82 Updated to work with latest core. gorban 7995d 21h /
81 Added lastest additions. gorban 7995d 22h /
80 Remove uart_fifo.v because it is replaced by other 2 files. gorban 7995d 22h /
79 Bug Fixes:
* Possible loss of sync and bad reception of stop bit on slow baud rates fixed.
Problem reported by Kenny.Tung.
* Bad (or lack of ) loopback handling fixed. Reported by Cherry Withers.

Improvements:
* Made FIFO's as general inferrable memory where possible.
So on FPGA they should be inferred as RAM (Distributed RAM on Xilinx).
This saves about 1/3 of the Slice count and reduces P&R and synthesis times.

* Added optional baudrate output (baud_o).
This is identical to BAUDOUT* signal on 16550 chip.
It outputs 16xbit_clock_rate - the divided clock.
It's disabled by default. Define UART_HAS_BAUDRATE_OUTPUT to use.
