1165 timeout bug fixed; contribution by Carlos markom 7684d 19h /or1k/tags/nog_patch_47/or1ksim/peripheral/16450.c
1153 When multiple interrupts were pending, e.g. TX buffer empty and RX
available, reading the UART's IIR register could potentially clear a
TX interrupt before it had been sent to the processor, thus dropping
the interrupt permanently.

Fix tested w/ both eCos and uclinux.		 sfurman 7742d 14h /or1k/tags/nog_patch_47/or1ksim/peripheral/16450.c
1145 1) Fix trivial bug w/ transmitter empty interrupts that I introduced in the
last check-in.
2) Improve printed output from debugging-only uart_status() routine.		 sfurman 7743d 08h /or1k/tags/nog_patch_47/or1ksim/peripheral/16450.c
1143 Make UART transmitter-empty interrupts match both 16450 and 16550 behavior. sfurman 7746d 05h /or1k/tags/nog_patch_47/or1ksim/peripheral/16450.c
1116 There was a bug in the simulator's UART implementation that caused the
UART's LSR register to become corrupted. This was due to an
assumption that 'char' is an unsigned type, but that is not true on
all platforms.

When the char type is signed and a character is read in the range
0x80-0xff, the high bit is sign-extended into the upper bits of an
entry in the receive FIFO. When the character reaches the head of the
FIFO, the upper bits of the FIFO entry are OR'ed into the LSR, causing
the LSR to be set to 0xFF.

A simple cast fixes the problem.		 sfurman 7786d 12h /or1k/tags/nog_patch_47/or1ksim/peripheral/16450.c
