"options OFW_NEWPCI"). This is a bit overdue, the new sparc64 OFW PCI code which is meant to replace the old one is in place for 10 months and enabled by default in GENERIC for 8 months. FreeBSD 5.2 and 5.2.1 also shipped with the new code enabled by default. - Some minor clean-up, e.g. remove functions that encapsulated the #ifdefs for OFW_NEWPCI, remove unused resp. no longer required includes, etc. Approved by: tmm, no objections on freebsd-sparc64
