Author: nwhitehorn Date: Tue Nov 5 13:48:34 2013 New Revision: 257702 URL: http://svnweb.freebsd.org/changeset/base/257702 Log: Teach nexus(4) about Open Firmware (e.g. FDT) on ARM and MIPS, retiring fdtbus in most cases. This brings ARM and MIPS more in line with existing Open Firmware platforms like sparc64 and powerpc, as well as preventing double-enumeration of the OF tree on embedded PowerPC (first through nexus, then through fdtbus). This change is also designed to simplify resource management on FDT platforms by letting there exist a platform-defined root bus resource_activate() call instead of replying on fdtbus to do the right thing through fdt_bs_tag. The OFW_BUS_MAP_INTR() and OFW_BUS_CONFIG_INTR() kobj methods are also available to implement for similar purposes. Discussed on: -arm, -mips Tested by: zbb, brooks, imp, and others MFC after: 6 weeks Modified: head/sys/arm/arm/nexus.c head/sys/arm/broadcom/bcm2835/bcm2835_fb.c head/sys/arm/freescale/imx/tzic.c head/sys/arm/mv/mv_localbus.c head/sys/arm/mv/mv_pci.c head/sys/conf/files head/sys/dev/fdt/simplebus.c head/sys/mips/mips/nexus.c head/sys/powerpc/mpc85xx/lbc.c head/sys/powerpc/mpc85xx/pci_mpc85xx.c Modified: head/sys/arm/arm/nexus.c ============================================================================== --- head/sys/arm/arm/nexus.c Tue Nov 5 13:36:05 2013 (r257701) +++ head/sys/arm/arm/nexus.c Tue Nov 5 13:48:34 2013 (r257702) @@ -60,6 +60,12 @@ __FBSDID("$FreeBSD$");
