It seems to me that the below chunk of comment needs to be updated for the
rename to the 'BaseListMarkerPointer' as well:
//
// Fill in EFI_DEBUG_INFO
//
// Here we skip the first 4 bytes of Buffer, because we must ensure
BaseListMarker is
// 64-bit aligned, otherwise retrieving 64-bit parameter from BaseListMarker
will cause
// exception on IPF. Buffer starts at 64-bit aligned address, so skipping 4
types (sizeof(EFI_DEBUG_INFO))
// just makes address of BaseListMarker, which follows DebugInfo, 64-bit
aligned.
//
There is no need to re-send the patch again if there is no other major
change in the patch series. And you can keep my previous 'Reviewed-by'
tag given in V3 of the series.
