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 libpayload CBFS APIs are pretty old and clunky, primarily because of
the way the cbfs_media struct may or may not be passed in and may be
initialized inside the API calls in a way that cannot be passed back out
again. Due to this, the only real CBFS access function we have always
reads a whole file with all metadata, and everything else has to build
on top of that. This makes certain tasks like reading just a file
attribute very inefficient on non-memory-mapped platforms (because you
always have to map the whole file).
This patch isn't going to fix the world, but will allow a bit more
flexibility by bolting a new API on top which uses a struct cbfs_handle
to represent a found but not yet read file. A cbfs_handle contains a
copy of the cbfs_media needed to read the file, so it can be kept and
passed around to read individual parts of it after the initial lookup.
The existing (non-media) legacy API is retained for backwards
compatibility, as is cbfs_file_get_contents() (which is most likely what
more recent payloads would have used, and also a good convenience
wrapper for the most simple use case), but they are now implemented on
top of the new API.
TEST=Booted Oak, made sure that firmware screens and software sync

Extend the serial port description to include the input clock frequency
and a payload specific value.
Without the input frequency it is impossible for the payload to compute
the baud-rate divisor without making an assumption about the frequency.
This breaks down when the UART is able to support multiple input clock
frequencies.
Add the UART_PCI_ADDR Kconfig value to specify the unique PCI device
being used as the console UART. Specify this value as zero when the
UART is not on the PCI bus. Otherwise specify the device using bus,
device and function along with setting the valid bit.
Currently the only payload to consume these new fields is the EDK-II
CorebootPayloadPkg.
Testing on Galileo:
* Edit the src/mainboard/intel/galileo/Makefile.inc file:
* Add "select ADD_FSP_PDAT_FILE"
* Add "select ADD_FSP_RAW_BIN"
* Add "select ADD_RMU_FILE"
* Place the FSP.bin file in the location specified by CONFIG_FSP_FILE
* Place the pdat.bin files in the location specified by
CONFIG_FSP_PDAT_FILE
* Place the rmu.bin file in the location specified by CONFIG_RMU_FILE
* Build EDK2 CorebootPayloadPkg/CorebootPayloadPkgIa32.dsc to generate

* Testing is successful when CorebootPayloadPkg is able to properly

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.).

This change adds 'pivot' option to draw_bitmap. It controls the point of the
image based on which the image is positioned. For example, if a pivot is set
to the center of the image horizontally and vertically, the image is
positioned using pos_rel as the center of the image.
This feature is necessary, for example, to place a text image in the center
of the screen because each image has a different width depending on the
language.
This change also makes draw_bitmap accept both horizontal and vertical size.
If either of them is zero, the other non-zero value is used to derive the
size to keep the aspect ratio.
Specifying the height is necessary to keep font sizes the same when drawing
text images of different lengths.
draw_bitmap_direct is a variant of draw_bitmap and it draws an image using
a native coordinate and the original size (as opposed to the location and
the size relative to the canvas).
CL:303074 has real use cases.

Decompression is handled transparently within cbfs_get_file_content:
const char *name = "foo.bmp";
void *dst = cbfs_get_file_content(media, name, type, NULL);
To keep things consistent, a couple of API changes were necessary:
- cbfs_get_file_content always returns a copy of the data, even for
uncompressed files. It's the callers responsibility to free the
memory.
- same for cbfs_load_payload and cbfs_find_file.
- cbfs_load_optionrom doesn't take a "dest" argument anymore but always
returns a copy of the data, for compressed and uncompressed files.
Like with cbfs_get_file_content, the caller is responsible to free it.
It also decompresses based on extended file attributes instead of the
cbfs_optionrom subheader that libpayload specified but that (AFAIK)
nobody ever used, given that there's not even tooling for that.

Add the now coreboot standard MMIO read/write accessors that were
already defined for other architectures but not x86.
This leaves the old read/write{b,w,l} variants in place as was done
on the other architectures, presumably to support old payloads that
have not been updated.

This patch adds support for the LZ4 decompression algorithm to
libpayload. It's what all the cool kids are using for decompression
these days and has many interesting advantages over LZMA (and everything
else I know of): blazing fast decompression (20(!) times faster than
LZMA, twice as fast as LZO on my Cortex-A72), no memory requirements on
decompression, and possibly in-place decompression support. It pays for
that with a lower compression ratio (about 50% larger compressed size
than LZMA, 10% larger than LZO for an ARM64 Linux kernel binary), but
the boot time math still works in its favor for our IO speeds.
This patch only adds the raw decompression functions for use by external
payloads, we can later try integrating them in CBFS. It copies the
decompression code itself unmodified from the upstream LZ4 library at
github.com/Cyan4973/lz4 which will hopefully make it easy to update. The
frame format parsing is reimplemented since the upstream version looks
unnecessarily complex and unreadable for our needs.
