Author: mcayland Date: Wed Aug 11 18:41:36 2010 New Revision: 850 URL: http://tracker.coreboot.org/trac/openbios/changeset/850 Log: Fix up obp_devclose on SPARC32 - Forth's close-dev doesn't actually return a result code, so we fix it as 1 (to indicate success) for the v0 callback as suggested by Google, and simply return nothing for the v2 callback as indicated by the romvec structure. This allows us to remove the extra POP() which was causing a stack underflow error which was affecting Solaris 8 installation kernel boot.

Author: blueswirl Date: Mon Aug 9 21:21:22 2010 New Revision: 846 URL: http://tracker.coreboot.org/trac/openbios/changeset/846 Log: sparc: fix partition probe, try two partitions If the size of the partition currently being probed is zero, fail the probe.
