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/ec/google/chromeec/acpi/ec.asl | 1 - src/ec/google/chromeec/acpi/emem.asl | 1 - 2 files changed, 2 deletions(-) (limited to 'src/ec/google/chromeec') diff --git a/src/ec/google/chromeec/acpi/ec.asl b/src/ec/google/chromeec/acpi/ec.asl index ce2455f30b..218d08b091 100644 --- a/src/ec/google/chromeec/acpi/ec.asl +++ b/src/ec/google/chromeec/acpi/ec.asl @@ -31,7 +31,6 @@ Device (EC0) OperationRegion (ERAM, EmbeddedControl, 0x00, EC_ACPI_MEM_MAPPED_BEGIN) Field (ERAM, ByteAcc, Lock, Preserve) { - Offset (0x00), RAMV, 8, // EC RAM Version TSTB, 8, // Test Byte TSTC, 8, // Complement of Test Byte diff --git a/src/ec/google/chromeec/acpi/emem.asl b/src/ec/google/chromeec/acpi/emem.asl index 77a6f71139..2a556edc68 100644 --- a/src/ec/google/chromeec/acpi/emem.asl +++ b/src/ec/google/chromeec/acpi/emem.asl @@ -4,7 +4,6 @@ * EMEM data may be accessed through port 62/66 or through LPC at 900h. */ -Offset (0x00), TIN0, 8, // Temperature 0 TIN1, 8, // Temperature 1 TIN2, 8, // Temperature 2 -- cgit v1.2.3
