f3d8f7dd73 Allow providing default environment from file
Modifying the default environment via CONFIG_EXTRA_ENV_SETTINGS is
somewhat inflexible, partly because the cpp language does not allow
appending to an existing macro. This prevents reuse of "environment
fragments" for different boards, which in turn makes maintaining that
environment consistently tedious and error-prone.

This implements a Kconfig option for allowing one to define the entire
default environment in an external file, which can then, for example, be
generated programmatically as part of a Yocto recipe, or simply be kept
in version control separately from the U-boot repository.

948071bab4 Makefile: Disable stack-usage check for ARC
With the most recent tools for ARC (arc-2017.09) in case of
"naked" function compiler throws a warning:
---------------------------------->8-----------------------------
board/synopsys/hsdk/hsdk.c: In function 'hsdk_core_init_f':
board/synopsys/hsdk/hsdk.c:345:1: warning: stack usage computation not supported for this target
 }
 ^
---------------------------------->8-----------------------------

That happens because the compiler doesn't handle "naked" functions
as a special case where stack calculation shouldn't be done.

But for now until this is fixed in GCC to get clean buildman output
we're disabling stack-usage check for ARC.

See https://lists.denx.de/pipermail/u-boot/2018-April/324455.html
for more background.

1022807c21 Makefile: Don't mess with .text section location for selected arches
Most of architectures have .text section situated in the very beginning
of U-Boot binary and thus it is very logical that CONFIG_SYS_TEXT_BASE
is used on final linkage step to specify where U-Boot gets linked to.

For that we pass the following construction to the LD:
---------------------------->8-----------------------
xxx-ld ...  -Ttext $(CONFIG_SYS_TEXT_BASE) ...
---------------------------->8-----------------------

But there could be exceptions. For example:
 1. In case of ARCv2 we want to put vectors table in its own section
    .ivt in front of .text section which means we need either add an
    offset to CONFIG_SYS_TEXT_BASE to compensate for .ivt or don't
    pass "-Ttext" to the LD at all and specify link base in linker
    script directly.

 2. Some architectures even though have .text section in the very
    beginning of the U-Boot image still use different symbols to
    specify link-base:
       * NIOS2: CONFIG_SYS_MONITOR_BASE (which I really like because
         that exactly what makes sense - where out image starts but not
         beginning of its .text section which just happened to match the
         whole image beginning)
       * EXTENSA: CONFIG_SYS_TEXT_ADDR
       * X86: Which doesn't use CONFIG_SYS_MONITOR_BASE in case of EFI
         otherwise sets explicit link base in u-boot.lds

I think that's good to allow for flexibility and don't require each and
every architecture or even platform to specify CONFIG_SYS_TEXT_BASE as well
as use it to set .text section location.

So let's only pass "-Ttext xxx" for those architectures who don't set
link-base explicitly in their linker scripts.

This patch iaddresses comments for previously sent
https://patchwork.ozlabs.org/patch/867540/.

f2faffecb0 binman: tegra: Convert to use binman
Update tegra to use binman for image creation. This still includes the
current Makefile logic, but a later patch will remove this. Three output
files are created, all of which combine
SPL and U-Boot:

   u-boot-tegra.bin        - standard image
   u-boot-dtb-tegra.bin    - same as u-boot-tegra.bin
   u-boot-nodtb-target.bin - includes U-Boot without the appended device tree

The latter is useful for build systems where the device is appended later,
perhaps after being modified.

dd2081a8e4 Makefile: Correct SPL/TPL/DTB build race condition
When building on a multi-core machine for an SPL-enabled board that
also uses CONFIG_OF_EMBED, the following error can be encountered
due to a race condition:

  make[3]: *** No rule to make target 'spl/dts/dt.dtb.o', needed by
    'spl/dts/built-in.o'.  Stop.
  ../scripts/Makefile.spl:364: recipe for target 'spl/dts' failed
  make[2]: *** [spl/dts] Error 2
  make[2]: *** Waiting for unfinished jobs....

A reliable way to trigger this race condition is to add "sleep 60" to
the end of the "arch-dtbs" rule's recipe in "dts/Makefile" and to build
U-Boot against a board which uses the CONFIG_OF_EMBED and CONFIG_SPL
options using "make -j8" or a similar command.

This commit corrects this race condition via the use of CONFIG_OF_EMBED
in the same way that commit 3c00a2c8b5 ("Makefile: Correct dependency
race condition with TPL") and commit 054b3a1e80 ("dm: Makefile: Build
of-platdata before SPL") use CONFIG_OF_SEPARATE.

d6a0c78a4e pylibfdt: compile pylibfdt only when dtoc/binman is necessary
Currently, pylibfdt is always compiled if swig is installed on your
machine.  It is really annoying because most of targets (excepts
x86, sunxi, rockchip) do not use dtoc or binman.

"checkbinman" and "checkdtoc" are wrong.  It is odd that the final
build stage checks if we have built necessary tools.  If your platform
depends on dtoc/binman, you must be able to build pylibfdt.  If swig
is not installed, it should fail immediately.

I added PYLIBFDT, DTOC, BINMAN entries to Kconfig.  They should be
property select:ed by platforms that need them.  Kbuild will descend
into scripts/dtc/pylibfdt/ only when CONFIG_PYLIBFDT is enabled.

15b97f5c5e pylibfdt: move pylibfdt to scripts/dtc/pylibfdt and refactor makefile
The pylibfdt is used by dtoc (and, indirectly by binman), but there
is no reason why it must be generated in the tools/ directory.

Recently, U-Boot switched over to the bundled DTC, and the directory
structure under scripts/dtc/ now mirrors the upstream DTC project.
So, scripts/dtc/pylibfdt is the best location.

I also rewrote the Makefile in a cleaner Kbuild style.

The scripts from the upstream have been moved as follows:

  lib/libfdt/pylibfdt/setup.py -> scripts/dtc/pylibfdt/setup.py
  lib/libfdt/pylibfdt/libfdt.i -> scripts/dtc/pylibfdt/libfdt.i_shipped

The .i_shipped is coped to .i during building because the .i must be
located in the objtree when we build it out of tree.

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.
