The Raydium ACPI entry currently provides a reset GPIO and an _ON/_OFF
method to the kernel. These are contradictory. The ownership of the GPIO
should be mutually exclusive between either the OS or the FW. Since we
have two methods exposed this causes the OS to reset the TS twice. Once
using the _ON method, and once using the GPIO. Additionally the _ON
method is waiting for 20ms after reset while the OS driver uses a 50ms
delay. The Raydium TS datasheet specifies 20ms for FW ready time, so the
OS driver is adding additional padding.
The reference design has a 32ms rise time on the reset line. So without
this patch, the OS tries to reset the TS using the _ON method and it
waits for 20ms. This is not enough time for the reset line to reach
high, let alone account for the FW ready time. The OS driver then tries
to reset the device by toggling the GPIO. It waits 50ms which is still
2ms less than required.
This CL removes the GPIO from being exported in the _CRS so the OS
driver won't try and reset the device. It also increases the reset delay
by 32ms to account for the rise time.
This isn't a complete fix. I think that the slow rise time is causing
some kind of metastability in the TS reset hardware. Using a script to
bind and unbind the TS driver, the TS device becomes unresponsive after
~200 iterations. The only way to reset the device is to power cycle.
The TS power is also not currently controlled by the power resource.
This means that we have no guarantee over when the reset line is
toggled. This will lead to issues while spending and resuming.

This change configures all missing pads in ramstage for trembyle
reference. This ensures that the state of all pads is set correctly
for the payload/OS. Also, all the pads for the platform are configured
in baseboard gpio table in ramstage to ensure that variants can
override any pads if required.

This change drops the pulls configured on override GPIOs as they
already have external pull-ups. Also, pads which are unused are
configured as PAD_NC.

This information is redundant since it's already specified in
baseboard/devicetree_trembyle.cb or baseboard/devicetree_dalboz.cb
domain 0 is still required because sconfig uses it as an identity anchor
to match devicetree and overridetree.

This is a copy of the mb/google/zork directory from the chromiumos
coreboot-zork branch. This was from commit 29308ac8606.
See https://chromium.googlesource.com/chromiumos/third_party/coreboot/+/29308ac8606/src/mainboard/google/zork
Changes:
* Minor changes to make the board build.
* Add bootblock.c.
* Modify romstage.c
* Removed the FSP_X configs from zork/Kconfig since they should be
set in picasso/Kconfig. picasso/Kconfig doesn't currently define the
binaries since they haven't been published. To get a working build
a custom config that sets FSP_X_FILE is required.
