  • configure.in: Added new directories.
  • shared/interrupts/Makefile.am: Added AM_CPPFLAGS to define TX39 when compiling for a TX3904.
  • shared/interrupts/maxvectors.c: Corrected conditional logic.
  • tx39/Makefile.am: Added vectorisrs.
  • tx39/vectorisrs/Makefile.am, tx39/vectorisrs/vectorisrs.c,
  • tx39/vectorisrs/.cvsignore: New files. This decodes the interrupt pending information on the TX3904 and vectors an interrupt.
  • Property mode set to 100644

17 *  The tx3904 attaches 4 of the eight interrupt bits to an on-CPU interrupt
18 *  controller so that these four bits map to 16 unique interrupts.
19 *  So you have: 2 software interrupts, an NMI, and 16 others.
