- enhancement: provide routines to take and print stack trace
snapshots
- add definitions for HID1 and DABR SPRs

* shared/include/io.h: Per PR215 address the following issues:
- _IO_BASE, _ISA_MEM_BASE and PCI_DRAM_OFFSET
are no longer defined by libcpu (powerpc/shared/include/io.h)
but by the BSP (who is the only one to know the values)
- the affected BSP (shared/motorola) headers have been fixed
in a separate "libbsp/powerpc/shared" patch.
- the DEC 21140 driver (libchip/network/dec21140.c) has been
fixed to use PCI_DRAM_OFFSET instead of PREP_PCI_DRAM_OFFSET.
and PCI_MEM_BASE instead of PREP_ISA_MEM_BASE. PCI_MEM_BASE
is to be defined by the BSP who is using this driver.
- the DEC driver also has been fixed to use the newer
rtems_bsp_delay_in_bus_cycles() instead of the obsolete
delay_in_bus_cycles().
* rtems/powerpc/registers.h, rtems/score/ppc.h: Per PR213, add
the following:
- support for the MPC74000 (AKA G4); there is no
AltiVec support yet, however.
- the cache flushing assembly code uses hardware-flush on the G4.
Also, a couple of hardcoded numerical values were replaced
by more readable symbolic constants.
- extended interrupt-disabled code section so enclose the entire
cache flush/invalidate procedure (as recommended by the book).
This is not (latency) critical as it is only used by
init code but prevents possible corruption.
- Trivial page table support as been added.
(1:1 effective-virtual-physical address mapping which is only
useful only on CPUs which feature hardware TLB replacement,
e.g. >604. This allows for write-protecting memory regions,
e.g. text/ro-data which makes catching corruptors a lot easier.
It also frees one DBAT/IBAT and gives more flexibility
for setting up address maps :-)
- setdbat() allows changing BAT0 also (since the BSP may use
a page table, BAT0 could be available...).
- asm_setdbatX() violated the SVR ABI by using
r20 as a scratch register; changed for r0
- according to the book, a context synchronizing instruction is
necessary prior to and after changing a DBAT -> isync added
