Add support for re-relocation malloc() in arm's start-up code.

Signed-off-by: Simon Glass <sjg@chromium.org>

At present arm defines CONFIG_SYS_GENERIC_GLOBAL_DATA, meaning that
the global_data pointer is set up in board_init_f(). However it is
actually set up before this, it just isn't zeroed.

If we zero the global data before calling board_init_f() then we
don't need to define CONFIG_SYS_GENERIC_GLOBAL_DATA.

Make this change (on arm32 only) to simplify the init process. I
don't have the ability to test aarch64 yet.

For e500mc cores the watchdog timer period has to be set by means of a
6bit value, that defines the bit of the timebase counter used to signal
a watchdog timer exception on its 0 to 1 transition.
The macro used to set the watchdog period TCR_WP, was redefined for e500mc
to support 6 WP setting.

The parameter (x) given to the macro specifies the prescaling factor of
the time base clock (fTB):

watchdog_period = 1/fTB * 2^x

Now the primary data for each board is in Kconfig, defconfig and
MAINTAINERS.

It is true boards.cfg is needed for MAKEALL and buildman and might be
useful to brouse all the supported boards in a single database.
But it would be painful to maintain the boards.cfg in sync.

So, this is the solution.
Add a tool to generate the equivalent boards.cfg file based on
the latest Kconfig, defconfig and MAINTAINERS.

We can keep all the functions of MAKEALL and buildman with it.

The best thing would be to change MAKEALL and buildman for not
depending on boards.cfg in the future, but it would take some time.

information from it.

The MAINTAINERS format as in Linux Kernel would be nice
because we can crib the scripts/get_maintainer.pl script.

After some discussion, we chose to put a MAINTAINERS file under each
board directory, not the top-level one because we want to collect
relevant information for a board into a single place.

This commit enables Kconfig.
Going forward, we use Kconfig for the board configuration.
mkconfig will never be used. Nor will include/config.mk be generated.

Kconfig must be adjusted for U-Boot because our situation is
a little more complicated than Linux Kernel.
We have to generate multiple boot images (Normal, SPL, TPL)
from one source tree.
Each image needs its own configuration input.

Usage:

Run "make <board>_defconfig" to do the board configuration.

It will create the .config file and additionally spl/.config, tpl/.config
if SPL, TPL is enabled, respectively.

You can use "make config", "make menuconfig" etc. to create
a new .config or modify the existing one.

Use "make spl/config", "make spl/menuconfig" etc. for spl/.config
and do likewise for tpl/.config file.

The generic syntax of configuration targets for SPL, TPL is:

  <target_image>/<config_command>

Here, <target_image> is either 'spl' or 'tpl'
      <config_command> is 'config', 'menuconfig', 'xconfig', etc.

When the configuration is done, run "make".
(Or "make <board>_defconfig all" will do the configuration and build
in one time.)

For futher information of how Kconfig works in U-Boot,
please read the comment block of scripts/multiconfig.py.

By the way, there is another item worth remarking here:
coexistence of Kconfig and board herder files.

Prior to Kconfig, we used C headers to define a set of configs.

We expect a very long term to migrate from C headers to Kconfig.
Two different infractructure must coexist in the interim.

In our former configuration scheme, include/autoconf.mk was generated
for use in makefiles.
It is still generated under include/, spl/include/, tpl/include/ directory
for the Normal, SPL, TPL image, respectively.
