* configure.ac, irq/irq.c, startup/bspclean.c, startup/bspstart.c: Add
ALLOW_IRQ_NESTING option. The MPC5200 has a settle time after
acknowledging the IRQs and currently the BSP does not account for
that. After acknowledging an interrupt, it currently gets a second
spurious IRQ a significant percentage of the time. Rename to
BENCHMARK_IRQ_PROCESSING and get it working again. Under one test
load, not nesting interrupts resulted in a 50% reduction in the
number of IRQs and an ~30% reduction in time spent in IRQs.
* bsp_specs: added crtend.o back to the endfiles. Otherwise,
C++ static constructors are not executed because the
call to __do_global_ctors_aux() is emitted into the .init
section by this endfile (yes, the endfile contributes to .init).
* gdb-init: Make the first hb temporary.
* network/network.c: Add support for reading the MAC address from
the FEC if set by the boot monitor. dBug does not do this unless
the network is used which is a shame.
* Makefile.am, irq/irq.c (removed), irq/irq_init.c:
Use shared exception/interrupt support from
libcpu/new-exceptions/bspsupport. NOTE: CHANGES MUST BE
TESTED ON REAL HARDWARE.
* Makefile.am, irq/irq.c, irq/irq.h, irq/irq_init.c:
use new exception/irq support from
libcpu/powerpc/new-exceptions/bspsupport
rather than borrowing from ../shared/vectors ../shared/irq
* Makefile.am, new-exceptions/bspsupport/README:
provide new irq_bspsupport.rel which was
split out of exc_bspsupport.rel to provide finer-grained
control over what BSPs want to use.
* include/bsp.h, startup/bspstart.c: Eliminate copies of the
Configuration Table. Use the RTEMS provided accessor macros to obtain
configuration fields.
* clock/clockdrv.c, include/bsp.h, startup/bspstart.c: Eliminate copies
of the Configuration Table. Use the RTEMS provided accessor macros to
obtain configuration fields.
* clock/clock.c, include/bsp.h, startup/bspstart.c: Eliminate copies of
the Configuration Table. Use the RTEMS provided accessor macros to
obtain configuration fields.
* clock/ckinit.c, include/bsp.h, startup/bspstart.c: Eliminate copies
of the Configuration Table. Use the RTEMS provided accessor macros to
obtain configuration fields.
* README, clock/ckinit.c, include/bsp.h, startup/bspstart.c: Eliminate
copies of the Configuration Table. Use the RTEMS provided accessor
macros to obtain configuration fields.
* shared/startup/bspstart.c, shared/startup/pretaskinghook.c: Eliminate
copies of the Configuration Table. Use the RTEMS provided accessor
macros to obtain configuration fields.
* README, include/bsp.h, startup/bspstart.c: Eliminate copies of the
