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.

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.

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

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.
