[U-Boot-Users] lubbock patch: ram, flash, ethernet

U-Boot support for Lubbock still needs some work, but this fixes a few of the more blatant problems. I look forward to replacing that crufty old "BLOB" with a shiny new U-Boot. :)

I saw some email archived from about 10 months back saying that the TFTP timeout/retry problems went away given PXA timer updates, but like the ethernet patch that was also needed, a patch wasn't posted or merged. Maybe someone who has unmerged PXA updates has the relevant code ready to merge?
