Rizwan Qureshi b082670234 Kconfig: Add config for creating a second bootblock
Intel PCH/Southbridges have feature that it is possible
to have the southbridge/PCH look for the bootblock at a 64K or
128K/256K/512K/1MB (in case of newer SoCs) offset instead of
the usual top of flash.
Add configs to create a second bootblock and configure its size.

Nico Huber afc74cab6e Makefile.inc: Rewrite $(files-in-dir)
The `files-in-dir` macro is supposed to return all files (out of a
given set) that reside directly (non-recursive) in a given directory.
While the current solution worked splendidly, we can achieve the same
without recursive macros that look at each parent dir individually.

Beside providing better readability, this also fixes a future make
error, as make doesn't like the variable name ` ` anymore ;)

Julius Werner 99f4683adf Introduce bootblock self-decompression
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.

Julius Werner 1ca26664e6 Makefile.inc: Add separate bootblock.raw.elf with allocatable BSS
This patch moves the objcopy invocation that changes the bootblock's
section flags to make sure .data and .bss are preserved in the binary
image from the generation of bootblock.raw.bin into a separate
bootblock.raw.elf file. Some SoCs (like SDM845) like to have an ELF
rather than a raw binary as input to their masked ROM wrapper
generation script.

Also move those objcopy flags out into a variable because I'll need them
again in a later patch.

Martin Roth 3abdeb0af0 Makefile.inc: Ignore IASL empty resource template warnings
As I mention in the comment, this is valid ASL, which was added as
a warning with the comment "This would appear to be worthless in
real-world ASL code."  While code using empty resource templates
could probably be rewritten, this seems like an arbitrary choice
to generate this as a warning, since it's valid.

This gets rid of warnings such as this one:
dsdt.aml   2975:    Return (ResourceTemplate() {})
Warning  3150 - Empty Resource Template (END_TAG only)

Which is generated by this code in google/rambi/acpi/mainboard.asl:

  /* Only return interrupt if I2C1 is PCI mode */
  If (LEqual (\S1EN, 0)) {
    Return (^RBUF)
  }
  /* Return empty resource template otherwise */

Alex Thiessen 7bcd6ecea6 util/gitconfig: Use `make` in git hooks
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
Makefile.inc to gitconfig.sh.

Currently the only testing we had was 'what-jenkins-does' and
'make lint'. While the lint testing is suitable for developers,
the 'what-jenkins-does' target really isn't, as it was designed
specifically for testing on jenkins.

This adds the infrastructure for basic tests that are more suitable
for the developer. Extended tests and improvements will follow.

Add the coreboot-builds directories to .gitignore.

TODO:
- Save/restore .config
- Update test-abuild to use existing COREBOOT_BUILD_DIR variable

Youness Alaoui c4b4ff3b1f console/flashsconsole: Add spi flash console for debugging
If CONSOLE_SPI_FLASH config is enabled, we write the cbmem
messages to the 'CONSOLE' area in FMAP which allows us to grab the
log when we read the flash.

This is useful when you don't have usb debugging, and
UART lines are hard to find. Since a failure to boot would
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.

Julius Werner e91d170d21 Remove libverstage as separate library and source file class
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.

that it needs to convert a decimal to a binary in little endian

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.

The first attempt of providing a options-for-region function to call

can only be one instance which has to handle all of the files that may

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

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.

Martin Roth 888a98b872 payloads: add iPXE 'payload' build
We already have the ability to add a pxe rom to cbfs, but it needs to be
configured and built separately.

This moves the existing Kconfig options for PXE from device/Kconfig and
the top level Makefile.inc to payloads, and adds the option to download
and build iPXE as part of the coreboot build process.

This configures the serial output of iPXE to match coreboot's serial
port configuration by editing the .h files. iPXE doesn't give any
real build-time method of setting these configuration options.

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.

BUG=chrome-os-partner:48008
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
Falco without issues for good measure.
