96baa4c376 serial: pl01x: drain PL01x FIFO before baudrate change
Not draining the FIFO and waiting for the UART to be non-busy
before changing baudrate results in crap characters on the
console, so let's wait for the FIFO to drain and the last
character to be clocked out before we do that.

910f1ae3eb Serial: p1011: new vendor init options
Two new options:

CONFIG_PL011_SERIAL_RLCR

Some vendor versions of PL011 serial ports (e.g. ST-Ericsson U8500)
have separate receive and transmit line control registers.  Set
this variable to initialize the extra register.

CONFIG_PL011_SERIAL_FLUSH_ON_INIT

On some platforms (e.g. U8500) U-Boot is loaded by a second stage
boot loader that has already initialized the UART.  Define this
variable to flush the UART at init time.

72d5e44c95 pl01x: use C structs and readl/writel
Use C structs for registers, and use readl/writel instead of custom
accessors.

249d5219c4 ARMV7: Fixed baudrate setting in pl01x driver
The pl01x serial driver was lacking the code to switch baudrates from the
command line.  Fixed by simply saving the new baudrate and calling
serial_init() again.  Also fixed CamelCase variables, I/O accessors and
comment style.

20c9226cb8 Merged serial_pl010.c and serial_pl011.c.
They only differ in the init function.
This also adds the missing watchdog support for the PL011.
