The SPI ROM REQ/GNT pins are used in systems where the EC and the APU
share one flash chip to make sure that not both devices will try to
access the flash at the same time. The firmware running before the x86
cores are released from reset has likely already done this, but do it
again in bootblock just to be sure. The KBRST_L pin can be used to reset
the APU from the EC.

Commit 805956bce [soc/intel/cnl: Use Kconfig to disable HECI1]
moved HECI1 disablement out of mainboard devicetree and into SoC Kconfig,
but in doing so inadvertently disabled HECI1 for Puff-based boards which
previously had HECI1 enabled by default. To correct this, move the Kconfig
selection back into the mainboard Kconfig, and set defaults to match values
prior to refactoring in 805956bce.
Test: run menuconfig for boards google/{drallion,hatch,puff,sarien} and
ensure Disable HECI1 option defaults to selected for all except Puff.

The `reset` gpio is currently being consumed by the btusb kernel driver.
The functionality was added in https://crrev.com/c/3342774. The goal of
the patch was to reset the BT device when command timeouts occur. This
works, but it doesn't support the case where the BT device is having
problems with USB enumeration. In that case the device can't enumerate
so the driver can't help resetting the device.
If we instead switch to using an ACPI power resource, the kernel can
control the BT device's power. This is beneficial when the device is
having USB communication problems since the kernel will try and power
cycle the device.
We don't lose the ability to reset the device on command timeouts
either since `btusb_qca_cmd_timeout` will enqueue a USB port reset if
there is no `reset` GPIO. So win / win.
This results in the following power resource:
PowerResource (PR02, 0x00, 0x0000)
{
Method (_STA, 0, NotSerialized) // _STA: Status
{
Return (0x01)
}
Method (_ON, 0, Serialized) // _ON_: Power On
{
\_SB.CTXS (0x84)
Sleep (0x01F4)
}
Method (_OFF, 0, Serialized) // _OFF: Power Off
{
\_SB.STXS (0x84)
Sleep (0x0A)
}
}
I switched the device tree entry from using reset_gpio to enable_gpio
because the acpi_device_add_power_res method asserts the reset in the
_ON method unconditionally. This results in a small glitch on the line.
By using the enable_gpio we get the correct behavior.
I don't have a datasheet right now, so I just picked some values for the
reset timing. The kernel driver was using 200ms. We can revisit the
numbers when we get a datasheet.

of the way the autoupdate works, the CSE RO will not be updated during

Since the APIC bus isn't used since a long time and the IOAPIC and LAPIC
talk to each other via the system bus, there is no longer the
requirement that the IOAPIC IDs mustn't overlap with the LAPIC IDs that
start at 0 and end at CONFIG_MAX_CPUS - 1. The current Intel code uses 2
as the IOAPIC ID while most of their CPUs have more than 2 logical cores
resulting in the IOAPIC having the same ID as one of the LAPICs.
All chipsets in soc/amd use the defines for FCH_IOAPIC_ID and
GNB_IOAPIC_ID for initializing the IOAPIC register, writing both MADT
and IVRS ACPI tables and there's no MPTable support for those SoCs that
might also rely on those IDs being consistent.
This patch changes the definitions for FCH_IOAPIC_ID and GNB_IOAPIC_ID
from CONFIG_MAX_CPUS and CONFIG_MAX_CPUS + 1 to 0 and 1. This also makes
sure that the IOAPIC IDs still fit in 4 bits despite Cezanne having a
CONFIG_MAX_CPUS of 16 resulting in the IOAPIC IDs being larger than 4
bits with the old code. While the Cezanne FCH IOAPIC supports 8 bits of
IOAPIC IDs, this is non-standard.
TEST=AMD Mandolin and Google Liara still work.

Agah port 0 does not have a retimer so the port needs
to be configured for the SOC to handle Aux orientation flipping.

Alder Lake N has single memory controller with 64-bit bus width. Alder
Lake common meminit block driver considers bus width to be 128-bit and
populates the meminit data accordingly. By setting half_populated to
true, only the bottom half is populated.
Ideally, half_populated is used in platforms with multiple channels to
enable only one half of the channel. Alder Lake N has single channel,
and it would require for new structures to be defined in meminit block
driver for LPx memory configurations. In order to avoid adding new
structures, set half_populated to true. This has the same effect as
having single channel with 64-bit width.

The mainboards mc_apl{2,4,5,6} use VBOOT for verification and can be in
a recovery state for different reasons. In this case we still want the
MRC cache to be around to avoid the DRAM retraining on every boot.
This patch enables the Kconfig switch HAS_RECOVERY_MRC_CACHE which makes
the already available MRC recovery region in FMAP useable.
Test=Boot mc_apl2 in recovery mode and make sure the recovery MRC
cache is used.
