* README: Updated. We are now vectoring a clock tick ISR handler.
But RTEMS is not returning from the ISR properly.
* clock/clockdrv.c: Now causes interrupts but has not been calibrated.
* include/bsp.h: Use <libcpu/tx3904.h>
* startup/Makefile.am: Add setvec.c from shared.
* startup/bspstart.c: Initialize the status register (SR) so
no interrupts are masked but global interrupts (SR_IEC) are off.
Added call to install the ISR prologue code.
* wrapup/Makefile.am: Pick up more pieces from libcpu.
