2023-02-03efi/cper, cxl: Remove cxl_err.hDan Williams1-1/+11
While going to create include/linux/cxl.h for some cross-subsystem CXL definitions I noticed that include/linux/cxl_err.h was already present. That header has no reason to be global, and it duplicates the RAS Capability Structure definitions in drivers/cxl/cxl.h. A follow-on patch can consider unifying the CXL native error tracing with the CPER error printing. Also fixed up the spec reference as the latest released spec is v3.0.

2022-11-18efi/cper, cxl: Decode CXL Error LogSmita Koralahalli1-0/+27
Print the CXL Error Log field as found in CXL Protocol Error Section. The CXL RAS Capability structure will be reused by OS First Handling and the duplication/appropriate placement will be addressed eventually.

2022-11-18efi/cper, cxl: Decode CXL Protocol Error SectionSmita Koralahalli1-0/+152
Add support for decoding CXL Protocol Error Section as defined in UEFI 2.10 Section N.2.13. Do the section decoding in a new cper_cxl.c file. This new file will be used in the future for more CXL CPERs decode support. Add this to the existing UEFI_CPER config.
