[U-Boot] [PATCH 5/7 v7] serial: add S3C64XX serial driver

[Harald Welte]

Hi Guennadi,

thanks for all your s3c64xx work.  It's great to see that later s3c SoCs
receive better u-boot integration from the start.

I would prefer to see multi-serial (CONFIG_SERIAL_MULTI) support in this,
but it's definitely something that can be added later.

Also, CONFIG_HWFLOW is probably not working (I guess you need to set UMCON bit
0x1, just like in the s3c24xx serial driver in cpu/arm920t/s3c24xx/serial.c in
order to activate nRTS.  I checked the s3c6400 documentation and it seems to be identical with s3c24xx)

As you will also see, the s3c24xx UART is very similar to the s3c64xx UART.
I'm not sure if it is worth sharing the code, though, since it's only a couple
of lines...
