no response
whatever from minicom.  i did verify that i could boot to barebox just
fine on a regular panda, though.

  this is different from the case of a regular beagle and beagle xM,
for which the MLO and barebox.bin boot just fine on an xM, so there's
clearly a significant difference between those two panda variants as
far as barebox is concerned.  i haven't had any time to look at it in
more detail yet.

We should add some information about that here:

http://wiki.barebox.org/doku.php?id=boards:texas_instruments_panda
http://wiki.barebox.org/doku.php?id=boards:texas_instruments_beagle

So what variants of these boards are out there?

Panda 'regular'
Panda ES
Beagle 'regular'
Beagle xM

Do these correspond somehow to the revisions printed on the board?
I have a Beagle rev C3 and a Panda rev A1.

  i'll write something up and ask the beagle & panda lists to take a
look.

Panda ES has a OMAP4460 @ 1.2GHz Panda has a OMAP4430 @ 1GHz.
This patch series shows that some changes are really needed to switch
from the 4430 to the 4460 :
