PMC controller gets hidden during FSP Silicon initialization using sideband interface on CNP-PCH. Hence unable to reserve PMC IO resources during PCI enumeration process. This causes hang issue on non-chrome platform with CNP-PCH due to ABASE corruption. This patch ensures PMC IO resource (ABASE) is getting reserved (IO address 0x1800-0x1900) and ACPI base is not overwritten by other devices. TEST=ABASE range is reserved along with LPC IO range during PCI enumeration. PCI: 00:1f.0 resource base 1800 size 100 align 0 gran 0 limit 0 flags c0000100 index 20 Change-Id: I1fbc4339ae11058fb3daedf4ffedda1904fa52ec Signed-off-by: Subrata Banik <subrata.banik@intel.com> Reviewed-on: https://review.coreboot.org/23202 Tested-by: build bot (Jenkins) <no-reply@coreboot.org> Reviewed-by: Aaron Durbin <adurbin@chromium.org> |
