A lot of files rely on include/driver.h including include/of.h (and
this including include/errno.h. include the files explicitly so we can
eventually get rid of including of.h from driver.h

Convert to static inline functions and use lower case letters for function
names. Also, include mach/debug_ll.h when an architecture provides support
for debug_ll, not only when it's actually enabled. This allows architecures
to put some UART initialization code into mach/debug_ll.h which is compiled
out when debug_ll is disabled.

The esdctl devices are currently not in the devicetrees. this means
they are not registered when booting from the devicetree. Move the
device registration from soc_devices_init to soc_init which is called
even with devicetree support so that we get esdctl devices.

gpiolib user have nothing to define in their machine
specific gpio.h, so do not include it.
The only thing they could define would be ARCH_NR_GPIOS,
but currently no architecture defines it. Should an architecure
feel the need to do it this would be a good opportunity to
get rid of this limitation.

With multiboard support the compiletime generated BOARDINFO string
gets more and more meaningless. This removes it from Kconfig and
replaces it with a variable that can be set at boardlevel.
Also many boards have a standard setting for the hostname in the
environment. This patch also moves the standard to C code by calling
barebox_set_hostname().

We used to pass the DCD data from the boards. This patch allows
to optionally skip passing DCD data. In this case the DCD data
from the flash image is used if present.

This adds support for the Phytec phyFLEX-i.MX6 board. The phyFLEX-i.MX6
is a system-on-module based on the Freescale i.MX6 SoC. This patch supports
the 1GiB and 2GiB variants on a PBA-B-01 baseboard.

The i.MX6 uses the same GPMI NAND controller as i.MX23/28 do. This adds
i.MX6 support to the driver.

The ifdefs around the SoC specific boot_nand_external functions
can be removed when all functions go into their own sections so
that the linker can discard the unused functions.
This also adds a #ifdef BROKEN around the i.MX21 code which currently
does not have the imx21_barebox_entry function.

Instead of ifdeffing out the correct NFC base address just pass

Add support for the GK802 'QUAD CORE Mini PC', which seems to be loosely

It is supposedly identical to the Hiapad Hi802.

This reverts commit 08c0e206b3.
The external NAND boot code currently uses the _text linker variable
to determine a place for the image. This doesn't work with multi image
support which will link the binary at 0x0. Revert multi image support
for the pcm038 for now until a solution is found.

In principle we could build barebox for multiple i.MX SoCs, so

This adds the make infrastructure to build multiple SoC or
board specific images from a single barebox binary.
The basic idea is that we no longer have a single pbl, but instead
multiple pbls, one per image if necessary. Each pbl is defined
by its entry function so that each pbl can do exactly what a given
board needs. Additionally the pbls together with a self extracting
barebox binary can be encapsulated in specific image formats.
squashed in build fixes from Lucas Stach for make version >= 3.82:
Split Multimage Makefile rule in explicit and implicit parts
Fixes build with make version >=3.82
Frome the make 3.82 NEWS file:
* WARNING: Backward-incompatibility!
In previous versions of make it was acceptable to list one or more explicit
targets followed by one or more pattern targets in the same rule and it
worked "as expected". However, this was not documented as acceptable and if
you listed any explicit targets AFTER the pattern targets, the entire rule
would be mis-parsed. This release removes this ability completely: make
will generate an error message if you mix explicit and pattern targets in
the same rule.

The same value as used in Mainline and Freescale U-Boot. This might
increase the stability of i.MX51 boards. The 5:1 ratio we have in barebox
probably goes back to copy/paste from the i.MX53 code.
