When SDRAM reaches to the end of the address space the comparison
membase + memsize evaluates to 0, so pc - membase < memsize can never
be true. Fix this by substracting membase on both sides of the
comparison.

In v4.2-rc3 the "fsl,imx1-gpt" compatible was replaced with
"fsl,imx21-gpt" so i.MX27 currently ends up without clocksource. Fix

The TX6 boards come with 3 different PMIC variants from which we
currently only support the ltc3673. Detect the other two by i2c
address and set them up correctly. The code is based on the karo

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 i.MX6q variant is basically the same as the i.MX6dl variant, just

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.

U-Boot_mod is a popular bootloader for Atheros AR93xx chips,
please see https://github.com/pepe2k/u-boot_mod for details.
It's reasonable to import some lowlevel AR9331 initialization
code from U-Boot_mod.
AR9331 (Hornet) 1.1 currently needs an additional
