Author: ian Date: Wed May 14 01:53:20 2014 New Revision: 266000 URL: http://svnweb.freebsd.org/changeset/base/266000 Log: MFC r257702, r257745, r257746, r257747, r257751, r257791, r257793, r257794, r257795, r257992 Teach nexus(4) about Open Firmware (e.g. FDT) on ARM and MIPS, retiring fdtbus in most cases. Make OF_nextprop() work correctly for FDT by using the libfdt fdt_next_property_offset() API. Do not panic if pmap_mincore() is called. An addendum: it is possible, though of questionable utility, for a node to have no properties at all. Add definition for the Atheros 8021 gigabit PHY. Consolidate Apple firmware hacks and improve them by switching on the presence of mac-io devices in the tree, which uniquely identifies Apple hardware. Allow OF_decode_addr() to also be able to map resources on big-endian devices. Make tsec work with the device tree present on the RB800. Be more flexible about which compatible strings to accept. This brings up the PCI Express bus on the RB800 using the firmware device tree. Rename the "bare" platform "mpc85xx", which is what it actually is, and add actual platform probing based on PVR.
