Author: adrian Date: Thu Aug 19 11:40:10 2010 New Revision: 211502 URL: http://svn.freebsd.org/changeset/base/211502 Log: Add initial Atheros AR91XX support. This works well enough to bring a system up to single-user mode using an MDROOT. Known Issues: * The EHCI USB doesn't currently work and will panic the kernel during attach. * The onboard ethernet won't work until the PLL routines have been fleshed out and shoe-horned into if_arge. * The WMAC device glue (and quite likely the if_ath support) hasn't yet been implemented.
