Author: stas Date: Sat Aug 15 15:15:20 2009 New Revision: 196246 URL: http://svn.freebsd.org/changeset/base/196246 Log: - Proprely intialize UART parameters at probe stage, so uart(4) will initialize the FIFO memory correctly on attach. Before that this values was intialized in only in at91_usart_bus_attach which is called after the uart(4) memory allocation happens.
