1157 Added syscall test case. lampret 7710d 13h /or1k/tags/rel_12/
1156 Tick timer test case added. lampret 7711d 09h /or1k/tags/rel_12/
1155 No functional change. Only added customization for exception vectors. lampret 7712d 13h /or1k/tags/rel_12/
1154 When using tty channel, put the serial port into raw mode (no echo, no
CR/LF conversion, no other line discipline/buffering).		 sfurman 7720d 04h /or1k/tags/rel_12/
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 7720d 15h /or1k/tags/rel_12/

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 7721d 09h /or1k/tags/rel_12/
1144 Speed up gdb when running with serial targets:

When generating backtraces, the prologue of each function is scanned
at least three times by architecture-independent code, e.g. to
determine offsets of saved registers, identify frameless functions,
etc. This new code adds straightforward caching of the information
gleaned by or1k_scan_prologue() on a per-frame basis rather than
storing it in global static variables. (This benefits both JTAG and
serial gdb targets, though the JTAG target runs fast enough that it is
not particularly needed.)

When the register set is dumped by the serial target, e.g. at any
breakpoint or interrupt, the 32 vector/FP registers were included in
the dump (each 8 bytes long), though they aren't implemented. The new
code tells gdb that unimplemented registers have zero length in the
dump.		 sfurman 7723d 15h /or1k/tags/rel_12/
1143 Make UART transmitter-empty interrupts match both 16450 and 16550 behavior. sfurman 7724d 05h /or1k/tags/rel_12/
