Currently it's not possible to add multiple graphics driver into
one coreboot image. This patch series will fix this issue by providing
a single API that multiple graphics driver can use.
This is required for platforms that have two graphic cards, but
different graphic drivers, like Intel and Aspeed on server platforms or
Intel and Nvidia on consumer notebooks.
The goals are to remove duplicated fill_fb_framebuffer(), to advertise
multiple independent framebuffers in coreboot tables, and better
runtime/build time graphic configuration options.
Add an implementation in edid_fill_fb that supports registering
multiple framebuffers, each with its own configuration.
As the current code is only compiled for a single graphics driver
there's no change in functionality.

Configure the CFG2 register to set the latency to <64us in order
to ensure the L1 exit latency is consistent across devices and that
L1 ASPM is always enabled.
This moves the setup code from device init to device enable so it
executes before coreboot does ASPM configuration, and removes the
call to pci_dev_init() as that is just for VGA Option ROMs.
BUG=b:173207454
TEST=Verify the device and link capability and control for L1:
DevCap: Latency L1 <64us
LnkCap: Latency L1 <64us
LnkCtl: ASPM L1 Enabled

Currently this XHCI driver assumes the PCH XHCI controller, but the TCSS
or North XHCI block has a similar enough PCI MMIO structure to make this
code mostly reusable.
1) Rename everything to drop the `pch_` prefix
2) xhci_update_wake_event() now takes in a pci_devfn_t for the XHCI
controller
3) soc_get_xhci_usb_info() also now takes a pci_devfn_t for the XHCI
controller

2. Replace "jsl" with "ehl"
3. Replace "jslrvp" with "ehlcrb"
4. Remove unwanted SPD file, add empty SPD as placeholder
6. Empty romstage_fsp_params.c, to fill it later with SOC specific
config
7. Empty GPIO configurations, to be filled as per board
8. Empty memory.c configurations, to be filled as per board
9. Add board support namely BOARD_INTEL_ELKHARTLAKE_CRB
10. Replace jslrvp variant with ehlcrb variant

so we can be absolutely sure there is no other connection.

(Re)configure various pads found by dissecting a dead board and vendor
firmware, as well as the BMC firmware:
- GPP_B14: input connected to jumper JBR1 - could be used to implement
"BIOS Recovery" ("Top-Block Swap") functionality; external pull-up
- GPP_C20: output to BMC alert CPU_THROTTLED# - can be used to notify
the BMC about a thermal throttling event. Not implemented in vendor
firmware.
- GPP_C23: input connected to the CPU's CATERR# output; external pull-up
Not actively used by vendor firmware.
- GPP_D1: output connected to on-board and front panel power LEDs
- GPP_D18: output connected to PERST# of both CPU PCIe Slots. Can be
used for testing/debugging only, since it resets both slots at once.
Not actively used by vendor firmware.
- GPP_D19: output connected to PERST# of both PCH PCIe Slots. Can be
used for testing/debugging only, since it resets both slots at once.
Not actively used by vendor firmware.
- GPP_D22: input connected to the BMC enable/disable jumper JPB1; Will
be used later in CB:48096 and CB:48097; external pull-up
- GPP_G0 - GPP_G3: dedicated/integrated CPU switching; probably not
useful, since the IGD is not connected to any ports on this board.
External pulls ensure correct function of a dGPU even without driving
the gpios. Not used by vendor firmware.
- GPP_G12 - GPP_G16: inputs for binary SKU_ID; external pulls
- GPP_G20: PWRFAIL# input from JPI2C1 (pin 3); external pull-up; Not
used by vendor firmware.
Also add comments for documentation. While at it, mark ME-owned pads as
reserved.

This patch addresses the same problem as CB:48429, but hopefully this
time correctly. Since the mcache is not guaranteed to be available on
the first CBFS lookup for some special cases, we can no longer treat it
as a one-time fire-and-forget initialization. Instead, we test
cbd->mcache_size to check if the mcache has been initialized yet, and
keep trying on every lookup if we don't find it the first time.
Since the mcache is a hard requirement for TOCTOU safety, also make it
more clear in Kconfig that configurations known to do CBFS accesses
before CBMEM init are incompatbile with that, and make sure we die()
rather than do something unsafe if there's a case that Kconfig didn't
catch.

This change reorganizes FMAP for volteer to make use of the lower
16MiB of the SPI flash for RW_SECTION_A and RW_MISC in addition to
RW_LEGACY. This is now possible because TGL supports memory mapping of
BIOS region greater than 16MiB.
Following changes are made in chromeos.fmd as part of this:
1. Move RW_SECTION_A and RW_MISC to lower 16MiB.
2. Reduce size of RW_LEGACY to 2MiB since we longer need to use it as
a placeholder in the lower half of the SPI flash.
3. Reduce size of RW_ELOG to 4KiB as coreboot does not support a
larger region for ELOG.
4. Increase WP_RO to 8MiB to allow larger space for firmware
screens. GBB size is thus increased to 448KiB.

This change enables caching for extended BIOS region.
Currently, caching is enabled for the standard BIOS region
upto a maximum of 16MiB using fast_spi_cache_bios_region,
used the same function to add the support for caching for
extended BIOS region as well.
Changes include:
1. Add a new helper function fast_spi_cache_ext_bios_window()
which calls fast_spi_ext_bios_cache_range() which calls
fast_spi_get_ext_bios_window() to get details about the
extended BIOS window from the boot media map and checks for
allignment and set mtrr.
2. Make a call to fast_spi_cache_ext_bios_region() from
fast_spi_cache_bios_region ().
3. Add new helper function fast_spi_cache_ext_bios_postcar()
which does caching ext BIOS region in postcar similar to 1.
4. If the extended window is used, then it enables caching

This change enables support for configuration of extended BIOS
region decode window. This configuration needs to be performed
as early as possible in the boot flow. This is required to
ensure that any access to the SPI flash region below 16MiB in
coreboot is decoded correctly. The configuration for the extended
BIOS window if required is done as part of fast_spi_early_init().
Changes include:
1. Make a call to fast_spi_enable_ext_bios() before the bus master
and memory space is enabled for the fast SPI controller.
2. Added a helper function fast_spi_enable_ext_bios() which calls
fast_spi_get_ext_bios_window() to get details about the extended
BIOS window from the boot media map.
3. Depending upon the SPI flash device used by the mainboard and
the size of the BIOS region in the flashmap, this function will
have to perform this additional configuration only if the BIOS
region is greater than 16MiB
4. Adddditionally, set up the general purpose memory range
registers in DMI.

This change allows configuring the General Purpose
Memory Range(GPMR) register in BIOS to set up the decoding in DMI.
This driver provides the following functionality:
1. Add a helper function dmi_enable_gpmr which takes as input base,
limit and destination ID to configure in general purpose memory range
registers and then set the GPMR registers in the next available
free GMPR and enable the decoding.
2. Add helper function get_available_gpmr which returns available free
GPMR.
3. This helper function can be utilized by the fast SPI driver to
configure the window for the extended BIOS region.

This change adds details about the memory map windows to translate
addresses between SPI flash space and host address space to coreboot
tables. This is useful for payloads to setup the translation using the
decode windows already known to coreboot. Until now, there was a
single decode window at the top of 4G used by all x86
platforms. However, going forward, platforms might support more decode
windows and hence in order to avoid duplication in payloads this
information is filled in coreboot tables.
`lb_spi_flash()` is updated to fill in the details about these windows
by making a call to `spi_flash_get_mmap_windows()` which is
implemented by the driver providing the boot media mapping device.

This change enables support for a custom boot media device in fast SPI
controller driver if the platform supports additional decode window
for mapping BIOS regions greater than 16MiB. Following new Kconfigs
are added:
1. FAST_SPI_SUPPORTS_EXT_BIOS_WINDOW: SoC can select this to indicate
support for extended BIOS window.
2. EXT_BIOS_WIN_BASE: If FAST_SPI_SUPPORTS_EXT_BIOS_WINDOW is
selected, this provides the base address of the host space that is
reserved for mapping the extended window.
3. EXT_BIOS_WIN_SIZE: If FAST_SPI_SUPPORTS_EXT_BIOS_WINDOW is
selected, this provides the size of the host space reserved for
mapping extended window.
If platform indicates support for extended BIOS decode window,
cbfstool add command is provided additional parameters for the decode
window using --ext-win-base and --ext-win-size.
It is the responsibility of the mainboard fmap author to ensure that
the sections in the BIOS region do not cross 16MiB boundary as the
host space windows are not contiguous. This change adds a build time
check to ensure no sections in FMAP cross the 16MiB boundary.
Even though the platform supports extended window, it depends upon the
size of BIOS region (which in turn depends on SPI flash size) whether
and how much of the additional window is utilized at runtime. This
change also provides helper functions for rest of the coreboot
components to query how much of the extended window is actually
utilized.

There have been a few issues with the new CBFS mcache code in stages
after romstage, where the mcache resides in CBMEM. In a few special
cases the stage may be doing a CBFS lookup before calling
cbmem_initialize(). To avoid breaking those cases, this patch makes the
CBFS code fall back to a lookup from flash if CBMEM hasn't been
reinitialized yet in those stages.

cbmem_online() always returns 1 in stages after romstage. However, CBMEM
isn't actually immediately available in those stages -- instead, it will
only become available when cbmem_initialize() is called. That usually
happens very early in the stage, but there are still small amounts of
code running beforehand, so it is useful to reflect this distinction.

This change updates the translated region device (xlate_region_dev) to
support multiple translation windows from the 1st address space to
2nd address space. The address spaces described by the translation
windows can be non-contiguous in both spaces. This is required so that
newer x86 platforms can describe memory mapping of SPI flash into
multiple decode windows in order to support greater than 16MiB of
memory mapped space.
Since the windows can be non-contiguous, it introduces new
restrictions on the region device ops - any operation performed on the
translated region device is limited to only 1 window at a time. This
restriction is primarily because of the mmap operation. The caller
expects that the memory mapped space is contiguous, however, that is
not true anymore. Thus, even though the other operations (readat,
writeat, eraseat) can be updated to translate into multiple operations
one for each access device, all operations across multiple windows are
prohibited for the sake of consistency.
It is the responsibility of the platform to ensure that any section
that is operated on using the translated region device does not span
multiple windows in the fmap description.
One additional difference in behavior is xlate_region_device does not
perform any action in munmap call. This is because it does not keep
track of the access device that was used to service the mmap
request. Currently, xlate_region_device is used only by memory mapped
boot media on the backend. So, not doing unmap is fine. If this needs
to be changed in the future, xlate_region_device will have to accept a
pre-allocated space from the caller to keep track of all mapping
requests.
