abcaa6ee2a am33xx: Make SoC bootcount driver have its own symbol
Some am33xx boards may not use the RTC block for bootcount (as it may
not be wired up for the board) and use some other facility.  So add
another symbol for the bootcount driver for the IP block.

eda0ba38a8 bootcount: store bootcount var in environment
If no softreset save registers are found on the hardware
"bootcount" is stored in the environment. To prevent a
saveenv on all reboots, the environment variable
"upgrade_available" is introduced. If "upgrade_available" is
0, "bootcount" is always 0 therefore no need to save the
environment on u-boot boot, if "upgrade_available" is 1 "bootcount"
is incremented in the environment and environment gets written
on u-boot start.
So the Userspace Applikation must set the "upgrade_available"
and "bootcount" variable to 0 (for example with fw_setenv),
if a boot was successfully.

85b8c5c4bf 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

22ee397504 bootcount_davinci: Switch to scratch register #2
The RTC IP block here provides 3 scratch registers.  Currently when
using DeepSleep on am335x the scratch0/1 registers are used so moving
ourself to scratch2 makes cooperation easier.

0044c42e94 Consolidate bootcount code into drivers/bootcount
This patch moves all bootcount implementations into a common
directory: drivers/bootcount. The generic bootcount driver
is now usable not only by powerpc platforms, but others as well.
