1165 timeout bug fixed; contribution by Carlos markom 7737d 12h /or1k/tags/nog_patch_42
1161 When OR1200_NO_IMMU and OR1200_NO_IC are not both defined or undefined at the same time, results in a IC bug. Fixed. lampret 7741d 00h /or1k/tags/nog_patch_42
1160 added missing .rodata.* section into rom linker script phoenix 7772d 01h /or1k/tags/nog_patch_42
1159 No functional changes. Added defines to disable implementation of multiplier/MAC lampret 7784d 03h /or1k/tags/nog_patch_42
1158 Added simple uart test case. lampret 7785d 04h /or1k/tags/nog_patch_42
1157 Added syscall test case. lampret 7785d 05h /or1k/tags/nog_patch_42
1156 Tick timer test case added. lampret 7786d 01h /or1k/tags/nog_patch_42
1155 No functional change. Only added customization for exception vectors. lampret 7787d 05h /or1k/tags/nog_patch_42
1154 When using tty channel, put the serial port into raw mode (no echo, no
CR/LF conversion, no other line discipline/buffering).		 sfurman 7794d 20h /or1k/tags/nog_patch_42
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 7795d 07h /or1k/tags/nog_patch_42

1146 cygwin fix phoenix 7796d 00h /or1k/tags/nog_patch_42
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 7796d 01h /or1k/tags/nog_patch_42
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 7798d 07h /or1k/tags/nog_patch_42
1143 Make UART transmitter-empty interrupts match both 16450 and 16550 behavior. sfurman 7798d 21h /or1k/tags/nog_patch_42
