+ Support for the BCM2835 auxiliar mini UART.
+
+ Features and limitations of the UART are
+ Registers are similar to 16650 registers,
+ set bits in the control registers that are unsupported
+ are ignored and read back as 0
+ 7/8 bit operation with 1 start and 1 stop bit
+ 8 symbols deep fifo for rx and tx
+ SW controlled RTS and SW readable CTS
+ Clock rate derived from system clock
+ Uses 8 times oversampling (compared to 16 times for 16650)
+ Missing break detection (but break generation)
+ Missing framing error detection
+ Missing parity bit
+ Missing receive time-out interrupt
+ Missing DCD, DSR, DTR and RI signals
+
+ If unsure, say N.
