One of the main functions performed by the FSP GOP driver is to modify
the ATOMBIOS tables (part of the VBIOS) in memory based on the display
output configuration. This device-specific modified VBIOS can be cached
in a FMAP region specific for that purpose, then loaded into memory
instead of the "generic" VBIOS, saving the ~130ms execution time of the
GOP driver.
As this approach only works when no pre-OS display output is needed,
limit its use to ChromeOS builds, with the GOP driver enabled, and
not booting in either recovery or developer modes.
SoCs supporting this feature will need to selectively run the FSP GOP
driver as needed, using the same criteria used here to determine
whether to load the VBIOS from CBFS or from the FMAP cache.
Boards utilizing this feature will need to add a dedicated FMAP region
with the appropriate name/size, and select the required Kconfig options.

When enable_gpio is used as active low output, the _STA returns
incorrect value.
Also, simply the logic for _STA method.
When enable pin is used for _STA:
| polarity | tx value| get_tx_gpio() | State |
| active high | 0 | 0 | 0 |
| active high | 1 | 1(active) | 1 |
| active low | 0 | 1(active) | 1 |
| active low | 1 | 0 | 0 |
When reset pin is used for _STA:
| polarity | tx value| get_tx_gpio() | State |
| active high | 0 | 0 | 1 |
| active high | 1 | 1(active) | 0 |
| active low | 0 | 1(active) | 0 |
| active low | 1 | 0 | 1 |
Generated _STA method:
Ex: for using active low power enable GPIO pin GPPC_H17:
Method (_STA, 0, NotSerialized) // _STA: Status
{
Local0 = \_SB.PCI0.GTXS (0x5C)
Local0 ^= One
Return (Local0)
}
TEST=Check the SSDT when booted to OS.

This includes mb/dell/e6400 and ec/dell/mec5035, the latter being
the EC on the E6400. Also link to my repo containing research
and documentation I wrote for the MEC5035.
