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 <ehaouas@noos.fr> Reviewed-on: https://review.coreboot.org/c/coreboot/+/43283 Reviewed-by: Felix Held <felix-coreboot@felixheld.de> Reviewed-by: Marshall Dawson <marshalldawson3rd@gmail.com> Reviewed-by: Jason Glenesk <jason.glenesk@gmail.com> Tested-by: build bot (Jenkins) <no-reply@coreboot.org>
