[PATCH] Staging: Update support for the Universe II VME driver

Martyn Welch martyn.welch at gefanuc.com
Thu Aug 27 16:01:03 UTC 2009


This patch starts the reworking of the vme_ca91cx42.c for the VME core. The
driver seems to have only supported the Universe II for a long time, I have no
hardware to check to see if it would work on the Universe I.

This patch is compile tested with minimal run-time testing. It enables basic
support for slave and master windows and interrupts. The master windows have
undergone basic run testing.
