[OpenBIOS] r147 - in openbios-devel: arch/sparc32 drivers

Author: blueswirl
Date: 2007-05-17 21:16:06 +0200 (Thu, 17 May 2007)
New Revision: 147

Modified:
   openbios-devel/arch/sparc32/tree.fs
   openbios-devel/drivers/esp.c
   openbios-devel/drivers/obio.c
   openbios-devel/drivers/sbus.c
Log:
NetBSD and OpenBSD fixes:
 - Correct timer and interrupt controller mappings
 - Add ESP clock frequency to avoid division by zero
 - CS4231 exists only in SS5
 - Disable BPP for now, it's not emulated by Qemu anyway
With these fixes, one NetBSD kernel even got to root device prompt on SS5.
