Subrata Banik has uploaded this change for review. ( https://review.coreboot.org/c/coreboot/+/85526?usp=email )
Change subject: soc/intel/pantherlake: Fix UFS ACPI inclusion in southbridge.asl

soc/intel/pantherlake: Fix UFS ACPI inclusion in southbridge.asl
This patch corrects the conditional inclusion of the `ufs.asl` file in
the southbridge ACPI configuration.
Previously, the inclusion of `ufs.asl` was incorrectly dependent on the
`MAINBOARD_USES_IFD_GBE_REGION` Kconfig option. This prevented the UFS
ACPI entry from being included in the DSDT when
`MAINBOARD_USES_IFD_GBE_REGION` was disabled, causing issues with
booting from UFS media.
This commit fixes the issue by ensuring that `ufs.asl` is included
based on the `SOC_INTEL_PANTHERLAKE_U_H` Kconfig option, which correctly
reflects the presence of UFS hardware.
This change ensures that the UFS ACPI device is correctly enumerated and
available to the operating system.
BUG=b:382243957
TEST=Able to verify UFS ACPI device is available inside DSDT table.

https://review.coreboot.org/c/coreboot/+/85520/comment/6f02b87d_12f136a8?us… :
PS1, Line 490: .pcie_rp_pcie_speed = 2,
> why we need to set wifi7 as Gen2 ?
As concluded in the 12/7 meeting, based on the current test results for #137, #138, all relevant parties have reached a consensus that the current solution to the issue is to set PCIe root port 4 speed to Gen2, apply the pcie_recovery_patch in #103, and implement the core90_fix in #85 from Intel. Debugging will continue to identify the root cause and develop a comprehensive solution to resolve the issue. Thank you.
