[U-Boot] [RFC] Board support patches for the eXMeritus HWW-1U-1A devices

[Kyle Moffett]

Hello all!

This is my first U-Boot submission, so my apologies if there are any coding
style or conventions issues.  Please let me know and I'll get them fixed up
shortly.

In addition, these patches were based on v2010.03 and I realize that the
upstream may have diverged a bit since then.  Please let me know what
GIT version I should rebase these patches on for future submissions.

The eXMeritus HWW-1U-1A unit is a DO-160-certified 13lb 1U chassis
with 3 independent TEMPEST zones.  Two independent P2020 computers may
be found inside each zone.  Complete hardware support is included.

There are a couple preliminary patches to common code, but basically
everything else is limited to our own board-support code.

I look forward to your comments and criticisms!

Cheers,
Kyle Moffett
