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.

It seems that gcc 6.3 at least is smart enough to warn about the _val

macro, but not smart enough to figure out that the default case is never
taken. This results in warnings such as the following:
pfx##hdr32[idx].field = _val; \

Avoid this by assigning _val = 0 in the default case, and asserting that

Fixes: 011dd93ca97a ("MIPS: Stop building position independent code")
Cc: Daniel Schwierzeck <daniel.schwierzeck@gmail.com>
Cc: Tom Rini <trini@konsulko.com>
Cc: u-boot@lists.denx.de
U-Boot has up until now built with -fpic for the MIPS architecture,
producing position independent code which uses indirection through a
global offset table, making relocation fairly straightforward as it
simply involves patching up GOT entries.
Using -fpic does however have some downsides. The biggest of these is
that generated code is bloated in various ways. For example, function
calls are indirected through the GOT & the t9 register:
8f998064 lw t9,-32668(gp)
0320f809 jalr t9
Without -fpic the call is simply:
0f803f01 jal be00fc04 <puts>
This is more compact & faster (due to the lack of the load & the
dependency the jump has on its result). It is also easier to read &
debug because the disassembly shows what function is being called,
rather than just an offset from gp which would then have to be looked up
in the ELF to discover the target function.
Another disadvantage of -fpic is that each function begins with a
sequence to calculate the value of the gp register, for example:
3c1c0004 lui gp,0x4
279c3384 addiu gp,gp,13188
0399e021 addu gp,gp,t9
Without using -fpic this sequence no longer appears at the start of each
function, reducing code size considerably.
This patch switches U-Boot from building with -fpic to building with
-fno-pic, in order to gain the benefits described above. The cost of
this is an extra step during the build process to extract relocation
data from the ELF & write it into a new .rel section in a compact
format, plus the added complexity of dealing with multiple types of
relocation rather than the single type that applied to the GOT. The
benefit is smaller, cleaner, more debuggable code. The relocate_code()
function is reimplemented in C to handle the new relocation scheme,
which also makes it easier to read & debug.
Taking maltael_defconfig as an example the size of u-boot.bin built
using the Codescape MIPS 2016.05-06 toolchain (gcc 4.9.2, binutils
2.24.90) shrinks from 254KiB to 224KiB.

It is annoying to have to set up and maintain two sets of toolchains, one
for buildman and one for moveconfig.
Adjust moveconfig to make use to buildman's toolchains. This should make
things easier.
One missing feature is the ability to specify the toolchain on the command
line with a special environment variable, e.g. CROSS_COMPILE_ARM. I'm not
sure if that is useful, but if it is it could be implemented in buildman.

The verify_header callback in kwbimage.c only verifies v0 headers checksum.
Running 'mkimage -l' on a v1 image gives the following misleading output:
GP Header: Size ae000000 LoadAddr 34160600
Implement support for v1 headers. For that, factor out the header checksum code
to a separate main_hdr_checksum_ok() routine. This routine relies on the fact
that the checksum field offset is the same in both v0 and v1 headers. With this
patch applied 'mkimage -l' correctly identifies the image:

# Add some 'imply' statements to Kconfig files

# Reprocess the defconfig files to see if we can drop some changes
git show --stat | ./tools/moveconfig.py -s -d -
# Update the commit, with fewer defconfig changes
