New Revision: 196431
URL: http://svn.freebsd.org/changeset/base/196431
Log:
- MFC r196246:
- 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.
