b993111594 bsp/leon3: Move SMP data to start.S
The LEON3_Boot_Cpu global object is only used by start.S.  Move the definition
of this object to start.S and use a local symbol .Lbootcpuindex for it.

Use a compare-and-swap instruction to assign the boot CPU.  This allows a
concurrent initialization.

Close #4845.

be96cb4345 sparc: Simplify trap table initialization
Move _ISR_Handler() to a separate file since it is now only used if a handler
is installed by _CPU_ISR_install_raw_handler().

Statically initialize the traps for external interrupts to use the new
_SPARC_Interrupt_trap() which directly dispatches the interrupt handlers
installed by rtems_interrupt_handler_install() via the BSP-provided
_SPARC_Interrupt_dispatch().

Since the trap table is now fully statically initialized, there is no longer a
dependency on the Cache Manager in the default configuration.

Update #4458.

d73e657e06 sparc: More reliable bad trap handling
Statically initialize the trap table in start.S to jump to _SPARC_Bad_trap()
for all unexpected traps.  This enables a proper RTEMS fatal error handling
right from the start.  Do not rely on the stack and register settings which
caused an unexpected trap.  Use the ISR stack of the processor to do the fatal
error handling.  Save the full context which caused the trap.  Fatal error
handler may use it for error logging.

Unify the _CPU_Exception_frame_print() implementations and move it to cpukit.

Update #4459.

c344e5828c Use RTEMS_SYSINIT_ORDER_LAST_BUT_5
Use RTEMS_SYSINIT_ORDER_LAST_BUT_5 instead of RTEMS_SYSINIT_ORDER_LAST
to allow applications and support functions to place system
initialization handlers behind the standard handlers.
