[U-Boot] [PATCH 2/5] serial: pl01x: fix pl011 baud rate configuration

2014-11-17 Thread Vikas Manocha
UART_IBRD, UART_FBRD, and UART_LCR_H form a single 30-bit wide register which is updated on a single write strobe generated by a UART_LCR_H write. So, to internally update the content of UART_IBRD or UART_FBRD, a write to UART_LCR_H must always be performed at the end. Signed-off-by: Vikas Manocha
