Commit 198cc26e49 (soc/amd/common/block/
psp/psp_gen2: use SMN access to PSP) changed how the PSP registers are
accessed. Since the new method doesn't need to rely on a MMIO base
address to be configured, the read will always be successful and so
soc_read_c2p38 doesn't need to return an error status and can directly
return the value instead.

The eSPI decode range defines aren't and shouldn't be used directly from
outside of the common AMD eSPI code which provides functions to abstract
the register access, so move the defines from amdblocks/espi.h to
espi_def.h inside the common AMD LPC/eSPI support directory to limit the
visibility. The special I/O range decode bits need to stay in
amdblocks/espi.h since those are used in the devicetree. Also update the
indentation in espi_def.h so that the defines line up properly.

Sabrina has more eSPI decode ranges than Picasso or Cezanne. Those
registers are however not in one block where it's easy to calculate the
addresses of a register from the index of the decode range. Within one
group of decode range registers it's still easy to calculate the
register address, so move the base address from within the macro to the
instantiation of the macro as a preparation for adding the support for
the additional ranges.

This patch adds support for power sequencing of the Nvidia GN3050 for
agah, which uses PCH GPIOs to control the 5 power rails required for
the GPU. The GPU is power sequenced on during mainboard
initialization, then it is enumerated on the PCI bus and its resources
are assigned. This GPU will be used in a sort of "hybrid graphics"
mode, therefore during finalization, since its PCI BARs are saved into
ACPI memory and the GPU is not required upon initial boot, the GPU is
power sequenced off.

The previous code required a bit too much effort to read. It also didn't

I find it difficult to constantly decode the registers when reading

The MT8186 platform fails to suspend due to premature wakeup by USB.
In MT8186, we use low level latch to keep USB wakeup signal. However,
hardware could latch a wrong signal if it debounces more than one time.
As a result, it would enable wakeup function too early.
To prevent this issue, we do the following modification:
- Delay about 100 us to enable wakeup function in kernel drivers [1].
- To guarantee 100 us is enough, we need to disable the USB debounce by
default in coreboot.
According to section register 0x404 and 0x420 in
"(CODA) MT8169_PERICFG_REG.xls" which is only for MediaTek internal use:
The current default value of debounce register for MT8186 USB IP0 and
IP1 is incorrect. The reason we add in coreboot is that the default
value should be correct when SoC is booting up.
This modification is only for MT8186. The subsequent SoCs will adjust
the wakeup function to correct register value by default.
