dm: gpio: Correct use of -ENODEV in drivers
In U-Boot -ENODEV means that there is no device. When there is a problem

When the device tree properties cannot be read correct , they should
return -EINVAL.

It does not look like this driver needs to use a bind() method. It does
not manually create devices with device_bind() nor does it create devices
using U_BOOT_DEVICE(). It seems to only use device tree.
Therefore the manual allocation of platform data is not needed and is

printk: collect printk stuff into <linux/printk.h> with loglevel support
When we import code from Linux, with regular re-sync planned, we want
to use printk() and pr_*(). U-Boot does not support them in a clean
way. So, people end up with local macros, or compat headers here and
there, then we occasionally see build errors of definition conflicts.
We have include/linux/compat.h, but putting all sorts of unrelated
things into a single header is just a temporal workaround. Hence this
patch, to find the best home for all printk variants. If you want to
use printk() and friends, please include <linux/printk.h>. This header
is self-contained, and pulls in only a few headers.
When I was testing this clean-up, I noticed the image size exceeded
its platform limit on some boards. This is because all pr_*() that
were previously defined as no-op in include/linux/mtd/mtd.h (unless
CONFIG_MTD_DEBUG is set), are now enabled.
To make such boards happy, this commit also implements CONFIG_LOGLEVEL.
The concept is similar to the kernel parameter "loglevel". (Actually,
the Kconfig help message was taken from kernel-paremeter.txt of Linux)
Messages with a loglevel smaller than console loglevel will be printed.
The difference is the loglevel is build-time determined. To save the
image size, lower priority pr_*() are compiled out. I set the default
of CONFIG_LOGLEVEL to 6, i.e. pr_notice and higher priority messages
are compiled in.
I adjusted CONFIG_LOGLEVEL to avoid build error for some boards.

sunxi: Remove the MMC index hack
The current code, if there's both an eMMC and an MMC slot available on the
board, will swap the MMC indices based on whether we booted from the eMMC

the index 0.
However, this causes various issues, for example when using other
components that base their behaviour on the MMC index, such as fastboot.
Let's remove that hack, and take the opposite approach. The MMC will always
have the same index, but the bootcmd will pick the same device than the one
we booted from. This is done through the introduction of the mmc_bootdev
environment variable that will be filled by the board code based on the
boot device informations we can get from the SoC.
In order to not introduce regressions, we also need to adjust the fastboot
MMC device and the environment device in order to set it to the eMMC, over
the MMC, like it used to be the case.

nios2: Use asm-generic/io.h
Convert the nios2 architecture to make use of the new asm-generic/io.h to
provide address mapping functions. As nios2 actually performs
non-identity mapping between physical & virtual addresses we can't
simply make use of the generic functions, with the exception of being
able to drop our no-op unmap_physmem() and definitions of unused map
flags.
Feedback from architecture maintainers is welcome.

xtensa: Use asm-generic/io.h
Convert the xtensa architecture to make use of the new asm-generic/io.h
to provide address mapping functions. As the generic implementations are
suitable for xtensa this is primarily a matter of moving code.
This has only been build-tested, feedback from architecture maintainers
