Subject: efi/arm: Show SMBIOS bank/device location in CPER and GHES error logs
X-Git-Tag: v5.2-rc1~208^2~2
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=5e83cfe947444c7f201f8c39ce0189922ec9f578;p=thirdparty%2Fkernel%2Flinux.git

efi/arm: Show SMBIOS bank/device location in CPER and GHES error logs

Run dmi_memdev_walk() for arch arm* as other architectures do.
This improves error logging as the memory device handle is
translated now to the DIMM entry's name provided by the DMI handle.

Before:

 {1}[Hardware Error]:   DIMM location: not present. DMI handle: 0x0038

After:

 {1}[Hardware Error]:   DIMM location: N0 DIMM_A0
