[U-Boot] [PATCH] at91: Factored out common serial hardware initialization
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.

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.

Can't find it.
Neither can I.
Jean-Christophe - it would be really helpful if you could include at least subject and posting date, or even better a URL for the postingin one of the mailing list archives, instead of just stating "I've send similar patch". Please keep this in mind for the future.
Thanks.
Best regards,
Wolfgang Denk

Similar, but Michel's patch looks better to me. Fr example, he get's rid of all the many #ifdef CONFIG_USARTx which you still keep for no good reason.
My vote is: please apply Michael's patch.
