Author: adrian Date: Sun Apr 3 14:39:55 2011 New Revision: 220297 URL: http://svn.freebsd.org/changeset/base/220297
Log: Import the initial CPU support for the MIPS RALink RT305x SoC. This is a MIPS4KC CPU with various embedded peripherals, including wireless and ethernet support. This commit includes the platform, UART, ethernet MAC and GPIO support. The interrupt-driven GPIO code is disabled for now pending GPIO changes from the submitter.
