Merge branch 'master' of git://git.denx.de/u-boot-arm
Albert's rework of the linker scripts conflicted with Simon's making
everyone use __bss_end. We also had a minor conflict over
README.scrapyard being added to in mainline and enhanced in
u-boot-arm/master with proper formatting.
Conflicts:

Build tested for all of ARM and run-time tested on am335x_evm.
