The board/freescale/m54418twr/config.mk defined TEXT_BASE, which has
the same value as CONFIG_SYS_TEXT_BASE. The TEXT_BASE is referenced
by two files:
- arch/m68k/cpu/mcf5445x/start.S and include/
- include/configs/M54418TWR.h
Replace the references with CONFIG_SYS_TEXT_BASE and delete
board/freescale/m54418twr/config.mk.

A number of headers define functions as "extern inline" which is
causing problems with gcc5. The reason is that starting with
version 5.1, gcc defaults to the standard C99 semantics for the
inline keyword.
Under the traditional GNU inline semantics, an "extern inline"
function would never create an external definition, the same
as inline *without* extern in C99. In C99, and "extern inline"
definition is simply an external definition with an inline hint.
In short, the meanings of inline with and without extern are
swapped between GNU and C99.
The upshot is that all these definitions in header files create
an external definition wherever those headers are included,
resulting in multiple definition errors at link time.
Changing all these functions to "static inline" fixes the problem
since this works as desired in all gcc versions. Although the
semantics are slightly different (a static inline definition may
result in an actual function being emitted), it works as intended
in practice.
This patch also removes extern prototype declarations for the
changed functions where they existed.

Since some driver like ohci, lcd used dcache functions. But m68k don't
implement the invalidate_dcache_range()/flush_dcache_range() functions.
To avoid compiling errors this patch adds an weak empty stub function
for all m68k cpu.
Also each cpu can implement its own implementation. If not implemented
then by default is using an empty function.

Introduce a Makefile under arch/$ARCH/ and include it in the
top Makefile (similar to Linux kernel). This allows further
refactoringi like moving architecture-specific code out of global
makefiles, deprecating config variables (CPU, CPUDIR, SOC) or
deprecating arch/$ARCH/config.mk.
In contrary to Linux kernel, U-Boot defines the ARCH variable by
Kconfig, thus the arch Makefile can only included conditionally
after the top config.mk.

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.

This commit adds:
- arch/${ARCH}/Kconfig
provide a menu to select target boards
- board/${VENDOR}/${BOARD}/Kconfig or board/${BOARD}/Kconfig
set CONFIG macros to the appropriate values for each board
- configs/${TARGET_BOARD}_defconfig
default setting of each board
(This commit was automatically generated by a conversion script
based on boards.cfg)
In Linux Kernel, defconfig files are located under
arch/${ARCH}/configs/ directory.
It works in Linux Kernel since ARCH is always given from the
command line for cross compile.
But in U-Boot, ARCH is not given from the command line.
Which means we cannot know ARCH until the board configuration is done.
That is why all the "*_defconfig" files should be gathered into a
single directory ./configs/.

Commit ddc94378d changed the definition of __kernel_size_t
from unsigned int to unsigned long.
It is true that it fixed warnings on some crosstools
but it increased warnings on the others.
The problem is that we cannot see consistency in terms of
the typedef of __kernel_size_t on M68K architecture.
However, I'd like to suggest to have __kernel_size_t to be
unsigned int again.
Rationale:
[1] Linux Kernel defines __kernel_size_t on M68K as unsigned int.
Let's stick to the Linux's way.
[2] We want to build boards with popular pre-built toolchains,
not the one locally-built by indivisuals.
I think m68-linux-gcc which can be downloaded from www.kernel.org
is the candidate for our _recommended_ toolchains.
With this patch, all the m68k boards can be built without any warnings.
Give it a try with the following crosstools:
https://www.kernel.org/pub/tools/crosstool/files/bin/x86_64/4.6.3/
x86_64-gcc-4.6.3-nolibc_m68k-linux.tar.xz
or
https://www.kernel.org/pub/tools/crosstool/files/bin/x86_64/4.9.0/
x86_64-gcc-4.9.0-nolibc_m68k-linux.tar.xz
(The latter is newer.)

The csarX and cscrX registers in the fbcs_t struct are 16-bit for
CONFIG_M5235 and 32-bit wide otherwise. The code in cpu_init.c
accessed them always as 32-bit, effectively creating a wrong memory
access on M5235. Fixed that by choosing out_be16/out_be32 depending
on whether CONFIG_M5235 is defined or not.

gd->bd->bi_baudrate is a copy of gd->baudrate.
Since baudrate is a common feature for all architectures,

Now we are ready to switch over to real Kbuild.
This commit disables temporary scripts:
scripts/{Makefile.build.tmp, Makefile.host.tmp}
and enables real Kbuild scripts:
scripts/{Makefile.build,Makefile.host,Makefile.lib}.
This switch is triggered by the line in scripts/Kbuild.include
-build := -f $(if $(KBUILD_SRC),$(srctree)/)scripts/Makefile.build.tmp obj
+build := -f $(if $(KBUILD_SRC),$(srctree)/)scripts/Makefile.build obj
We need to adjust some build scripts for U-Boot.
But smaller amount of modification is preferable.
Additionally, we need to fix compiler flags which are
locally added or removed.
In Kbuild, it is not allowed to change CFLAGS locally.
Instead, ccflags-y, asflags-y, cppflags-y,
CFLAGS_$(basetarget).o, CFLAGS_REMOVE_$(basetarget).o
are prepared for that purpose.
