flatmem is the total size of available memory.  It's 32K, so if it's
taking 0xa000, you've got a problem :-)

Fedora 9 uses gcc 4.3 which is more stingent than earlier versions.

Thanks for the feedback.

I'll be testing this with the EDK101 tools soon.  Most likely today.

None of the interfaces are stable at this point.
There has been no comprehensive QA of any of the daugherboard code.
All the daughterboard code does not fit at this time.  We're
investigating our options, including overlays loaded out of the flash
at boot time.
