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.
