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.

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.

Some remarks on the make process:
o We usually leave Ada specs (.ads files which are like c headers)
together with the bodies (implementations in .adb files) in one
directory. So we have to know, where they live.
o If there is no matching .adb an .ads is a valid source file and
we'll generate an object file from it.
o Object files need to have the same basename as their source files :-/
That's why we put them in build/<class>/ dirs now.
o We track dependencies by looking at the compiler output (.ali files
which accompany every .o). This way we don't need any gnatmake
magic, or even more complex, less portable tools.
For ADAFLAGS_common, I simply copied the CFLAGS_common whilst dropping
everything unsupported and adding sane warning options.
The set of language features is highly restricted (see gnat.adc). This
should suit the embedded nature of coreboot and helps proving absence
of runtime errors with SPARK.

than compiler-defined macros (like '#ifdef __arm__') and will make it
easier to write small, architecture-dependent differences in common code

technically incorrect in a world where every stage can run on a
different architecture, and merely kinda happened to work out for now).
Also remove a vestigal <arch/rules.h> from ARM64 which was no longer

We've seen an increasing need to reduce stack sizes more and more for
space reasons, and it's always guesswork because no one has a good idea
how little is too litte. We now have boards with 3K and 2K stacks, and
old pieces of common code often allocate large temporary buffers that
would lead to very dangerous and hard to detect bugs when someone
eventually tries to use them on one of those.
This patch tries improve this situation at least a bit by declaring 2K
as the minimum stack size all of coreboot code should work with. It
checks all function frames with -Wstack-usage=1536 to make sure we don't
allocate more than 1.5K in a single buffer. This is of course not a
perfect test, but it should catch the most common situation of declaring
a single, large buffer in some close-to-leaf function (with the
assumption that 0.5K is hopefully enough for all the "normal" functions
above that).
Change one example where we were a bit overzealous and put a 1K buffer
into BSS back to stack allocation, since it actually conforms to this
new assumption and frees up another kilobyte of that highly sought-after
verstage space. Not touching x86 with any of this since it's lack of
__PRE_RAM__ BSS often requires it to allocate way more on the stack than
would usually be considered sane.

The build system includes a bunch of files into verstage that
also exist in romstage - generic drivers etc.
These create link time conflicts when trying to link both the
verstage copy and romstage copy together in a combined configuration,
so separate "stage" parts (that allow things to run) from "library" parts
(that contain the vboot specifics).

We've decided that it is generally okay for coreboot to expect unaligned
accesses to work. Trying to find all instances of unaligned access
opportunities and working around them in software would be an
unsustainable whack-a-mole contest. Instead, architectures and boards
need to make sure they conform to this, which on ARM and ARM64 requires
setting up paging early in the bootblock.
Other architectures (x86, ARM64, MIPS) already generate code in this
manner. ARM still had an -mno-unaligned-access flag hanging around that
has been copied so many times its initial origin was lost in time
(probably U-Boot). Let's remove it for consistency between architectures
and to improve code generation.

TEST=Booted Jerry and Blaze. Looked at the disassembly for
timestamp_sync() and confirmed that it only gives you half as much eye
cancer as before (GCC still somehow insists on byte accesses when
zeroing fields which is very odd, but at least that terrible AND/OR mess
is gone). Measured a boot time increase of about 11ms on Jerry (mostly
faster timestamp and CBFS accesses). Could not test Storm because
despite our claimed abundance of test devices, every time I get one of
them it magically disappears again in less than a week.

Commit f69a99db (coreboot: x86: enable gc-sections) overrides
CFLAGS_x86_32, which looses (among other things) -m32, which
in turn breaks the build with the standard distro gcc on a
x86_64 machine.
Fix it by appending the new flags instead.

Add the build infrastructure and basic architectural support required
to build for targets using the MIPS architecture. This is sufficient
to run on a simulator, but will require the addition of some cache
maintenance and timer setup in order to run on real hardware.

This reverts the revert commit 5780d6f387
and fixes the build issue that cuased it to be reverted.
Verstage will host vboot2 for firmware verification.
It's a stage in the sense that it has its own set of toolchains,
compiler flags,
and includes. This allows us to easily add object files as needed. But
it's directly linked to bootblock. This allows us to avoid code
duplication for stage loading and jumping (e.g. cbfs driver) for the
boards
where bootblock has to run in a different architecture (e.g. Tegra124).
To avoid name space conflict, verstage symbols are prefixed with
verstage_.
TEST=Built with VBOOT2_VERIFY_FIRMWARE on/off. Booted Nyan Blaze.
