From 6e2c2e42f00b0432adf7a545a09f9aa81d19e7d0 Mon Sep 17 00:00:00 2001 From: stas Date: Sat, 15 Aug 2009 15:15:20 +0000 Subject: - 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.
