it is an ARM Barebox image and the destination file is defined by some

This is a re-application of fix 17644b55.
arm_cpu_lowlevel_init() will set the processor mode to 0x13 (supervisor).
When this function is entered via a different processor mode, register
banking will happen to lr (r14), resulting in an invalid return address.
This fix will preserve the return address manually.

The device tree for the 801x variant only contains displays. The
displays are not part of the SoM, but instead of the baseboard,
so they should be described in a baseboard dts. With this patch
we rather include the common tx6x dtsi file and drop 801x from
the barebox device tree names.

The TX6 board come with either NAND flash or eMMC as primary
storage medium. This adds support for the eMMC variants.
We can detect if we have NAND or eMMC by looking at the
bootsource which will be configured accordingly. This
way we can modify the device tree during runtime and do
not have to create a new image.

Since 253fb33 (input: gpio-keys: convert to input framework) the
gpio-buttons are registered with the input framework which has the
side effect that they are activated during boot and no longer have
to be activated manually by activating the input device console.
This reveals that the gpio-button polarities are wrong: The autoboot
is no longer running through since a gpio button press is wrongly
detected.
Fix the polarities in the barebox dts for now to get back a working
board. A proper fix has been sent upstream to the kernel. Once this
has landed and propagated back to barebox this patch can be reverted.

When the kernel load address is chosen by the user/image we need
to check if the kernel needs to relocate itself before decompression.
If that's the case the spacing behind the kernel must allow for this
relocation without overwriting anything placed behind the kernel.

This fixes:
0a37e22d (bootm: use names instead of numbers for image parts)
This commit switches to strings for the image numbers for better FIT
image support (which uses names instead of numbers). These strings
may be NULL when no image number is given. They are used uninitialzed
in several places. Introduce a wrapper function to convert the string
into a number. Check for NULL here in which case we return 0 which
is the correct value.

dev_request_mem_region returns a void * which shall be checked with
IS_ERR(), but in some cases the valid pointer returned clashes with
error values. This is especially the case on some Atmel SoCs.
This introduces dev_request_mem_resource which returns a struct resource
instead which in any case can be checked with IS_ERR(). It's the drivers
responsibility then to get the IOMEM pointer from the resource.

Currently all fastboot flash commands with UBI images are handled by a
final call to 'ubiformat'. This only makes sense for flash commands
where the target file is a mtd device. If we just want to transfer a UBI
image we would expect a simple copy to the correct location.
This patch checks if the destination file is a MTD device by opening it
and calling an ioctl MEMGETINFO. Only for MTD devices, ubiformat is
called.
