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.

3 out of 4 architectures currently zero out the payload BSS in early
assembly code, which is pointless since the code loading the payload has
already done that (with a more efficient memset). ARM64 has never had
any code like this and can run just fine without it. This also defeats
the new optimization of moving the heap out of the BSS, since all three
implementations assume that everything between _edata and _end is BSS.
We should just take this out.

Allocating a 15980-byte scratchpad on the stack when your default stack
size is set to 16KB is really not a great idea. We're regularly
overflowing into the end of our heap when using LZMA in libpayload, and
just happen not to notice it because the heap rarely gets filled up all
the way. Of course, since we always *have* a heap in libpayload, the
much saner solution is to just use it directly to allocate the
scratchpad rather than accidentally grow backwards into it anyway.

The ARM64 MMU code maintains a list of used ranges, to avoid mapping the
DMA buffer over the coreboot tables and things like that. Unfortunately,
the overlap with ranges in that list is checked with
(start1 >= start2 && start1 <= end2) || (end1 >= start2 && end1 <= end2)
which is not a full overlap check and misses the case where the second
region is completely contained within the first. This patch replaces
that code with a properly vetted primitive from Stack Overflow.

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.

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.

* 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

* Place the rmu.bin file in the location specified by CONFIG_RMU_FILE
* Build EDK2 CorebootPayloadPkg/CorebootPayloadPkgIa32.dsc to generate

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.

This series of patches attempts to update all of the external payload
makefiles to be as similar as possible.
- Add .git to the git repo URL to show that it's a git repo.
- Use the common checkout, fetch, and clone ($(project dir)) targets
- Add TAG-y and NAME-y variables - just with origin/master for now.
Stable will be added shortly.
- Make sure all phony targets are in .PHONY

drivers/usb/xhci.c and drivers/usb/ehci.c both require arch/barrier.h.
barrier.h is present for x86, arm, and arm64, but not for mips. This
is generating a build error after enabling USB by default on libpayload.
I believe that this slipped through the buiders due to them not getting
cleaned fully. It was caught in the coverity scan and when setting up

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.

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).
