MIPS: ZBOOT: add missing include

2014-08-26T00:18:58+00:00

Commit dc4d7b37 (MIPS: ZBOOT: gather string functions into string.c)
moved the string related functions into a separate file, which might
cause the following build error, depending on the configuration:

| CC      arch/mips/boot/compressed/decompress.o
| In file included from linux/arch/mips/boot/compressed/../../../../lib/decompress_unxz.c:234:0,
|                  from linux/arch/mips/boot/compressed/decompress.c:67:
| linux/arch/mips/boot/compressed/../../../../lib/xz/xz_dec_stream.c: In function 'fill_temp':
| linux/arch/mips/boot/compressed/../../../../lib/xz/xz_dec_stream.c:162:2: error: implicit declaration of function 'memcpy' [-Werror=implicit-function-declaration]
| cc1: some warnings being treated as errors
| linux/scripts/Makefile.build:308: recipe for target 'arch/mips/boot/compressed/decompress.o' failed
| make[6]: *** [arch/mips/boot/compressed/decompress.o] Error 1
| linux/arch/mips/Makefile:308: recipe for target 'vmlinuz' failed

It does not fail with the standard configuration, as when
CONFIG_DYNAMIC_DEBUG is not enabled  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/
directory (see for example arch/x86/boot/string.h).

MIPS: ZBOOT: implement stack protector in compressed boot phase

2014-08-01T22:06:46+00:00

This patch implements the stack protector code in MIPS compressed boot
phase based on the same code added to arm in commit
8779657d29c0ebcc0c94ede4df2f497baf1b563f "stackprotector: Introduce
CONFIG_CC_STACKPROTECTOR_STRONG" by Kees Cook

mips: delete non-required instances of include

2014-01-24T21:39:56+00:00

None of these files are actually using any __init type directives
and hence don't need to include .  Most are just a
left over from __devinit and __cpuinit removal, or simply due to
code getting copied from one driver to the next.

MIPS: ZBOOT: gather string functions into string.c

2014-01-24T21:39:55+00:00

In the worst case this adds less then 128 bytes of code
but on the other hand this makes code organization more clear.

MIPS: ZBOOT: Support LZ4 compression scheme

2013-10-29T20:24:34+00:00

Add support for the LZ4 compression scheme in the ZBOOT decompression
stub, in order to support it we need to:

- select the "lz4" compression tool to compress the vmlinux.bin
  payload
- memcpy() is also required for decompress_unlz4.c so we share the
  implementation between GZIP, XZ and now LZ4

MIPS: ZBOOT: Define program header for text loadable segment

2013-10-29T20:24:30+00:00

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.

MIPS: ZBOOT: Support XZ compression scheme

2013-10-29T20:24:28+00:00

Add support for the XZ compression scheme in the ZBOOT decompression
stub, in order to support it we need to:

- select the "xzkern" compression tool to compress the vmlinux.bin
  payload
- link with ashldi3.o for xz_dec_run() to work
- memcpy() is also required for decompress_unxz.c so we share the
  implementation between GZIP and XZ

MIPS: Fix invalid symbolic link file

2013-09-19T15:04:35+00:00

Commit 3b29aa5ba204c [MIPS: add  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:

lrwxrwxrwx 1 maddy maddy 35 Sep 19 18:11 dt-bindings ->
