Subject: - disabled FT2232 debug output (that code should be fairly stable) -
 fixed bug in jtag.c where JTAG command type was wrong for PATHMOVE commands -
 added lattice ISP cable (experimental) - properly initialize parallel port
 (clear tristate bit) - fixed jtag/Makefile.am that failed with some versions
 of autotools - print error number if read() in gdbserver.c failed on Windows
 - fixed handling of opcodes with bits 27-25 b011 (comment was correct, code
 had a bug) - added support for AT91SAM7SE internal flash
