This isolates the ptrace code for the special-case registers msr and trap
from the ptrace-layout dispatch code. This should inline away completely.
It cleanly separates the low-level machine magic that has to be done for
deep reasons, from the superficial details of the ptrace interface.
This switches powerpc to using the user_regset-based code for ELF core
dumps. The core dumps come out exactly the same either way, except that
the NT_PPC_VMX note is now omitted for any thread that never touched its
Altivec registers (thread_struct.vr_used).

This makes the SPE register data appear in ELF core dumps,
using the new n_type value NT_PPC_SPE (0x101). This new

1) Add basic support for Wind River SBC8560 as powerpc
This adds in the basic platform support file -- closely matching that which

Such accesses are thus inherently racy, vs. interrupts, preemption
and possibly SMP if 4xx SMP cores are ever used.
This updates the mfdcri/mtdcri macros in dcr-native.h (which were

This version implement the basic support for the 405GP bridge,
I haven't yet looked at differences that other implementations
may have for the PCI 2.x part.
This adds to the previous 2 patches the support for the 4xx PCI Express
cells as found in the 440SPe revA, revB and 405EX.
Unfortunately, due to significant differences between these, and other
interesting features of those pieces of HW, the code isn't as simple
as it is for PCI and PCI-X and

This adds the definition of the on-chip OHCI controller to the
Bamboo board's device-tree. This is enough to get it probed and
working, though a separate patch fixing a bug in the OHCI driver
is needed to make it reliable.

This reworks the boot wrapper library function that probes
the chip clocks. Better separate the base function that is
used on 440GX,SPe,EP,... from the uart fixups as those need
different device-tree path on different processors.
Also, rework the function itself based on the arch/ppc code

This removes a bogus empty ranges property in the EBC device node
of the Bamboo board device-tree.
The ranges property will be created by the boot wrapper, there is
no need to have an empty property there, and that causes recent

This improves the way the 4xx PCI-E code handles checking for a link
and adds explicit testing of CRS result codes on config space accesses.
This should make it more reliable.
Also, bridges with no link are now still created, though config space
accesses beyond the root complex are filtered.
