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: arch/arm/cpu/ixp/u-boot.lds arch/arm/cpu/u-boot.lds arch/arm/lib/Makefile board/actux1/u-boot.lds board/actux2/u-boot.lds board/actux3/u-boot.lds board/dvlhost/u-boot.lds board/freescale/mx31ads/u-boot.lds doc/README.scrapyard include/configs/tegra-common.h Build tested for all of ARM and run-time tested on am335x_evm.
