There were so many pitfalls that I wrote my own version of this even-
tually. This version is inspired by the procedure of Alex Thiessen[1].
Instead of generating a `build.h` on demand, we always generate a tem-
porary version that, if it differs from the current one, is added as
a dependency.
As we use .SECONDEXPANSION on the prerequisites, special care is taken
that we won't generate the file twice. As it would be too late to add
the dependency if we'd run `genbuild_h.sh` inside a recipe, we have
to run it through the `$(shell)` function. But that brings us to the
next issue: The make variables used by `genbuild_h.sh` are not expor-
ted to this shell like they would be in a recipe. So we export them
manually. We could also make these variables explicit parameters of
`genbuild_h.sh` instead.
An alternative to always creating the temporary `build.h` would be
to add a phony target as dependency instead, and finally calling
`genbuild_h.sh` again in case we need an update. But, um, we create
so many files anyway...

Masked ROMs are the silent killers of boot speed on devices without
memory-mapped SPI flash. They often contain awfully slow SPI drivers
(presumably bit-banged) that take hundreds of milliseconds to load our
bootblock, and every extra kilobyte of bootblock size has a hugely
disproportionate impact on boot speed. The coreboot timestamps can never
show that component, but it impacts our users all the same.
This patch tries to alleviate that issue a bit by allowing us to
compress the bootblock with LZ4, which can cut its size down to nearly
half. Of course, masked ROMs usually don't come with decompression
algorithms built in, so we need to introduce a little decompression stub
that can decompress the rest of the bootblock. This is done by creating
a new "decompressor" stage which runs before the bootblock, but includes
the compressed bootblock code in its data section. It needs to be as
small as possible to get a real benefit from this approach, which means
no device drivers, no console output, no exception handling, etc.
Besides the decompression algorithm itself we only include the timer
driver so that we can measure the boot speed impact of decompression. On
ARM and ARM64 systems, we also need to give SoC code a chance to
initialize the MMU, since running decompression without MMU is
prohibitively slow on these architectures.
This feature is implemented for ARM and ARM64 architectures for now,
although most of it is architecture-independent and it should be
relatively simple to port to other platforms where a masked ROM loads
the bootblock into SRAM. It is also supposed to be a clean starting
point from which later optimizations can hopefully cut down the
decompression stub size (currently ~4K on RK3399) a bit more.
NOTE: Bootblock compression is not for everyone. Possible side effects
include trying to run LZ4 on CPUs that come out of reset extremely
underclocked or enabling this too early in SoC bring-up and getting
frustrated trying to find issues in an undebuggable environment. Ask
your SoC vendor if bootblock compression is right for you.

As the code was moved from the Makefile.inc to a separate file in
commit 9ab8ae6a (util/gitconfig: Make gitconfig a bash script),`$(MAKE)`
was replaced by `remake`, introducing dependency on this tool which is
basically a `make` with debugging capabilities. Many developers don't
have `remake` installed, leading to pre-commit hooks being not executed
properly. Apparently this was an unintentional change.
Furthermore, special treatment of `make` tool via the `%MAKE%`
substitution performed during hooks' deployment is still desired. Use
case is calling `remake gitconfig` to set `remake` as the `make` tool in
the hooks. To accomplish this, add a parameter that is passed from the

require a hardware flasher anyways, we can get the log
at the same time.
This feature should only be used when no alternative is
found and only when we can't boot the system, because
excessive writes to the flash is not recommended.
This has been tested on purism/librem13 v2 and librem 15 v3 which
run Intel Skylake hardware. It has not been tested on other archs
or with a driver other than the fast_spi.

The ramstage-c-ccopts variable needs to be double dereferenced
for the cbfs-files-processor-struct handler so all the ccopts
are included since the ramstage-c-ccopts is fully constructed
later by another function. Without this not all the flags
are present on the command line.

Add a Makefile.inc, based on sconfig's, to use the _shipped variants
so that the build doesn't have to generate them with flex & bison.
The GENPARSER check is inactive, and will be updated in the next
commit.
Add the c_shipped & h_shipped files for the current .l & .y files.

With COREBOOT_BUILD_DIR set, nvramcui & coreinfo were getting built
in the wrong location, causing those builds to fail.
Also, because they were built in the wrong location, the build failures
were not detected by jenkins which was looking for the junit.xml files
under the payloads directory.

In builds without CONFIG_VBOOT_SEPARATE_VERSTAGE, verstage files are
linked directly into the bootblock or the romstage. However, they're
still compiled with a separate "libverstage" source file class, linked
into an intermediate library and then linked into the final destination
stage.
There is no obvious benefit to doing it this way and it's unclear why it
was chosen in the first place... there are, however, obvious
disadvantages: it can result in code that is used by both libverstage
and the host stage to occur twice in the output binary. It also means
that libverstage files have their separate compiler flags that are not
necessarily aligned with the host stage, which can lead to weird effects
like <rules.h> macros not being set the way you would expect. In fact,
VBOOT_STARTS_IN_ROMSTAGE configurations are currently broken on x86
because their libverstage code that gets compiled into the romstage sets
ENV_VERSTAGE, but CAR migration code expects all ENV_VERSTAGE code to
run pre-migration.
This patch resolves these problems by removing the separate library.
There is no more difference between the 'verstage' and 'libverstage'
classes, and the source files added to them are just treated the same
way a bootblock or romstage source files in configurations where the
verstage is linked into either of these respective stages (allowing for
the normal object code deduplication and causing those files to be
compiled with the same flags as the host stage's files).
Tested this whole series by booting a Kevin, an Elm (both with and
without SEPARATE_VERSTAGE) and a Falco in normal and recovery mode.

We rely on gnu make, so we can expect the jobserver to be around in
parallel builds, too. Avoids some make warnings and slightly speeds up
the build if those sub-makes are executed (eg for arm-trusted-firmware
and vboot).

Without this motherboards that requires a non zero timeout for ps2
keyboards on SeaBIOS don't build when CONFIG_UPDATE_IMAGE is set.
An alternative way to achieve this file would be to include a cbfsfile
instead of calling cbfstool. That way the file gets updated/added both
both image update and regular build. A difficulty of that approach is
that it needs to convert a decimal to a binary in little endian
representation, which is not a trivial thing to do in a Makefile.

It takes a long time for no gain: We don't need to update the
submodules, we don't need to fetch the revision, we don't need to find
the compilers, when all we want to do is to manipulate the .config file
or clean the build directory.

Different compiler versions use a different C language standard by
default.
GCC 4.9 uses GNU89 by default [1], while GCC 5.x uses GNU11 [2].
The discussion on the mailing list in thread *[RFC] Setting C99 by
default* [3] resulted in the preference of C11, which results in build
errors.
So explicitly set it to GNU11, which is also what the current coreboot
toolchain with GCC 5.3 is using.
