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.
