Vadim Bendebury 05a8472900 xcompile: improve mips toolchain handling
The mips toolchain used by coreboot so far comes from Chrome OS chroot
and is built explicitly for little endian code generation.

Other flavors of MIPS toolchain usually generate big endian code by
default and require command line options to switch to little endian
mode.

This patch adds another variable to the set of compiler flags examined
to determine compiler compatibility. This results in adding another
nested for loop in test_architecture(). To avoid the need to break
from different levels of nesting, processing of the successful case is
taken out from test_architecture().

With this change the Mentor Graphics provided mips GCC toolchain is
accepted by xcompile, resulting in the following output:

 ARCH_SUPPORTED+=mips
 SUBARCH_SUPPORTED+=mips mipsel
 CC_mips:=mips-linux-gnu-gcc
 CFLAGS_mips:= -Wno-unused-but-set-variable  -fno-stack-protector -Wl,--build-id=none -mno-abicalls -fno-pic -EL
 CPP_mips:=mips-linux-gnu-cpp
 AS_mips:=mips-linux-gnu-as

Vadim Bendebury d2cb1f93fb xcompile: Use local variables and make cosmetic changes
Declaring function variables local improves bash scripts' robustness.

Cosmetic changes among other things include renaming variables from
plural to singular and vice versa as appropriate, and replacing spaces
with tabs.

Tested by confirming that sorted output generated by
util/xcompile/xcompile is the same before and after the change.

Vadim Bendebury e469602461 make: avoid problems with mv aliases
Make fails to update .xcompile in case there is an mv alias preventing
silent overwrites of existing files. To avoid ambiguity, invoke mv
from standard location.

While we are at it, drop the code creating a unique .xcompile instance
before copying it into destination: this was done for the case of
running multiple independent make processes in parallel, but there is
a problem with this approach with multiple processes copying their
unique copies into the same destination file.

The tool running multiple make invocations in parallel should
explicitly invoke xcompile first.

Stefan Reinauer 13e4182119 kbuild: automatically include southbridges
This change switches all southbridge vendors and southbridges
to be autoincluded by Makefile.inc, rather than having to be
mentioned explicitly in southbridge/Makefile.inc or in
southbridge/<vendor>/Makefile.inc.

In order to be able to drop southbridge/amd/Makefile.inc, some
scattered source files had to be moved to a southbridge/amd/common
directory, in accordance to what we are doing on other architectures
already.

This means, vendor and southbridge directories are now "drop
in", e.g. be placed in the coreboot directory hierarchy
without having to modify any higher level coreboot files.

The long term plan is to enable out of tree components to be
built with a given coreboot version (given that the API did not
change).

Sol Boucher 057256541b cbfstool: Fix ability to add files at offsets near the end of empty spaces
Because cbfs_add_entry_at() previously *assumed* it would have to create a
trailing empty entry, it was impossible to add files at exact offsets close
enough to the end of an existing empty entry that they occupied the remainder
of its space. This addresses the problem by skipping the step of creating the
trailing empty entry if doing so would place it at the start offset of whatever
already followed the original empty section.

BUG=chromium:473511
TEST=Run the following commands:
$ ./cbfstool test.image create -s 0x100000 -m arm
$ dd if=/dev/zero of=twok.bin bs=1 count=2048

$ ./cbfstool test.image add -t 0x50 -f twok.bin -n near_end -b 0xfef80
$ ./cbfstool test.image print

Sol Boucher 0e53931fee cbfstool: Clean up in preparation for adding new files
This enables more warnings on the cbfstool codebase and fixes the
issues that surface as a result. A memory leak that used to occur
when compressing files with lzma is also found and fixed.
Finally, there are several fixes for the Makefile:
 - Its autodependencies used to be broken because the target for
   the .dependencies file was misnamed; this meant that Make
   didn't know how to rebuild the file, and so would silently
   skip the step of updating it before including it.
 - The ability to build to a custom output directory by defining
   the obj variable had bitrotted.
 - The default value of the obj variable was causing implicit
   rules not to apply when specifying a file as a target without
   providing a custom value for obj.
 - Add a distclean target for removing the .dependencies file.

In commit b0d8f5e9 I moved the call to cbmem_initialize()
in the CONFIG_EARLY_CBMEM_INIT case to the very beginning of

cbmem console driver in that it expects cbmemc_init() to be
called prior to cbmemc_reinit(). Therefore, ensure console
is called as the first thing even if some time is lost w.r.t.
timestamp tracking.

Vadim Bendebury 8ac8ffa318 i2c/ww_ring: change colors for different display modes

their values in decimal as opposed to hex.

Vadim Bendebury 89994226e8 i2c/ww_ring: use shorter blinking program
The originally loaded blinking program was written to allow gradual
change in LED brightness, which required controlling each LED with its
own engine. In fact there is no need in gradual brightness changes
when the firmware is controlling the ring. This allows to control all
LEDs by one engine, making the code simpler and more robust (no need
to synchronize the three engines any more).

BRANCH=storm
BUG=chrome-os-partner:36059
TEST=verified that recovery boot WW ring patterns work as expected.

Vadim Bendebury 420fb5eb3e i2c/ww_ring: stop running programs before loading the new ones
The two controllers on the ring are programmed independently, and if
the second controller is running the old pattern while the first one
was loaded with a new pattern, there is a window of when the two
unrelated patterns might interact.

To avoid this shut down execution on both controllers before starting
downloading the new pattern code.
