From fc706437cbb82f8f213b5ebf003ebbfc7a189053 Mon Sep 17 00:00:00 2001 From: Martin Roth Date: Tue, 18 Aug 2015 16:56:05 -0600 Subject: Intel: Move MCRS ResourceTemplate outside of _CRS method On Broadwell, this reduces the number of 'remarks' in the IASL build from 222 to 3. Fixes these remarks: Object is not referenced (Name is within method [_CRS]) The ACPI compiler is trying to be helpful in letting us know that we're not using various fields in the MCRS ResourceTemplate when we define it inside of the _CRS method. Since we're not intending to use those objects in the method, it shouldn't be an issue, but the warning is annoying and can mask real issues. Moving the creation of the MCRS object to outside of the CRS method and referencing it from there solves this problem. This change was made for fsp_baytrail in commit 2eaa0d49 fsp_baytrail: Fix ACPI 'Object is not referenced' warnings Change-Id: I67a1faf963d1868f4133c7747a43a511cd28a44b Signed-off-by: Martin Roth Reviewed-on: http://review.coreboot.org/11268 Tested-by: build bot (Jenkins) Reviewed-by: Paul Menzel Reviewed-by: Alexandru Gagniuc Reviewed-by: Stefan Reinauer --- src/northbridge/intel/sch/acpi/hostbridge.asl | 233 +++++++++++++------------- 1 file changed, 116 insertions(+), 117 deletions(-) (limited to 'src/northbridge/intel/sch') diff --git a/src/northbridge/intel/sch/acpi/hostbridge.asl b/src/northbridge/intel/sch/acpi/hostbridge.asl index cbb17e4845..7670776f40 100644 --- a/src/northbridge/intel/sch/acpi/hostbridge.asl +++ b/src/northbridge/intel/sch/acpi/hostbridge.asl @@ -103,127 +103,126 @@ Device (MCHC) // Current Resource Settings +Name (MCRS, ResourceTemplate() +{ + // Bus Numbers + WordBusNumber (ResourceProducer, MinFixed, MaxFixed, PosDecode, + 0x0000, 0x0000, 0x00ff, 0x0000, 0x0100,,, PB00) + + // IO Region 0 + DWordIO (ResourceProducer, MinFixed, MaxFixed, PosDecode, EntireRange, + 0x0000, 0x0000, 0x0cf7, 0x0000, 0x0cf8,,, PI00) + + // PCI Config Space + Io (Decode16, 0x0cf8, 0x0cf8, 0x0001, 0x0008) + + // IO Region 1 + DWordIO (ResourceProducer, MinFixed, MaxFixed, PosDecode, EntireRange, + 0x0000, 0x0d00, 0xffff, 0x0000, 0xf300,,, PI01) + + // VGA memory (0xa0000-0xbffff) + DWordMemory (ResourceProducer, PosDecode, MinFixed, MaxFixed, + Cacheable, ReadWrite, + 0x00000000, 0x000a0000, 0x000bffff, 0x00000000, + 0x00020000,,, ASEG) + + // OPROM reserved (0xc0000-0xc3fff) + DWordMemory (ResourceProducer, PosDecode, MinFixed, MaxFixed, + Cacheable, ReadWrite, + 0x00000000, 0x000c0000, 0x000c3fff, 0x00000000, + 0x00004000,,, OPR0) + + // OPROM reserved (0xc4000-0xc7fff) + DWordMemory (ResourceProducer, PosDecode, MinFixed, MaxFixed, + Cacheable, ReadWrite, + 0x00000000, 0x000c4000, 0x000c7fff, 0x00000000, + 0x00004000,,, OPR1) + + // OPROM reserved (0xc8000-0xcbfff) + DWordMemory (ResourceProducer, PosDecode, MinFixed, MaxFixed, + Cacheable, ReadWrite, + 0x00000000, 0x000c8000, 0x000cbfff, 0x00000000, + 0x00004000,,, OPR2) + + // OPROM reserved (0xcc000-0xcffff) + DWordMemory (ResourceProducer, PosDecode, MinFixed, MaxFixed, + Cacheable, ReadWrite, + 0x00000000, 0x000cc000, 0x000cffff, 0x00000000, + 0x00004000,,, OPR3) + + // OPROM reserved (0xd0000-0xd3fff) + DWordMemory (ResourceProducer, PosDecode, MinFixed, MaxFixed, + Cacheable, ReadWrite, + 0x00000000, 0x000d0000, 0x000d3fff, 0x00000000, + 0x00004000,,, OPR4) + + // OPROM reserved (0xd4000-0xd7fff) + DWordMemory (ResourceProducer, PosDecode, MinFixed, MaxFixed, + Cacheable, ReadWrite, + 0x00000000, 0x000d4000, 0x000d7fff, 0x00000000, + 0x00004000,,, OPR5) + + // OPROM reserved (0xd8000-0xdbfff) + DWordMemory (ResourceProducer, PosDecode, MinFixed, MaxFixed, + Cacheable, ReadWrite, + 0x00000000, 0x000d8000, 0x000dbfff, 0x00000000, + 0x00004000,,, OPR6) + + // OPROM reserved (0xdc000-0xdffff) + DWordMemory (ResourceProducer, PosDecode, MinFixed, MaxFixed, + Cacheable, ReadWrite, + 0x00000000, 0x000dc000, 0x000dffff, 0x00000000, + 0x00004000,,, OPR7) + + // BIOS Extension (0xe0000-0xe3fff) + DWordMemory (ResourceProducer, PosDecode, MinFixed, MaxFixed, + Cacheable, ReadWrite, + 0x00000000, 0x000e0000, 0x000e3fff, 0x00000000, + 0x00004000,,, ESG0) + + // BIOS Extension (0xe4000-0xe7fff) + DWordMemory (ResourceProducer, PosDecode, MinFixed, MaxFixed, + Cacheable, ReadWrite, + 0x00000000, 0x000e4000, 0x000e7fff, 0x00000000, + 0x00004000,,, ESG1) + + // BIOS Extension (0xe8000-0xebfff) + DWordMemory (ResourceProducer, PosDecode, MinFixed, MaxFixed, + Cacheable, ReadWrite, + 0x00000000, 0x000e8000, 0x000ebfff, 0x00000000, + 0x00004000,,, ESG2) + + // BIOS Extension (0xec000-0xeffff) + DWordMemory (ResourceProducer, PosDecode, MinFixed, MaxFixed, + Cacheable, ReadWrite, + 0x00000000, 0x000ec000, 0x000effff, 0x00000000, + 0x00004000,,, ESG3) + + // System BIOS (0xf0000-0xfffff) + DWordMemory (ResourceProducer, PosDecode, MinFixed, MaxFixed, + Cacheable, ReadWrite, + 0x00000000, 0x000f0000, 0x000fffff, 0x00000000, + 0x00010000,,, FSEG) + + // PCI Memory Region (Top of memory-0xfebfffff) + DWordMemory (ResourceProducer, PosDecode, MinFixed, MaxFixed, + Cacheable, ReadWrite, + 0x00000000, 0x00000000, 0xfebfffff, 0x00000000, + IO_APIC_ADDR,,, PM01) + + // TPM Area (0xfed40000-0xfed44fff) + DWordMemory (ResourceProducer, PosDecode, MinFixed, MaxFixed, + Cacheable, ReadWrite, + 0x00000000, 0xfed40000, 0xfed44fff, 0x00000000, + 0x00005000,,, TPMR) +}) Method (_CRS, 0, Serialized) { -
