Merge branch 'u-boot/master' into 'u-boot-arm/master'

Conflicts:
	Makefile
	drivers/net/npe/Makefile

These two conflicts arise from commit 0b2d3f20
("ARM: NET: Remove the IXP NPE ethernet driver") and are
resolved by deleting the drivers/net/npe/Makefile file
and removing the CONFIG_IXP4XX_NPE line from Makefile.
