Nico Huber 66cc843f3d libpayload: Revive ffs()
Revive ffs() in a more fancy way (that is more likely to be accepted).
We dropped it in
  7a8a4ab lib: Unify log2() and related functions
but there is at least one user: flashrom.

Aaron Durbin 94a74998c0 endian: add portable endian functions
The current endian API support in coreboot doesn't follow
any known API that can be shared in userland as well as coreboot
proper. To that end provide big and little endian helper functions
that can be used in code that can be shared within coreboot proper
and userland tools.

Aaron Durbin 789f2b6c43 fsp1_1: provide binding to UEFI version
FSP has some unique attributes which makes integration
cumbersome:

1. FSP header files do not include the types they need. Like
   EDKII development it's expected types are provided by the
   build system. Therefore, one needs to include the proper
   files to avoid compilation issues.
2. An implementation of FSP for a chipset may use different
   versions of the UEFI PI spec implementation. EDKII is a
   proxy for all of UEFI specifications. In order to provide
   flexibility one needs to binding a set of types and
   structures from an UEFI PI implementation.
3. Each chipset FSP 1.1 implementation has a FspUpdVpd.h
   file which defines it's own types. Commonality between
   FSP chipset implementations are only named typedef
   structs. The fields within are not consistent. And
   because of FSP's insistence on typedefs it makes it
   near impossible to forward declare structs.

The above 3 means one needs to include the correct UEFI
type bindings when working with FSP. The current
implementation had the SoC picking include paths in the
edk2 directory and using a bare <uefi_types.h> include.
Also, with the prior fsp_util.h implementation the SoC's
FSP FspUpdVpd.h header file was required since for providing
all the types at once (Generic FSP 1.1 and SoC types).

The binding has been changed in the following manner:
1. CONFIG_UEFI_2_4_BINDING option added which FSP 1.1
   selects. No other bindings are currently available,
   but this provides the policy.
2. Based on CONFIG_UEFI_2_4_BINDING the proper include
   paths are added to the CPPFLAGS_common.
3. SoC Makefile.inc does not bind UEFI types nor does
   it adjust CPPFLAGS_common in any way.
4. Provide a include/fsp directory under fsp1_1 and
   expose src/drivers/intel/fsp1_1/include in the
   include path. This split can allow a version 2,
   for example, FSP to provide its own include files.
   Yes, that means there needs to be consistency in
   APIs, however that's not this patch.
5. Provide a way for code to differentiate the FSP spec
   types (fsp/api.h) from the chipset FSP types
   (fsp/soc_binding.h). This allows for code re-use that
   doesn't need the chipset types to be defined such as
   the FSP relocation code.

Nico Huber 135ca51314 crossgcc: Preparations for building Ada frontend
As with most other languages, a pre-installed Ada toolchain is needed
to build gcc's Ada frontend. To support building with older host tool-
chains, the patch `gcc-5.2.0_gnat.patch` disables warnings for unknown
pragmas. Building has been tested with host gcc-4.9 and hopefully works
with newer versions, too.

For convenience, the gnattools (e.g. gnatmake etc.) will be build if
'ada' is specified as a target language.

Though coreboot started as x86 only, the current approach to x86
linking is out of the norm with respect to other architectures.
To start alleviating that the way ramstage is linked is partially
unified. A new file, program.ld, was added to provide a common way
to link stages by deferring to per-stage architectural overrides.
The previous ramstage.ld is no longer required.

Note that this change doesn't handle RELOCATABLE_RAMSTAGE
because that is handled by rmodule.ld. Future convergence
can be achieved, but for the time being that's being left out.

Martin Roth 0f045a69b8 intel/model_2065x/Kconfig: Don't use LAPIC_MONOTONIC_TIMER
The LAPIC_MONOTONIC_TIMER symbol doesn't do anything in the code
unless UDELAY_LAPIC is selected.  Since this chip uses UDELAY_TSC,
LAPIC_MONOTONIC_TIMER generates a Kconfig warning and should be
removed.

Aaron Durbin d2cd7f6c6a x86: remove unused sections from romstage.ld
Now that the only source of ELF sections for romstage are
from directly included .inc files or ROMCC generated inc
files the subsection globs can be removed. i.e. Remove
.rom.data.* and .rom.text.* listings. Lastly, put the
.rom.data section directly after the .rom.text. They
are by definition read-only and they are generated from
the same place.

BUG=chrome-os-partner:44827
BRANCH=None
TEST=Spot checked !ROMCC and ROMCC boards. Confirmed
     only .rom.text .rom.data sections exist.

Aaron Durbin e581b067ca x86: add romstage.S to bind program flow and ordering
The build system was previously determining the flow
of the romstage code by the order of files added to
the crt0s make variable. Those files were then
concatenated together, and the resulting file was added
to the build dependencies for romstage proper.

Now romstage.S is added that can be built using
the default object file rules. The generated
romstage.inc is pulled in by way of an #include in the
newly added romstage.S.

BRANCH=None
TEST=Built vortex, rambi, and some asus boards. compared
     readelf -e output.

Aaron Durbin 85982cd4a2 x86: don't create MAINBOARDDIR/romstage.inc for !ROMCC boards
Previously, the x86 romstage build process was unconditionally
creating a romstage.inc and adding it to crt0s. This step is
inherently not necessary in the !ROMCC case becaue the romstage.inc
was created by the compiler outputting assembler. That means
MAINBOARDDIR/romstage.c is truly a C environment that requires
some sort of assembler stub to call into (cache_as_ram.inc from
the chipset dirs). Therefore, remove this processing. The result
is that MAINBOARDDIR/romstage.c can use the normal build steps
in creating an object and linking. The layout of romstage.elf
will change but that's only from a symbol perspective.

BUG=chrome-os-partner:44827
BRANCH=None
TEST=Built multitude of boards. Compared readelf -e output.
