[U-Boot-Users] [PATCH] ColdFire: Fix UART baudrate formula
From: TsiChung Liew [EMAIL PROTECTED] 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.
