188d3a278e [mips] Improve MIPS trampoline code
This patch fix trampoline build. inckern.S increases stack and calls _startC
of elf_trampoline, so inckern.S should be called before elf_trampoline. gcc4.2 puts
text (code) into image according to order of source files in this call, so order has changed.

In addition make will install trampoline kernel. It allows to use kernel for firmware build.

23df2d677f Revert this change. It broke the trampoline build. Until I'm sure
nothing else is broken, I'm reverting.

architectures.

ab2de2d795 Bump the version of config to the latest (3 year old, so upgrade
worries are long past). Also remove redundant MACHINE= declarations
and passing MACHINE/MACHINE_ARCH to module builds. That's now done in
common code.

about kernel module base address and actual size

f8e47016ec Don't build kernel.tramp on Octeon. Probably building it should be opt-in
not opt-out, but I don't know enough about which ports need it to get the
defaults right.

29a99755a9 FDT support for MIPS.
Add architecture specific files needed to compile MIPS with
flattened device tree support.

578828c8d2 Support compiling MIPS elf trampoline with a different ABI.
Allow changing the trampoline ABI with makeoptions, this will allow
us to have a trampoline with a different ABI from the kernel.
Useful in cases where we have to boot a 64 bit kernel from a
bootloader which supports only 32 bit or vice versa.

d048eaaca7 Make the ELF trampoline binary ELF executable (and do some cleanup).
- Remove the -shared flag for the trampoline binary, generate an
  ELF executable instead of a shared object.
- No need to generate tmphack.S,  move the code to sys/mips/mips/inckern.S
- No need generate opt_kernname.h, KERNNAME can be passed with -D

e8dce5b9b3 Complete the integration of tbemd branch into head.
TARGET_BIG_ENDIAN is now completely dead, except where it was
originally supposed to be used (internally in the toolchain building).

TARGET_ARCH has changed in three cases:
(1) Little endian mips has changed to mipsel.
(2) Big endian mips has changed to mipseb.
(3) Big endian arm has changed to armeb.

Some additional changes are needed to make 'make universe' work on arm
and mips after this change, so those are commented out for now.

UPDATING information will be forthcoming.  Any remaining rough edges
will be hammered out in -current.

Prefer PTR_LA over a naked la to work with 64-bits..

Use proper set of flags to build the tramp.  this gets 64-bit almost
building and lets me debug the 'almost' :)

Add in the emulation selection when linking...  We're still not 100%
of the way there, but we're better with it.  hack.so build now, but
we die when we try to link it in.

b0c90d8c3d Merge in the mips specific configuration files and such from the
merged juniper and mips2 code base.  This represents the work of
Juniper Engineers, plus Oleksandr Tymoshenko, Wojciech Koszek, Warner
Losh, Olivier Houchard, Randall Stewert and others that have
contributed to the mips2 and/or mips2-jnpr perforce branches.
