From 48a6c018bcb8a182c4934d2788567e512d490f96 Mon Sep 17 00:00:00 2001 From: Elyes HAOUAS Date: Wed, 8 Jul 2020 09:22:13 +0200 Subject: src: Remove redundant use of ACPI offset(0) IASL version 20180927 and greater, detects Unnecessary/redundant uses of the Offset() operator within a Field Unit list. It then sends a remark "^ Unnecessary/redundant use of Offset" example: OperationRegion (OPR1, SystemMemory, 0x100, 0x100) Field (OPR1) { Offset (0), // Never needed FLD1, 32, Offset (4), // Redundant, offset is already 4 (bytes) FLD2, 8, Offset (64), // OK use of Offset. FLD3, 16, } We will have those remarks: dsdt.asl 14: Offset (0), Remark 2158 - ^ Unnecessary/redundant use of Offset operator dsdt.asl 16: Offset (4), Remark 2158 - ^ Unnecessary/redundant use of Offset operator Change-Id: I260a79ef77025b4befbccc21f5999f89d90c1154 Signed-off-by: Elyes HAOUAS Reviewed-on: https://review.coreboot.org/c/coreboot/+/43283 Reviewed-by: Felix Held Reviewed-by: Marshall Dawson Reviewed-by: Jason Glenesk Tested-by: build bot (Jenkins) --- src/soc/intel/cannonlake/acpi/scs.asl | 3 +-- 1 file changed, 1 insertion(+), 2 deletions(-) (limited to 'src/soc/intel/cannonlake/acpi') diff --git a/src/soc/intel/cannonlake/acpi/scs.asl b/src/soc/intel/cannonlake/acpi/scs.asl index 8e1de1e0e1..462e65a086 100644 --- a/src/soc/intel/cannonlake/acpi/scs.asl +++ b/src/soc/intel/cannonlake/acpi/scs.asl @@ -23,8 +23,7 @@ Scope (\_SB.PCI0) { OperationRegion(SCSR, PCI_Config, 0x00, 0x100) Field(SCSR, WordAcc, NoLock, Preserve) { - Offset (0x0), /* PCI VID DID */ - VDID, 32, + VDID, 32, /* PCI VID DID */ Offset (0x84), /* PMECTRLSTATUS */ PMCR, 16, Offset (0xA2), /* PG_CONFIG */ -- cgit v1.2.3
