* include/bsp.h, startup/bspstart.c: confdefs.h now wants
us to use BSP_INTERRUPT_STACK_SIZE instead of
CONFIGURE_INTERRUPT_STACK_MEMORY. Removed reference to
CONFIGURE_INTERRUPT_STACK_MEMORY from bspstart.c
* shared/startup/pretaskinghook.c: install pointer
to rtems_malloc_sbrk_helpers_table. This (and derived)
BSPs rely on sbrk delivering even the first/initial
chunk of memory.
* new-exceptions/bspsupport/irq.c: don't disable irqs
at the interrupt controller (PIC) during initialization -- this
caused problems where some BSPs's BSP_disable_irq_at_pic() routine
did not ignore IRQ lines associated with cascaded PICs.
Rely on the BSP (BSP_setup_the_pic()) to provide a good
initial setup.
* shared/startup/pretaskinghook.c: install pointer
to rtems_malloc_sbrk_helpers_table. This (and derived)
BSPs rely on sbrk delivering even the first/initial
chunk of memory.
* 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.
