* vmeUniverse/vmeTsi148.c: Initialize VME Master
'VTON' timer and bus-release policy to less aggressive
values than the chip's defaults. The default VTON easily
overrides any settings used by the DMA engine.
* new-exceptions/bspsupport/ppc_exc_asm_macros.h,
new-exceptions/bspsupport/ppc_exc.S,
new-exceptions/bspsupport/README,
new-exceptions/bspsupport/ppc_exc_hdl.c:
Thomas Doerfler clarified (thanks!) that raising an
exception and executing the 1st instruction is not
an atomical operation. I added a fix to the code that
checks if a lower-priority interrupt is under way:
we now not only test if the 'lock' variable was set
but also check if the interrupted PC points to the
'write lock' instruction.
Added more comments and updated README.
* sapi/include/confdefs.h: Do not reserve 2 * minimum stack size
for the ITRON initialization tasks ALL the time.
Do not reserve memory for the object name table since it does not
exist any longer.
* sapi/include/rtems/sptables.h: Fix typo.
* rtems.adb, rtems.ads: Refactored rtems_clock_get into 5 methods
which are single purpose and more strongly typed. They are:
rtems_clock_get_tod - Get TOD in Classic API structure
rtems_clock_get_tod_timeval - Get TOD in struct timeval
rtems_clock_get_seconds_since_epoch - Get TOD as seconds since 1988
rtems_clock_get_ticks_since_boot - Get ticks since boot
rtems_clock_get_ticks_per_second - Get ticks per second
Also switch from using 'Unchecked_Access to 'Access.
Added pragma Convention C as required by gcc > 4.3.
Changed style of parenthese on subprogram calls to match GNAT.
* user/clock.t: Refactored rtems_clock_get into 5 methods which
are single purpose and more strongly typed. They are:
rtems_clock_get_tod - Get TOD in Classic API structure
rtems_clock_get_tod_timeval - Get TOD in struct timeval
rtems_clock_get_seconds_since_epoch - Get TOD as seconds since 1988
rtems_clock_get_ticks_since_boot - Get ticks since boot
rtems_clock_get_ticks_per_second - Get ticks per second
* rtems/Makefile.am, rtems/include/rtems/rtems/clock.h,
rtems/src/clockget.c:
* rtems/src/clockgetsecondssinceepoch.c,
rtems/src/clockgettickspersecond.c,
rtems/src/clockgettickssinceboot.c, rtems/src/clockgettod.c,
rtems/src/clockgettodtimeval.c: New files.

* libmisc/shell/main_cp.c, libmisc/shell/main_netstats.c,
libmisc/shell/shell_script.c: Add memset() of getopt_data to
ensure it is zeroed out each time we use getopt_r().
* libmisc/shell/shell.c: Do not echo commands if input is not a tty.
This makes the scripts behave more like UNIX scripts.
* start/start.S, startup/bspstart.c: disable memory-select
errors early (in start.S) to avoid hangs due to speculative
memory access (motload maps absent memory in TLBs).
Remove TLB mappings for which no physical memory is installed
(bspstart). Enable HID1[RFXE] so that 'core_fault_in' errors
result in a machine-check rather than stalling the machine.
Re-enable memory-select errors at this point.
