Recent GCC versions warn if the format string is not a literal
because the compiler cannot check the argument validity at compile
time.
Commit 192bc6948b ("Fix GCC format-security errors and convert
sprintfs.") blindly replaced sprintf() with strcpy(), including
many cases where the format parameter is a string literal.
For the kconfig change:
sprintf(header, " ");
..., here the format parameter is a string literal " ", so it is
definitely equivalent to:
strcpy(header, " ");
Of course, if the 'header' did not have enough length for containing
" ", it would be a security problem, but another problem. (in this
case, the 'header' is 4 byte length buffer, so it is not a problem at
all.)
The kconfig code is kept as synced with Linux as possible, but this
change made the code out-of-sync for nothing. Just reverting.

After consulting with some of the SPDX team, the conclusion is that
Makefiles are worth adding SPDX-License-Identifier tags too, and most of
ours have one. This adds tags to ones that lack them and converts a few
that had full (or in one case, very partial) license blobs into the
equivalent tag.

I might have missed something, but I failed to use the escape char '\'
in strings. To pass a printf format string like "foo %d bar\n" via
Kconfig to the code.
Right now its not possible to use the escape character '\' in Kconfig
string values correctly to e.g. set this string value "test output\n".
The '\n' will be converted to 'n'.
The current implementation removes some of the '\' chars from the input
string in conf_set_sym_val(). Examples:
'\' -> ''
'\\' -> '\'
'\\\' -> '\'
'\\\\' -> '\\'
...
And then doubles the backslash chars in the output string in
sym_escape_string_value(). Example:
'\' -> '' -> ''
'\\' -> '\' -> '\\'
'\\\' -> '\' -> '\\'
'\\\\' -> '\\' -> '\\\\'
...
As you see in these examples, its impossible to generate a single '\'
charater in the output string as its needed for something like '\n'.
This patch now changes this behavior to not drop some backslashes in
conf_set_sym_val() and to not add new backslashes in the resulting
output string. Removing the function sym_escape_string_value()
completely as its not needed anymore.

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.
