When OR1200_NO_IMMU and OR1200_NO_IC are not both defined or undefined at the same time, results in a IC bug. Fixed. |

When using tty channel, put the serial port into raw mode (no echo, no
CR/LF conversion, no other line discipline/buffering). |

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. |

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. |

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. |
