79d7cd31f9 MIPS: PNX8550: Move code one directory level up.
It was sharing the nxp directory but no code with pnx833x and will fit
better into the new platform makefile scheme, if moved.  Also after the
pnx833x code has been moved up, the pnx8550 Code was the last users of
the nxp dir.

5d25b01cf9 MIPS: Introduce support for Platform definitions
Move platform specific definitions to the platfrom directories.

Each platform shall do the following:
1) include an entry in arch/mips/Kbuild.platforms
2) add relevant definitions to arch/mips/<platform>/Platform

This commits changes ar7 to the new scheme as an example.

Introducing a platform speecific Platfrom file has following advantages:
1) decentralization of platfrom definitions
2) simplification af arch/mips/Makefile
3) force all platfrom to build with -Werror (done in arch/mips/Kbuild)

7326c4e567 MIPS: Tracing: Make function graph tracer work with -mmcount-ra-address
That thread "MIPS: Add option to pass return address location to
_mcount" from "David Daney <ddaney@caviumnetworks.com>" have added a new
option -mmcount-ra-address to gcc(4.5) for MIPS to transfer the location
of the return address to _mcount.

Benefit from this new feature, function graph tracer on MIPS will be
easier and safer to hijack the return address of the kernel function,
which will save some overhead and make the whole thing more reliable.

In this patch, at first, try to enable the option -mmcount-ra-address in
arch/mips/Makefile with cc-option, if gcc support it, it will be
enabled, otherwise, no side effect.

and then, we need to support this new option of gcc 4.5 and also support
the old gcc versions.

with _mcount in the old gcc versions, it's not easy to get the location
of return address(tracing: add function graph tracer support for MIPS),
   so, we do it in a C function: ftrace_get_parent_addr(ftrace.c), but
   with -mmcount-ra-address, only several instructions need to get what
   we want, so, I put into asm(mcount.S). and also, as the $12(t0) is
   used by -mmcount-ra-address for transferring the localtion of return
   address to _mcount, we need to save it into the stack and restore it
   when enabled dynamic function tracer, 'Cause we have called
   "ftrace_call" before "ftrace_graph_caller", which may destroy
   $12(t0).

(Thanks to David for providing that -mcount-ra-address and giving the
 idea of KBUILD_MCOUNT_RA_ADDRESS, both of them have made the whole
 thing more beautiful!)

d2bb076299 MIPS: Tracing: Add static function tracer support for MIPS
If -pg of gcc is enabled with CONFIG_FUNCTION_TRACER=y. a calling to
_mcount will be inserted into each kernel function. so, there is a
possibility to trace the kernel functions in _mcount.

This patch add the MIPS specific _mcount support for static function
tracing. by default, ftrace_trace_function is initialized as
ftrace_stub(an empty function), so, the default _mcount will introduce
very little overhead. after enabling ftrace in user-space, it will jump
to a real tracing function and do static function tracing for us.

and -ffunction-sections is incompatible with -pg, so, disable it when
ftracer is enabled.

6f7a251a25 MIPS: Loongson: Add basic Loongson 2F support
Loongson 2F has built-in DDR2 and PCI-X controller. The PCI-X controller
has a programming interface similiar to the the FPGA northbridge used on
Loongson 2E.

The main differences between Loongson 2E and Loongson 2F include:

1. Loongson 2F has an extra address window configuration module, which
   is used to map CPU address space to DDR or PCI address space, or map
   the PCI-DMA address space to DDR or LIO address space.

2. Loongson 2F supports 8 levels of software configurable CPu frequency
   which can be configured in the LOONGSON_CHIPCFG0 register.  The coming
   cpufreq and standby support are based on this feature.

Loongson.h abstracts the modules and corresponding methods are abstracted.

Add other Loongson-2F-specific source code including gcc 4.4 support, PCI
memory space, PCI IO space, DMA address.

1b93b3c3e9 MIPS: Add support for GZIP / BZIP2 / LZMA compressed kernel images
This patch helps to generate smaller kernel images for linux-MIPS,

Here is the effect when using lzma:

$ ls -sh vmlinux
7.1M vmlinux
$ ls -sh vmlinuz
1.5M vmlinuz

Have tested the 32bit kernel on Qemu/Malta and 64bit kernel on FuLoong
Mini PC. both of them work well. and also, tested by Alexander Clouter
on an AR7 based Linksys WAG54Gv2, and by Manuel Lauss on an Alchemy
board.

This -v2 version incorporate the feedback from Ralf, and add the
following changes:

1. add .ecoff, .bin, .erec format support
2. only enable it and the debug source code for the machines we tested
3. a dozen of fixups and cleanups

and if you want to enable it for your board, please try to select
SYS_SUPPORTS_ZBOOT for it, and if the board have an 16550 compatible
uart, you can select SYS_SUPPORTS_ZBOOT_UART16550 directly. and then
sending the relative patches to Ralf.

51b563fc93 arm, cris, mips, sparc, powerpc, um, xtensa: fix build with bash 4.0
Albin Tonnerre <albin.tonnerre@free-electrons.com> reported:

    Bash 4 filters out variables which contain a dot in them.
    This happends to be the case of CPPFLAGS_vmlinux.lds.
    This is rather unfortunate, as it now causes
    build failures when using SHELL=/bin/bash to compile,
    or when bash happens to be used by make (eg when it's /bin/sh)

Remove the common definition of CPPFLAGS_vmlinux.lds by
pushing relevant stuff to either Makefile.build or the
arch specific kernel/Makefile where we build the linker script.

This is also nice cleanup as we move the information out where
it is used.

Notes for the different architectures touched:

arm - we use an already exported symbol
cris - we use a config symbol aleady available
       [Not build tested]
mips - the jiffies complexity has moved to vmlinux.lds.S where we need it.
       Added a few variables to CPPFLAGS - they are only used by
       the linker script.
       [Not build tested]
powerpc - removed assignment that is not needed
          [not build tested]
sparc - simplified it using $(BITS)
um - introduced a few new exported variables to deal with this
xtensa - added options to CPP invocation
         [not build tested]

3702bba5eb MIPS: Loongson: Add GCC 4.4 support for Loongson2E
Because only gcc >=4.4 have loongson-specific support, we need to choose
the suitable -march argument for gcc <= 4.3 and gcc >= 4.4, and here, we
use -march=loongson2e for loongson2e.

Thanks goes to Arnaud Patard <apatard@mandriva.com> for suggestion of
using cc-options(Documentation/kbuild/makefiles.txt). and thanks Zhang
Le for introducing the new CPU_LOONGSON2E kernel option.

NOTE: -mtune option is not need if -march and -mtune use the same value.

85749d24bc MIPS: Loongson: Split common loongson source code out
To share common loongson source code between all of the loongson-based
machines. there is a need to split it out of the fuloong-2e/ directory.
at the same time, other according tuning is needed. the machine-specific
parts are defined as macros in relative header file, pci.h, mem.h,
machine.h.

8e4971175a MIPS: Loongson: Change naming methods
To make source code of loongson sharable to the machines(such as gdium)
made by the other companies, we rename arch/mips/lemote to
arch/mips/loongson, asm/mach-lemote to asm/mach-loongson, and rename lm2e
to the name of the machine: fuloong-2e. accordingly, FULONG are renamed to
FULOONG2E to make it distinguishable to the future FULOONG2F.  and also,
some other relative tuning is needed.

363c55cae5 MIPS: Add hibernation support
[Ralf: SMP support requires CPU hotplugging which MIPS currently doesn't
support.  As implemented in this patch cache and tlb flushing will also be
invoked with interrupts disabled so smp_call_function() will blow up in
charming ways.  So limit to !SMP.]
