CVS commit: src/sys/arch/virt68k/virt68k

Module Name:	src
Committed By:	thorpej
Date:		Tue Mar 31 13:45:00 UTC 2026

Modified Files:
	src/sys/arch/virt68k/virt68k: bus_dma.c

Log Message:
Fill in bus_dmamap_sync() for 68030.  Since 68030 caches are write-through,
this is pretty trivial: just invalidate the on-chip + any external D cache
in the PREREAD case.  (See comment in code for why PREREAD is preferred
over POSTREAD.)
