7b9020badf mx27ads: move PBC mapping out of vmalloc space
Before this patch I got the following line in my dmesg:

	[    0.000000] BUG: mapping for 0xd4000000 at 0xeb000000 overlaps vmalloc space

VMALLOC_END is 0xf4000000 and there are the following other mappings
defined for mx27ads:

	(0xa0500000,+0x00001000) maps to 0xffff0000
	(0x10000000,+0x00100000) maps to 0xf4000000
	(0x80000000,+0x00100000) maps to 0xf4100000
	(0xd8000000,+0x00100000) maps to 0xf4200000

So map PBC to 0xf4300000.

be093beb60 [ARM] pass reboot command line to arch_reset()
OMAP wishes to pass state to the boot loader upon reboot in order to
instruct it whether to wait for USB-based reflashing or not.  There is
already a facility to do this via the reboot() syscall, except we ignore
the string passed to machine_restart().

This patch fixes things to pass this string to arch_reset().  This means
that we keep the reboot mode limited to telling the kernel _how_ to
perform the reboot which should be independent of what we request the
boot loader to do.

b7222631c3 mx31: rework of iomux support
This new implemenatation avoids that two physical pins are claimed by
the same driver (also with the the gpr hardware modes).
The gpio kernel lib is also called when a capable gpio pin is assigned
its gpio function.
The mxc_iomux_mode function is still here for backward compatibility but
should not be used anymore.

V2:

In the precendent revision, the iomux code was claiming a pin when its
hardware mode was changed. This was uncorrect: when the hardware mode is
changed, the pin must still be claimed through the iomux.

In order to have a pin working in mode hw2, we must fist issue the
mxc_iomux_set_gpr call and then the corresponding mxc_iomux_mode calls
with the FUNC mode (usually done with mxc_iomux_setup_multiple_pins).
The reverse calls must be done to fee the pins.
