Our build system still parses ad-hoc CONFIG options in header files
and generates include/autoconf.mk so that Makefiles can reference
them.  This gimmick was introduced in the pre-Kconfig days and will
be kept until Kconfig migration is completed.

The include/autoconf.mk is generated like follows:

  [1] Preprocess include/common.h with -DDO_DEPS_ONLY and
      retrieve macros into include/autoconf.mk.tmp
  [2] Reformat include/autoconf.mk.dep into include/autoconf.mk
      with tools/scripts/define2mk.sed script
  [3] Remove include/autoconf.mk.tmp

Here, include/autoconf.mk.tmp is similar to u-boot.cfg, which is
also generated by preprocessing include/config.h with -DDO_DEPS_ONLY.
In other words, there is much overlap among include/autoconf.mk and
u-boot.cfg build rules.

So, the idea is to split the build rule of include/autoconf.mk
into two stages.  The first preprocesses headers into u-boot.cfg.
The second parses the u-boot.cfg into include/autoconf.mk.  The
build rules of u-boot.cfg in Makefile and spl/Makefile will be gone.

I am going to move the build rule of u-boot.cfg.  Before that,
no_new_adhoc_configs_check must be tweaked to not depend on it.

The ad-hoc option check can be done at the end of build, along
with other checks.

Prior to the previous patch, a freshly created .u-boot.cfg.cmd may not
correctly represent all dependencies for u-boot.cfg. The previous change
only solved this issue for fresh builds; when performing an incremental
build, the deficient .u-boot.cfg.cmd is already present, so u-boot.cfg
is not rebuilt, and hence .u-boot.cfg.cmd is not rebuilt with the correct
content.

Solve this by explicitly detecting when the dependency file .u-boot.cfg.d
has not been integrated into .u-boot.cfg.cmd, and force u-boot.cfg to be
rebuilt in this case by deleting it first. This is possible since
if_changed_dep will always delete .u-boot.cfg.d when it executes
successfully, so its presence means either that the previous build was
made by a source tree that contained a Makefile that didn't include the
previous patch, or that the build failed part way through executing
if_changed_dep for u-boot.cfg. Forcing a rebuild of u-boot.cfg is required
in the former case, and will cause no additional work in the latter case,
since the file would be rebuilt anyway for the same reason it was being
rebuilt by the previous build.

cmd_cpp_cfg generates a dependency output, but because it's invoked using
if_changed rather than if_changed_dep, that dependency file is ignored.
This results in Kbuild not knowing about which files u-boot.cfg depends
on, so it may not be rebuilt when required.

A practical result of this is that u-boot.cfg may continue to reference
CONFIG_ options that no longer exist in the source tree, and this can
cause the adhoc config options check to fail.

This change modifies Makefile to use if_changed_dep, which in turn causes
all dependencies to be known to the next make invocation.

This general MMDC driver adds basic support for Freescale MMDC
(Multi Mode DDR Controller). Currently MMDC is integrated on ARMv8
LS1012A SoC for DDR3L, there will be a update to this driver to
support more flexible configuration if new features (DDR4, multiple
controllers/chip selections, etc) are implimented in future.

Meantime, reuse common MMDC driver for LS1012ARDB/LS1012AQDS/
LS1012AFRDM.
