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
Ranga

Hi Ranga,
Are you using Intel RVP? Yes you should at least be able to see the PSE TSN
working if the PSE binary is included correctly (remember to include the
'unsigned' PSE binary from Intel), by turning on PSE TSN devices in
devicetree.cb:
device pci 1d.1 on end # Intel PSE Time-Sensitive Networking GbE 0
device pci 1d.2 on end # Intel PSE Time-Sensitive Networking GbE 1

Thanks,
Sheng
