Author: imp Date: Mon Jan 25 19:27:20 2010 New Revision: 202985 URL: http://svn.freebsd.org/changeset/base/202985 Log: Export knowledge of the special bus space we use for the console to obio. Take advantage of the fact that obio only really supports uart at the moment to use the uart bus tag always for IOPORT allocations. # this needs to be redone to conform to FreeBSD standards and allow for # additional drivers for SoC hardware to attach Modified: head/sys/mips/cavium/obio.c head/sys/mips/cavium/uart_cpu_octeonusart.c Modified: head/sys/mips/cavium/obio.c ============================================================================== --- head/sys/mips/cavium/obio.c Mon Jan 25 19:25:21 2010 (r202984) +++ head/sys/mips/cavium/obio.c Mon Jan 25 19:27:20 2010 (r202985) @@ -36,8 +36,8 @@ */ /* - * On-board device autoconfiguration support for Intel IQ80321 - * evaluation boards. + * On-board device autoconfiguration support for Cavium OCTEON 1 family of + * SoC devices. */ #include <sys/cdefs.h> @@ -56,6 +56,8 @@ __FBSDID("$FreeBSD$"); #include <mips/cavium/octeon_pcmap_regs.h> #include <mips/cavium/obiovar.h> +extern struct bus_space octeon_uart_tag; + int obio_probe(device_t); int obio_attach(device_t); @@ -125,7 +127,7 @@ obio_alloc_resource(device_t bus, device return (NULL); case SYS_RES_IOPORT: rm = &sc->oba_rman; - bt = sc->oba_st; + bt = &octeon_uart_tag; bh = device_get_unit(child) ?
