Arthur Heymans 82aa8338c7 drivers/mrc_cache: Always generate an FMAP region
This automatically generates an FMAP region for the MRC_CACHE driver
which is easier to handle than a cbfsfile.

Adds some spaces and more comments to Makefile.inc to improve
readability.

Tested on Thinkpad x200 with some proof of concept patches.

Aaron Durbin facf14996c util/cbfstool: calculate cbfs file size for xip stages
The initial lookup for cbfs location for xip stages is implicitly
using the ELF size assuming it's relatively equivalent. However,
if the ELF that is being converted contains debug information or
other metadata then the location lookup can fail because the ELF is
considerably bigger than the real footprint.

Patrick Georgi 5d982d72be util/cbfstool: Add "expand" command to make CBFS span an fmap region
vboot images come with multiple regions carrying CBFS file systems. To
expedite hashing (from slow flash memory), the FW_MAIN_* regions are
truncated since they typically have pretty large unused space at the
end that is of no interest.
For test purposes it can be useful to re-engage that space, so add a
command that creates a new empty file entry covering that area (except
for the last 4 bytes for the master header pointer, as usual).

__packed to gain some consistency. In cbfstool we use compiler.h to
provide that where necessary.

The cross compiler I use doesn't provide __packed by itself, but liblz4
doesn't compensate for that. Therefore include compiler.h, and to avoid
adding dependencies to non-liblz4 code, do so through the command line.

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.

Patrick Georgi d9edb18037 util/cbfstool: Enable filling fmap regions with a given value
So far, cbfstool write, when used with the -u/-d options (to "fill
upwards/downwards") left the parts of the region alone for which there
was no new data to write.

When adding -i [0..255], these parts are overwritten with the given
value.

BUG=chromium:595715
BRANCH=none
TEST=cbfstool write -u -i 0 ... does the right thing (fill the unused
space with zeroes)

Ronald G. Minnich fa74e4705d cbfstool: set init_size for linux payloads.
We were not setting the init_size for linux payloads.
A proper value of init_size is required if the kernel
is x86_64.

This is tested in qemu and fixes the observed problem
that 974f221c84b05b1dc2f5ea50dc16d2a9d1e95eda and later would not
boot, and would in fact fail in head_64.S.

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.

Jonathan Neuschäfer 5de5458c2c util/cbfstool: Initialize elf_writer pointer to avoid crash
If some error happens in cbfs_payload_make_elf, the code jumps to "out",
and elf_writer_destroy(ew) is called. This may happen before an elf
writer is allocated.
To avoid accessing an uninitialized pointer, initialize ew to NULL;
elf_writer_destroy will perform no action in this case.
