From f624b6f39a8d47a2bc83144a6f3d3da8d221dce8 Mon Sep 17 00:00:00 2001 From: ian Date: Wed, 14 May 2014 01:53:20 +0000 Subject: [PATCH] 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. git-svn-id: svn://svn.freebsd.org/base/stable/10@266000 ccf9f872-aa2e-dd11-9fc8-001c23d0bc1f --- sys/arm/arm/nexus.c | 91 ++++++---- sys/arm/broadcom/bcm2835/bcm2835_fb.c | 2 +- sys/arm/freescale/imx/tzic.c | 4 +- sys/arm/mv/mv_localbus.c | 2 +- sys/arm/mv/mv_pci.c | 2 +- sys/conf/files | 2 +- sys/dev/fdt/simplebus.c | 2 +- sys/dev/mii/atphy.c | 1 + sys/dev/mii/miidevs | 1 + sys/dev/ofw/ofw_fdt.c | 95 +++------- sys/mips/mips/nexus.c | 246 ++++++++++++++------------ sys/powerpc/booke/pmap.c | 2 +- sys/powerpc/mpc85xx/lbc.c | 2 +- sys/powerpc/mpc85xx/pci_mpc85xx.c | 2 +- 14 files changed, 233 insertions(+), 221 deletions(-) diff --git a/sys/arm/arm/nexus.c b/sys/arm/arm/nexus.c index 9b5047ecd..a5f9022e8 100644 --- a/sys/arm/arm/nexus.c +++ b/sys/arm/arm/nexus.c @@ -60,6 +60,12 @@ __FBSDID("$FreeBSD$");
