From 81cc32322acb1b3225ee45606ced48e2a14824dc Mon Sep 17 00:00:00 2001 From: TsiChung Liew Date: Thu, 29 May 2008 12:21:54 -0500 Subject: ColdFire: Fix UART baudrate formula The formula "counter = (u32) (gd->bus_clk / gd->baudrate) / 32" can generate the wrong divisor due to integer division truncation. Round the calculated divisor value by adding 1/2 the baudrate before dividing by the baudrate.
