It's possible that some BARs are not got their resource successfully
mapped, e.g. when these BARs are too large to fit into the available
MMIO window.
Not assigned resources might be with base address as 0x0. During
global resource search, these not assigned resources should not be
picked up.
One example is MTRR calculation. MTRR calculation is based on global
memory ranges. An unmapped BAR whose base is left as 0x0 will be
mistakenly picked up and recognized as an UC range starting from 0x0.

coreboot uses TianoCore interchangeably with EDK II, and whilst the

commonly written as edk2.
coreboot builds edk2 directly from the edk2 repository. Whilst it
can build some components from edk2-platforms, the target is still
edk2.

We want to extend the vb2ex_hwcrypto APIs on the vboot side to allow
passing 0 for the data_size parameter to vb2ex_hwcrypto_digest_init()
(see CL:3825558). This is because not all use cases allow knowing the
amount of data to be hashed beforehand (most notable the metadata hash
for CBFS verification), and some HW crypto engines do not need this
information, so we don't want to preclude them from optimizing these use
cases just because others do.
The new API requirement is that data_size may be 0, which indicates that
the amount of data to be hashed is unknown. If a HW crypto engine cannot
support this case, it should return VB2_ERROR_EX_HWCRYPTO_UNSUPPORTED to
those calls (this patch adds the code to do that to existing HW crypto
implementations). If the passed-in data_size value is non-zero, the HW
crypto implementation can trust that it is accurate.
Also reduce a bit of the console spew for existing HW crypto
implementations, since vboot already logs the same information anyway.

When removing SD card from USB card reader, the USB MSC stack does
not detach the device immediately. Instead, the USB MSC stack calls
usbdisk_remove() and calls usb_msc_destroy() after several pollings.
It results in usbdisk_remove() being called twice.
Since the usbmsc_inst_t instance is freed after first usbdisk_remove()
call, the second call invokes an invalid usbmsc_inst_t instance and
causes exception in CPU.
This patch prevents usbdisk_remove() from being called twice by setting
usbdisk_created to zero.

DDR5 memory modules have two separate 32-bit channels (40-bit on ECC
memory modules), and the SPD info refers to one channel: the primary
bus width is 32 (or 40) bits and the "DIMM size" is halved. On Alder
Lake, there are 2 memory controllers with 4 32-bit channels each for
DDR5. FSP has 16 positions to store SPD data, some of which are only
used with LPDDR4/LPDDR5.
To try to make things less confusing, FSP abstracts the DDR5 channels
so that the configuration works like on DDR4. This is done by copying
each DIMM's SPD data to the other half-channel. Thus, fix the wrapper
parameters for DDR5 accordingly.
Tested on AlderLake-P DDR5 RVP (board ID 0x12), both DIMM slots now
function properly. Without this patch, only the top slot would work.

actually putting it in the public domain like the CC-C0 license does.
The use for this in coreboot is for unlicensable files - either blank

have the SPDX identifier to identify them as having no known copyright
for open source license compliance.
If CC-PDM-1.0 is ever included in the list of SPDX licenses, that would
probably fit better, but because the public domain mark isn't actually
a license, and because "public domain" isn't well defined, CC-PDM was
rejected as a SPDX identifier.

The EC used on zork uses a level high interrupt. This change configures
the polarity correctly.
The eSPI config is baked into RO verstage. The zork ToT build doesn't
use signed verstage since it's incompatible with the ToT version of
vboot. This means we can safely switch the keyboard IRQ polarity.
NOTE: Do not cherry pick this into the Zork firmware branch!

TEST=On morphius verify keyboard works as correctly and no spurious
interrupts are thrown on S0i3 resume. Also verified keyboard and mouse
work correctly in windows.

The default state for the IRQ lines when the eSPI controller comes out
of reset is high. This is because the IRQ lines are shared with the
other IRQ sources using AND gates. This means that in order to not cause
any spurious interrupts or miss any interrupts, the IO-APIC must use a
low polarity trigger.
On zork/guybrush/skyrim the eSPI IRQs are currently working as follows:
* On power on/resume the eSPI controller drives IRQ 1 high.
* eSPI controller gets configured to not invert IRQ 1.
* OS configures IO-APIC IRQ 1 as Edge/High.
* EC writes to HIKDO (Keyboard Data Out) which causes the EC to set IRQ1
high.
* eSPI controller receives IRQ 1 high, doesn't invert it, and leaves IRQ
1 as high. This results in missing the first interrupt.
* When the x86 reads from HIKDO, the EC deasserts IRQ1. This causes the
eSPI controller to set IRQ1 to low. We are now primed to catch the
next edge high interrupt. This is generally not a problem since the
linux driver will probe the 8042 with interrupts off.
On S3/S0i3 resume since the eSPI controller comes out of reset driving
the IRQ lines high, we trigger a spurious IRQ since the IO-APIC is
configured to trigger on edge high. This results in the 8042 controller
getting incorrectly marked as a wake trigger.
By configuring the IO-APIC to use low polarity interrupts, we no longer
lose the first interrupt. This also means we can use a level interrupt
to match what the EC actually asserts.
We use the `Interrupt` keyword instead of the `IRQ` keyword in the ACPI
because the linux kernel will ignore the level/polarity parameters
for the `IRQ` keyword and default to `edge/high. `Interrupt` doesn't
have this problem.
The PIC is not currently configured anywhere and it defaults to an
edge/high trigger. We could add some code to configure the PICs trigger
register, but I don't think we need the functionality right now.
For zork and guybrush, this change is a no-op. eSPI is configured in
verstage which is located in RO, and we have already locked RO for
these devices. We will need to figure out how to properly set the
`vw_irq_polarity` for these devices.

Verify keyboard works as expected and no interrupt storms are observed.
On morphius I verified keyboard and mouse work on windows as well.
