Module Name: src
Committed By: matt
Date: Sun Jul 10 06:26:02 UTC 2011
Modified Files:
src/sys/arch/mips/atheros: ar9344.c ar_conf.c ar_console.c arbus.c
src/sys/arch/mips/atheros/include: arbusvar.h platform.h
Added Files:
src/sys/arch/mips/atheros: arbusle.c
src/sys/arch/mips/atheros/dev: ehci_arbus.c
Log Message:
Add athers_get_uart_freq() (since AR7240 uses the ref_clk, not the bus_clk).
Add little endian bus_space_tag for arbus.
Add EHCI attachment for arbus.
