[U-Boot] [PATCH] at91: Factored out common serial hardware initialization
Michael Roth
mroth at nessie.de
Thu Feb 5 14:01:07 CET 2009
Created a new function at91_serial_hw_init() which sets up the
dedicated PIO pins of several at91 SoC according to CONFIG_USARTx.
Please note that the used pins for serial communication varies on
different at91 SoC independently of the logic functionality equality
of the serial hardware.
