Module Name: src
Committed By: thorpej
Date: Tue Feb 13 05:35:13 UTC 2024
Modified Files:
src/sys/dev/vme: si.c
Added Files:
src/sys/dev/sun: sireg.h
Removed Files:
src/sys/dev/vme: sireg.h
Log Message:
Move sireg.h from vme/ to sun/ -- the same (or nearly so) register defns
are used by multiple bus attachments.
