Scott Wood 9dd5eba1bc PPC: e500: increase DTC_LOAD_PAD
An allowance of 5 MiB for BSS is not enough for Linux kernels with certain
debug options enabled (not sure exactly which one caused it, but I'd guess
lockdep).  The kernel I ran into this with had a BSS of around 6.4 MB.

Unfortunately, uImage does not give us enough information to determine the
actual BSS size.  Increase the allowance to 18 MiB to give us plenty of
room.  Eventually this should be more intelligent, possibly packing
initrd+dtb at the end of guest RAM.

Alexander Graf 711934334e fdt: move dumpdtb interpretation code to device_tree.c
The dumpdtb code can be useful in more places than just for e500. Move it
to a generic place.

Alexander Graf 7e99826c35 Revert "PPC: e500: Use new MPIC dt format"
This reverts commit 518c7fb44f. It breaks
new Linux guests with SMP, because IPIs get mapped to large vectors which
our MPIC emulation does not implement.

Scott Wood e6eaabeb8d PPC: e500: split mpc8544ds machine from generic e500 code
Currently the only mpc8544ds-ism that is factored out is
toplevel compatible and model.  In the future the generic e500
code is expected to become more generic.

Scott Wood b330598137 PPC: e500: change internal references away from mpc8544ds
No functional changes -- machine is still outwardly mpc8544ds.

The references that are not changed contain mpc8544 hardware details that
need to be parameterized if/when a different e500 platform wants to
change them.

Scott Wood 4a18e7c92a PPC: e500: rename mpc8544ds into generic file
Rename the file (with no changes other than fixing up the header paths)
in preparation for refactoring into a generic e500 platform.  Also move
it into the newly created ppc/ directory.
