From: Tom Rini <trini@kernel.crashing.org>
PPC32: Select arch/ppc/kernel/head.S on CONFIG_PPC_STD_MMU.
- Don't pick a head*.S by default, instead select head.S on
CONFIG_PPC_STD_MMU. This is more consistent with how we
case things in this file.

This has three main parts: (1) support for the 440GP and 440GX processors,
(2) support for the "Ebony" and "Ocotea" reference boards for those processors,
and (3) support for 64-bit physical addresses. The 440GP and 440GX are "Book E"
processors, and this introduces a CONFIG_BOOKE and some definitions that apply
to all Book E processors.
Having 64-bit physical addresses means that PTEs are now 64 bits. The PTE pages
stay at 4kB, and the pgdir expands to 8kB.

Currently, vmlinux.lds.s is generated by the top-level Makefile.
Unfortunately, this causes the automatic CONFIG dependencies to
not work correctly, the reason being that make caches the timestamps
of include/config/* so even after split-include updated the
timestamps, make still uses the cached stamps to decide whether to
rebuild vmlinux.lds.s.
The simple fix is to move generation of vmlinux.lds.s into the
arch/$(ARCH)/kernel subdirectories, where we build other files
for the final link (like head.o) anyway. This also means some
special code in the top-level Makefile for preprocessing can go
away, since we now just use the standard rules during the recursive
phase.
This patches fixes up all archs for this change (untested).

EXTRA_TARGETS has been overloaded with functionality.
This is now split in two:
targets := list targets kbuild did not know of otherwise
extra-y := list targets to be build when not building modules only.
extra-y is mainly used to list .o files that is not to be included
in the fnal built-in.o file for a directory.

One of the goals of the whole new modversions implementation:
export-objs is gone for good!

All the iSeries machines that can run Linux are 64-bit PowerPC
machines and are now supported by the ppc64 kernel. Since no-one
is interested in maintaining the iSeries support in the ppc32
kernel, I am removing it.

Makefiles no longer need to include Rules.make, which is currently an
empty file. This patch removes it from the arch tree Makefiles.

This changeset moves all "system library" code to this directory.
System library code includes all common libraries
of routines (PIC, system controller, host bridge, kernel feature
enablement are all examples of things that belong here). The existing
arch/ppc/kernel/ directory keeps all "core" CPU support. Cache
handling, basic cpu startup, tlb manipulation, and core kernel
code all belong here. The arch/ppc/platforms/ directory now
contains only platform family specific files. For SoC processors
this includes the OCP glue-code that defines an SoC family.
|
|
This also puts the file in include/asm-ppc/offsets.h rather
than arch/ppc/kernel/asm-offsets.h. This changes PPC to do things
similarly to other ports, and makes make -j work reliably.

The tags were slightly useful when the kernel maintainers weren't
using BK, but these days they are more trouble than they are worth.
They tend to cause patch rejects, and often end up getting turned
into the fixed form (rather than the %x% tag form).

Many Makefiles did a put an own rule in front of
"include $(TOPDIR)/Rules.make" for no good reason at all,
the only places where it made sense are converted to using
EXTRA_TARGETS now.

CONFIG_4xx but which won't apply on the new 440GP has been changed
to depend on CONFIG_40x instead. Also a few other fixes and updates
for 405GP-based systems from the linuxppc_2_4_devel tree.
