36dd5f1b8a dtc: Switch to building and using our own dtc unless provided
This makes us act like the Linux Kernel does and allow for dtc to be
provided externally but otherwise we use the version of dtc that is
included in the sources.  This in turn means that we can drop the
checkdtc logic.  We select DTC in the cases where we will need the dtc
tool provided.

4a85663ec7 kbuild: Enable -fshort-wchar
EFI_LOADER really wants UTF-16 strings (ie. %ls and L"string" are 16bit
chars instead of 32bit chars).  But rather than enabling -fshort-wchar
conditionally if EFI_LOADER is enabled, it was deemed preferrable to
globally switch.

5733295714 env: Fix operation of 'make environ'
This was broken by the recent environment refactoring. Specifically:

$  make environ
scripts/Makefile.build:59: tools/environ/Makefile: No such file or directory
make[1]: *** No rule to make target 'tools/environ/Makefile'.  Stop.
make: *** [Makefile:1469: environ] Error 2

Fix this by updating the Makefile and adjusting the #include filesnames in
two C files.

3809e30273 Makefile: honor PYTHON configuration properly
On some systems `python` is `python3` (for instance, Archlinux). The
`PYTHON` variable can be used to point to `python2` to have a successful
build.

The use of `PYTHON` is currently limited in the Makefile and needs to be
extended in other places:

First, pylibfdt is required to be a Python 2 binding (binman imports
pylibfdt and is only compatible Python 2), so its setup.py needs to be
called accordingly. An alternative would be to change the libfdt
setup.py shebang to python2, but the binding is actually portable. Also,
it would break on system where there is no such thing as `python2`.

Secondly, the libfdt import checks need to be done against Python 2 as
well since the Python 2 compiled modules (in this case _libdft.so) can
not be imported from Python 3.

Note on the libfdt imports: "@if ! PYTHONPATH=tools $(PYTHON) -c 'import
libfdt'; then..." is probably simpler than the currently sub-optimal
pipe.

f291ce1298 spl: dm: Kconfig: split OF_CONTROL and OF_PLATDATA between SPL and TPL
For the RK3368, we want to use OF_PLATDATA in TPL, but full OF_CONTROL
in SPL: this requires the introduction of a new family of
configuration options to decouple SPL_OF_CONTROL and SPL_OF_PLATDATA
from TPL.

Consequently, Makefile.spl needs to be adjusted to test for these
configuration items through the $(SPL_TPL_) macro instead of
hard-coding the SPL variant.

e38ffc4267 fdt: Makefile: Build python libfdt library if needed
This is needed by binman and dtoc, so if those are being used, check that
the library is present and complain if not. Make sure that any error
appears on stderr so that buildman notices it.

This means that the fallback library (which uses fdtget) will not be used
anymore and swig will need to be installed to use binman / dtoc.

This affects any board which uses binman (currently sunxi and x86) or dtoc
(anything that uses CONFIG_SPL_OF_PLATDATA, currently some rockchip
boards).

1a12fdc461 Makefile: add rules to generate SPL FIT images
Some platforms require more complex U-Boot images than we can easily
generate via the mkimage command line, for instance to load additional
image files.
Introduce a CONFIG_SPL_FIT_SOURCE and CONFIG_SPL_FIT_GENERATOR symbol,
which can either hold an .its source file describing the image layout,
or, in the second case, a generator tool (script) to create such
a source file. This script gets passed the list of device tree files
from the CONFIG_OF_LIST variable.
A platform or board can define either of those in their defconfig file
to allow an easy building of such an image.

e391b1e64b Makefile: Fix linking with modern binutils
Since Binutils 1a9ccd70f9a7[1] u-boot will not link targets that set
CONFIG_SYS_TEXT_BASE=0 with the following error:

  LD      u-boot
arm-linux-gnueabi-ld.bfd: u-boot: Not enough room for program headers, try
 linking with -N
arm-linux-gnueabi-ld.bfd: final link failed: Bad value

The issue can be reproduced with the bad binutils and the rock2_defconfig
target.

This issue was also encountered by the powerpc kernel[2], with the fix
being to pass --no-dynamic-linker for linkers newer than 2.26 when this
flag was introduced. The option tells ld that the PIE or shared lib does
not need loaded program headers.

Ubuntu Zesty's Binutils 2.27.51.20161202 hits this error.

  UPD     cmd/license_data_gz.h

instead of the bare Make log:

cat ./Licenses/gpl-2.0.txt | gzip -9 -c | \

[2] Collect related code into the "cmd" directory

Prior to this commit, the license.h was created by tools/Makefile,
placed under the "include" directory, included from cmd/license.c,
and deleted by the top-level Makefile.  It is not a good idea to
scatter related code.

[3] Drop the fixed-malloc size LICENSE_MAX

Just allocate the minimum required size of buffer because we know
the size of the original gpl-2.0.txt.

[4] Fix more issues

Terminate the buffer with zero to prevent puts() from over-running.
Add "static" to do_license.

61304dbec3 cmd: add a new command "config" to show .config contents
This feature is inspired by /proc/config.gz of Linux.  In Linux,
if CONFIG_IKCONFIG is enabled, the ".config" file contents are
embedded in the kernel image.  If CONFIG_IKCONFIG_PROC is also
enabled, the ".config" contents are exposed to /proc/config.gz.
Users can do "zcat /proc/config.gz" to check which config options
are enabled on the running kernel image.

The idea is almost the same here; if CONFIG_CMD_CONFIG is enabled,
the ".config" contents are compressed and saved in the U-Boot image,
then printed by the new command "config".

The usage is quite simple.  Enable CONFIG_CMD_CONFIG, then run
 > config
from the command line interface.  The ".config" contents will be
printed on the console.

This feature increases the U-Boot image size by about 4KB (this is
mostly due to the gzip-compressed .config file).  By default, it is
enabled only for Sandbox because we do not care about the memory
footprint on it.  Of course, this feature is architecture agnostic,
so you can enable it on any board if the image size increase is
acceptable for you.

972188b3a8 x86: Use X86_16BIT_INIT instead of X86_RESET_VECTOR
Use this new option to control the location of 16-bit init. This will allow
us to place this in SPL if needed.

a1b6b0a9c1 arm: mvebu: Implement secure boot
The patch implements secure booting for the mvebu architecture.

This includes:
- The addition of secure headers and all needed signatures and keys in
  mkimage
- Commands capable of writing the board's efuses to both write the
  needed cryptographic data and enable the secure booting mechanism
- The creation of convenience text files containing the necessary
  commands to write the efuses

The KAK and CSK keys are expected to reside in the files kwb_kak.key and
kwb_csk.key (OpenSSL 2048 bit private keys) in the top-level directory.
