Most of the supported chips use legacy (non-DT) bootloaders, so they will
need to select an appropriate builtin DTB at compile time until the
bootloader is updated. Provide suitable DTS files, and a means to compile
one of them into the kernel image.

Platforms which use raw zboot images may need to link the image at
a fixed address if there is no other way to communicate the load
address to the bootloader. Allow the per-platform Kbuild files
to specify an optional zboot image load address (zload-y) and fall
back to calc_vmlinuz_load_addr if unset.

Pull MIPS updates from Ralf Baechle:
"This is the main pull request for MIPS:
- a number of fixes that didn't make the 3.19 release.
- a number of cleanups.
- preliminary support for Cavium's Octeon 3 SOCs which feature up to
48 MIPS64 R3 cores with FPU and hardware virtualization.
- support for MIPS R6 processors.
Revision 6 of the MIPS architecture is a major revision of the MIPS
architecture which does away with many of original sins of the
architecture such as branch delay slots. This and other changes in
R6 require major changes throughout the entire MIPS core
architecture code and make up for the lion share of this pull
request.
- finally some preparatory work for eXtendend Physical Address
support, which allows support of up to 40 bit of physical address
space on 32 bit processors"
[ Ahh, MIPS can't leave the PAE brain damage alone. It's like
every CPU architect has to make that mistake, but pee in the snow
by changing the TLA. But whether it's called PAE, LPAE or XPA,
it's horrid crud - Linus ]

Allow more compression algorithms as well as uncompressed uImage.bin

problems in the decompression code in the bootloader or even speed

It does not fail with the standard configuration, as when
CONFIG_DYNAMIC_DEBUG is not enabled <linux/string.h> gets included in
include/linux/dynamic_debug.h. There might be other ways for it to
get indirectly included.
We can't add the include directly in xz_dec_stream.c as some
architectures might want to use a different version for the boot/

There is currently no corresponding ELF program header for the "text"
loadable segment which is confusing for some bootloader out there such
as CFE because it expects to find a program header matching the segment
it is trying to load. The Linux kernel ELF binary "vmlinux" has a
similar program header for the text segment so we just mimic this here
too.

Commit 3b29aa5ba204c [MIPS: add <dt-bindings/> symlink] created a symlink
file in include/dt-bindings. Even though commit diff is fine, the symlink
is invalid and ls -lb shows a newline character at the end of the filename:

Add a uImage build target for MIPS, which builds uImage.gz (a U-Boot
image of vmlinux.bin.gz), and then symlinks it to uImage. This allows
for the use of other compression algorithms in future, and is how a few
other architectures do it.
It's enabled conditionally on load-y >= 0xffffffff80000000 which
hopefully allows 64bit kernels to also work as long as the load and
entry address can be represented by the 32bit addresses in the U-Boot
image format.

The vmlinux load address and entry address is calculated in multiple
places:
- arch/mips/Makefile defines load-y from CONFIG_PHYSICAL_START (or
defined by the platform) and passes it to
arch/mips/boot/compressed/Makefile.
- arch/mips/boot/compressed/Makefile calculates kernel entry using nm.
- arch/mips/lasat/image/Makefile calculates both load and entry address
using nm.
Lets combine these in the main Makefile and then pass them as Make
parameters to each of the three boot image Makefiles (in boot/,
boot/compressed, lasat/image/). The boot/ Makefile doesn't currently use
them, but will soon need to for U-Boot image targets.
The existing load-y definition is used in preference to calculating the
load address using nm.

Add symlink to include/dt-bindings from arch/mips/boot/dts/include/ to
match the ones in ARM and Meta architectures so that preprocessed device
tree files can include various useful constant definitions.
See commit c58299a (kbuild: create an "include chroot" for DT bindings)
merged in v3.10-rc1 for details.
MIPS structures it's dts files a little differently to other
architectures, having a separate dts directory for each SoC/platform,
but most of the definitions in the dt-bindings/ directory are common so
for now lets just have a single "include chroot" for all MIPS platforms.

When building with -fstack-protector, gcc emits the __stack_chk_guard and
__stack_chk_fail symbols to check for stack stability. These symbols are
defined in vmlinux but the generated vmlinux.bin that is used to create
the compressed vmlinuz image has no symbol table so the linker can't find
these symbols during the final linking phase. As a result of which, we
need either to redefine these symbols just for the compressed image or drop
the -fstack-protector option when building the compressed image. This patch
implements the latter of two options.
Fixes the following linking problem:
dbg.c:(.text+0x7c): undefined reference to `__stack_chk_guard'
dbg.c:(.text+0x80): undefined reference to `__stack_chk_guard'
dbg.c:(.text+0xd4): undefined reference to `__stack_chk_guard'
dbg.c:(.text+0xec): undefined reference to `__stack_chk_fail'
[[email protected]: I'm applying this before the patch that actually adds
stack protector support for MIPS. This means, it will not be possible
to trigger above error message with any commit from the tree but rather
they are what one would hit without this commit.]
