ebd2c8f6d2 serial: kill off uart_info
We moved this into uart_state, now move the fields out of the separate
structure and kill it off.

dcb314@hotmail.com notes that this memset has its args reversed.

It's unneeded anyway, so remove it.

4328e3e5ef Blackfin SPORT UART: rewrite inline assembly
Hopefuly the new version is easier to read, but in the process it declares
proper clobber lists and better constraints so that GCC can do a better
job at allocating free registers.

a19e8b2059 Blackfin SPORT UART: fix data misses while using transmit frame sync
SPORT transmit frame sync (TFS) isn't used as an electrical signal during
normal SPORT UART emulation.  However, it is useful in EIA RS-485
emulation as RS-485 Transceiver Driver Enable DE strobe.

This patch configures:
TFS to be active high in order to drive an DE strobe of
an eventually connected RS-485 Transceiver.

Late frame sync mode (LATFS) gating the entire TX shift cycle.
