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

Conflicts:
	arch/arm/cpu/arm926ejs/mxs/Makefile
	board/compulab/cm_t35/Makefile
	board/corscience/tricorder/Makefile
	board/ppcag/bg0900/Makefile
	drivers/bootcount/Makefile
	include/configs/omap4_common.h
	include/configs/pdnb3.h

Makefile conflicts are due to additions/removals of
object files on the ARM branch vs KBuild introduction
on the main branch. Resolution consists in adjusting
the list of object files in the main branch version.
This also applies to two files which are not listed
as conflicting but had to be modified:

	board/compulab/common/Makefile
	board/udoo/Makefile

include/configs/omap4_common.h conflicts are due to
the OMAP4 conversion to ti_armv7_common.h on the ARM
side, and CONFIG_SYS_HZ removal on the main side.
Resolution is to convert as this icludes removal of
CONFIG_SYS_HZ.

include/configs/pdnb3.h is due to a removal on ARM side.
Trivial resolution is to remove the file.

Note: 'git show' will also list two files just because
they are new:

	include/configs/am335x_igep0033.h
	include/configs/omap3_igep00x0.h
