2021-11-11mb/google/guybrush: Define ACPI Power Resources for FPMCUKarthikeyan Ramasubramanian
Currently all the power sequencing for FPMCU is done explicitly in different stages of coreboot. This can all be done by adding ACPI power resources for FPMCU and clean up the unused code. Here is the expected power sequence: PowerUp : Assert EN_PWR_FP -> 3 ms delay -> De-assert FPMCU_RST_ODL Shutdown : De-assert EN_PWR_FP -> Assert FPMCU_RST_ODL Reboot : Shutdown -> 200 ms delay -> PowerUp BUG=None TEST=Build and boot to OS in Guybrush. Ensure that the FP is able to unlock the system after the first login attempt. Ensure that the FP is able to wakeup the system. Observed that the power resource is added correctly in the FPMCU ACPI object Name (_PR0, Package (0x01) // _PR0: Power Resources for D0 { PR01 }) Name (_PR3, Package (0x01) // _PR3: Power Resources for D3hot { PR01 }) PowerResource (PR01, 0x00, 0x0000) { Method (_STA, 0, NotSerialized) // _STA: Status { Return (0x01) } Method (_ON, 0, Serialized) // _ON_: Power On { \_SB.CTXS (0x0B) \_SB.STXS (0x20) \_SB.STXS (0x0B) } Method (_OFF, 0, Serialized) // _OFF: Power Off { \_SB.CTXS (0x0B) \_SB.CTXS (0x20) } } Change-Id: I52322eaecf6961ff9a196ca9ab2d58b7d4599d4f Signed-off-by: Karthikeyan Ramasubramanian <kramasub@google.com> Reviewed-on: https://review.coreboot.org/c/coreboot/+/58705 Tested-by: build bot (Jenkins) <no-reply@coreboot.org> Reviewed-by: Raul Rangel <rrangel@chromium.org> Reviewed-by: Rob Barnes <robbarnes@google.com>

2021-10-15mb/google/guybrush/bootblock: drop redundant clearing of LPC decodesFelix Held
The writes were originally added due to being part of the initialization sequence in the reference code, but coreboot already has those registers cleared by the time we reach this part of the code, so we can drop these redundant writes.

This configures the bootblock portion of the PCIe GPIOs in the correct sequence to meet the power-on timings. Setting the PCIE Reset happens in coreboot instead of in the FSP. The Aux reset lines are anded with the PCIe RST line, so both have to be brought up together. On v1 of guybrush, the PCIe reset line also resets EC communication, so it must be brought up immediately on that version. BUG=b:184796302, b:184598323 TEST=Verify timings between GPIO init sections.

Currently variant_has_fpmcu() is called very early in bootblock, before eSPI is initialized. When checking CBI for its presence, that causes an error and nothing else can be read from CBI in bootblock. Moving it slightly later in bootblock doesn't hurt anything from a timing standpoint, and allows CBI to be read. BUG=None TEST=See CBI get read and the FPMCU field read correctly.
