At present banks must be named and it is not possible to refer to GPIOs by
number in driver model. Some boards use numbering - e.g. OMAP. It is fairly
easy to support by detecting the absense of a bank name (which starts with
a letter).

Add support for numbered GPIOs in addition to the existing bank support.

Without the private libgcc, we need a full multilib toolchain with
different libgcc or multiple toolchains to build all BE/LE and
hard-float/soft-float variants of MIPS boards.  That is not feasible.

This commit allows us to build all the MIPS boards with a single
kernel.org toolchain:

https://www.kernel.org/pub/tools/crosstool/files/bin/x86_64/4.9.0/
x86_64-gcc-4.9.0-nolibc_mips-linux.tar.xz

This change sounds reasonable for most users.  If necessary,
you can disable this option via "make menuconfig" or friends.

When spl/.config is updated by "make spl/menuconfig" or friends,
spl/include/config/auto.conf, spl/include/generated/autoconf.h

There is no hook for SPL in the top Makefile, so this commit

The private libgcc is supported only on ARM, MIPS, PowerPC, SH, x86.
Those architectures should "select" HAVE_PRIVATE_LIBGCC and

The motivation of this commit is to change CONFIG_USE_PRIVATE_LIBGCC
to a boolean macro so we can move it to Kconfig.

In the current implementation, there are two forms of syntax
for this macro:

  - CONFIG_USE_PRIVATE_LIBGCC=y
  - CONFIG_USE_PRIVATE_LIBGCC=path/to/private/libgcc

The latter is only used by x86 architecture.
With a little bit refactoring, it can be converted to the former.

CONFIG_SYS_HZ is always defined as 1000 in config_fallbacks.h
(but some boards still have redundant definitions).

This commit moves the definition and the document in README to
Kconfig.  Since lib/Kconfig can assure that CONFIG_SYS_HZ is 1000,
the sanity check in lib/time.c should be removed.

This patch integrates the Barebox version of this kwbimage.c file into
U-Boot. As this version supports the image version 1 type for the
Armada XP / 370 SoCs.

It was easier to integrate the existing and known to be working Barebox
source than to update the current U-Boot version to support this
v1 image header format. Now all Marvell MVEBU SoCs are supported:

Image type 0: Kirkwood & Dove
Image type 1: Armada 370 & Armada XP

Please note that the current v1 support has this restuction (same as
has Barebox version):

Not implemented: support for the register headers and secure headers
in v1 images

The barebox version of the kwboot tool has evolved a bit. To support
Armada XP and Dove. Additionally a few minor fixes have been applied.
So lets sync with the latest barebox version.

Please note that the main difference between both versions now is, that
