1143 Make UART transmitter-empty interrupts match both 16450 and 16550 behavior. sfurman 7770d 06h /or1k/tags/stable_0_2_0_rc3/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 7810d 14h /or1k/tags/stable_0_2_0_rc3/or1ksim/peripheral/16450.c
1073 channels support rprescott 7935d 18h /or1k/tags/stable_0_2_0_rc3/or1ksim/peripheral/16450.c
997 PRINTF should be used instead of printf; command redirection repaired markom 7999d 04h /or1k/tags/stable_0_2_0_rc3/or1ksim/peripheral/16450.c
970 Testbench is now running on ORP architecture platform. simons 8006d 15h /or1k/tags/stable_0_2_0_rc3/or1ksim/peripheral/16450.c
884 code cleaning - a lot of global variables moved to runtime struct markom 8043d 02h /or1k/tags/stable_0_2_0_rc3/or1ksim/peripheral/16450.c
821 ugly bug with duplicate redefined i removed markom 8128d 23h /or1k/tags/stable_0_2_0_rc3/or1ksim/peripheral/16450.c
806 uart now partially uses scheduler markom 8134d 05h /or1k/tags/stable_0_2_0_rc3/or1ksim/peripheral/16450.c
805 kbd, fb, vga devices now uses scheduler markom 8134d 05h /or1k/tags/stable_0_2_0_rc3/or1ksim/peripheral/16450.c
713 lot of small minor improvements: code documented, cleaned; runs at about same speed when not actually logging, but exe_log is enabled; raw_stats now run only with simple execution - enable RAW_USAGE_STATS macro markom 8171d 03h /or1k/tags/stable_0_2_0_rc3/or1ksim/peripheral/16450.c
