Martin Roth 03b9ecb2cf Makefile.inc: Add aliases for submodule updates to gitconfig target
Updating submodules seem to give people headaches, so this adds a pair
of git aliases to update them.

'git sup' updates the submodules to the latest versions, but leaves any
locally modified files.

'git sup-destroy' will remove the current submodules and re-initialize
them.  This deletes any local changes.

Nico Huber be5492aec0 Add minimal GNAT run time system (RTS)
Add a stripped-down version of libgnat. This is somehow comparable to
libgcc but for Ada programs. It's licensed under GPLv3 but with the
runtime library exception. So it's totally fine to link it with our
GPLv2 code and keep it under GPLv2.

Nico Huber 2e09d2b239 Make Ada a first class citizen
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.

Julius Werner f975e55dcd cbfs: Add "struct" file type and associated helpers
This patch adds functionality to compile a C data structure into a raw
binary file, add it to CBFS and allow coreboot to load it at runtime.
This is useful in all cases where we need to be able to have several
larger data sets available in an image, but will only require a small
subset of them at boot (a classic example would be DRAM parameters) or
only require it in certain boot modes. This allows us to load less data
from flash and increase boot speed compared to solutions that compile
all data sets into a stage.

Each structure has to be defined in a separate .c file which contains no
functions and only a single global variable. The data type must be
serialization safe (composed of only fixed-width types, paying attention
to padding). It must be added to CBFS in a Makefile with the 'struct'
file processor.

Patrick Georgi 513693ca3a build system: order per-region files to optimize placement success
Make sure that files with a fixed position are placed first (whose order
doesn't matter: either they collide or they don't), then all aligned
files (where we just hope that the right thing happens) and finally the
files with no further requirements (again, hope).
It's still a pretty good heuristic given a typical coreboot image.

The global sorting that happens earlier in the build flow will be
removed in the future to make room for per-region requirements.

Aaron Durbin bcbb205454 build system: add easier targetting of cbfstool options per region
The first attempt of providing a options-for-region function to call
to determining a file's cbfstool options would work, but it means there
can only be one instance which has to handle all of the files that may
need an override. That logic can be problematic in impelementation.

Instead, provide a mechanism to target cbfstool options for a given
CBFS region where the implementation is tightly coupled in the build
system to where the file as requested to be added to cbfs. This allows
there to be a base set of cbfstool options while more easily extending
arguments on specific regions.

Example which adds '-b 0x10000' only for the COREBOOT CBFS region:
cbfs-files-y += file.bin
file.bin-COREBOOT-cbfstool-opts := -b 0x10000

the tree didn't change, at least as far as the CBFS regions are
concerned.

Another option would be to synthesize the fmap related files from the
existing image, but that comes with other issues (eg. what about
updating images old enough that there is no fmap?) and is more complex,
so keep it simple, stupid for now.

Werner Zeh bc2d151b00 payload: Fix broken Linux kernel as payload
Commit 785a31d67e
(Makefile.inc: Move payload code to payloads/) breaks the usage of
Linux kernel as payload. The reason for it is that cbfs-files-y is
evaluated before payloads/external/Makefile.inc is sourced and as a
consequence ADDITIONAL_PAYLOAD_CONFIG is empty when it is used for
payload options. That leads to missing command line and initrd for
the kernel which in turn leads to kernel panic when it boots.
To avoid it, move the code which adds payload to cbfs completely to
payloads/extranal/Makefile.inc. This way, ADDITIONAL_PAYLOAD_CONFIG is
set right before the payload itself is added to cbfs-files-y.

I have tested this patch with a Linux kernel as well as with SeaBIOS as
payload on mc_tcu3 and it works. If someone sees impact to other
payloads just let me know.

Aaron Durbin 7f8afe0631 arch/x86: introduce postcar stage/phase
Certain chipsets don't have a memory-mapped boot media
so their code execution for stages prior to DRAM initialization
is backed by SRAM or cache-as-ram. The postcar stage/phase
handles the cache-as-ram situation where in order to tear down
cache-as-ram one needs to be executing out of a backing
store that isn't transient. By current definition, cache-as-ram
is volatile and tearing it down leads to its contents disappearing.
Therefore provide a shim layer, postcar, that's loaded into
memory and executed which does 2 things:

1. Tears down cache-as-ram with a chipset helper function.
2. Loads and runs ramstage.

Because those 2 things are executed out of ram there's no issue
of the code's backing store while executing the code that
tears down cache-as-ram. The current implementation makes no
assumption regarding cacheability of the DRAM itself. If the
chipset code wishes to cache DRAM for loading of the postcar
stage/phase then it's also up to the chipset to handle any
coherency issues pertaining to cache-as-ram destruction.

Julius Werner fffee873c8 Makefile: Add build-time overlap check for programs loaded after coreboot
On non-x86 platforms, coreboot uses the memlayout.ld mechanism to
statically allocate the different memory regions it needs and guarantees
at build time that there are no dangerous overlaps between them. At the
end of its (ramstage) execution, however, it usually loads a payload
(and possibly other platform-specific components) that is not integrated
into the coreboot build system and therefore cannot provide the same
overlap guarantees through memlayout.ld. This creates a dangerous memory
hazard where a new component could be loaded over memory areas that are
still in use by the code-loading ramstage and lead to arbitrary memory
corruption bugs.

This patch fills this gap in our build-time correctness guarantees by
adding the necessary checks as a new intermediate Makefile target on
route to assembling the final image. It will parse the memory footprint
information of the payload (and other platform-specific post-ramstage
components) from CBFS and compare it to a list of memory areas known to
be still in use during late ramstage, generating a build failure in case
of a possible hazard.

TEST=Built Oak while moving critical regions in the way of BL31 or the
payload, observing the desired build-time errors. Built Nyan, Jerry and

Julius Werner 09f2921b5d cbfs: Add LZ4 in-place decompression support for pre-RAM stages
This patch ports the LZ4 decompression code that debuted in libpayload
last year to coreboot for use in CBFS stages (upgrading the base
algorithm to LZ4's dev branch to access the new in-place decompression
checks). This is especially useful for pre-RAM stages in constrained
SRAM-based systems, which previously could not be compressed due to
the size requirements of the LZMA scratchpad and bounce buffer. The
LZ4 algorithm offers a very lean decompressor function and in-place
decompression support to achieve roughly the same boot speed gains
(trading compression ratio for decompression time) with nearly no
memory overhead.

For now we only activate it for the stages that had previously not been
compressed at all on non-XIP (read: non-x86) boards. In the future we
may also consider replacing LZMA completely for certain boards, since
which algorithm wins out on boot speed depends on board-specific
parameters (architecture, processor speed, SPI transfer rate, etc.).

BRANCH=None
BUG=None
TEST=Built and booted Oak, Jerry, Nyan and Falco. Measured boot time on
Oak to be about ~20ms faster (cutting load times for affected stages
almost in half).
