[coreboot] PSE devices enumeration in corevoot

[Rao G]

Hi All,

Did anybody work on Elkhart Lake that comes with PSE Firmware?
I don't see any devices getting enumerated which are under PSE I2C,UART,
Gbe,TSN

The logs shows

PSE Firmware Status is A138 read from address FE400034
BIOS: PSE FW is loaded and running

Looks like FSP is disabling PSE devices to enumerate

Is this binary enough for coreboot? PSE_FW.bin

Appreciate any pointers that would help to enumerate PSE devices in EFI
Shell

Thanks
