Julius Werner 808a429881 Makefile: Disable implicit rules
This patch disables implicit make rules (like %.o: %.c) from our build
system, since we don't use them and they can cause unexpected results
when there's a mistake in the Makefiles.

BRANCH=None
BUG=chromium:466469
TEST=emerge-falco coreboot fails with only this patch and succeeds with
this and the $(src-to-obj) fix.

Julius Werner a32b6f0b7d Makefile: Avoid duplicate class suffixes in $(call src-to-obj)
The build system uses the $(src-to-obj) function in multiple places to
figure out the corresponding output object file for a certan source
file, most importantly when generating the rule to build it. Usually
this is pretty simple, but some odd cases are a little tricky... such as
the auto-generated intermediary C files containing an array definition
generated from an ASL file. These files have already been compiled per
stage, so they contain the stage as a suffix and reside in the build
directory (e.g. build/.../dsdt.ramstage.c).

The previous $(src-to-obj) implementation just blindly appends the stage
again and turns this into build/.../dsdt.ramstage.ramstage.o. This isn't
very useful, so to avoid confusion this patch makes it strip additional
stage suffixes for those intermediary files.

This also fixes a bug with the ASL postprocessor, which didn't take this
double suffix into account: it added build/.../dsdt.ramstage.o to
ramstage-objs which should've been build/.../dsdt.ramstage.ramstage.o.
This only worked by accident because make compiled the file with its
implicit %.o: %.c rule instead.

BRANCH=none
BUG=chromium:466469
TEST=emerge-falco coreboot with the new make 4.1. Also build Falco and
Veyron_Jerry with make -r -R to make sure there are no other accidental
uses of implicit rules in our build system.

Julius Werner f97b88bee8 Makefile: Fix dependency tracking for ramstage objects
Dependency tracking in incremental builds is currently broken for the
ramstage, due to the intermediate linking step into one ramstage.o file
per directory. The original xxx.ramstage.o files are removed from
ramstage-objs, so they don't end up in allobjs and won't get translated
into DEPENDENCIES. This patch explicitly adds them to DEPENDENCIES
beforehand to resolve the issue.

BRANCH=None
BUG=None
TEST=Built, ran 'touch src/include/cbmem.h' and built again
incrementally. Confirmed that objects dependent on the modified header
such as timestamp.ramstage.o get rebuilt correctly.

Martin Roth d7689e4ad5 Doxygen: add a "simple" output config and make target
This is a doxygen target I'm using for cleaning up the coreboot doxygen
output.  It runs in about a minute instead of....  a lot longer, and
only generates documentation for the coreboot/src directory, excluding
vendorcode.

It was requested that the comments be stripped to make it easier to
read.  This was done through the following command (split for gerrit):

head -n 1 Doxyfile.coreboot_simple > Doxyfile.tmp ;
cat Doxyfile.coreboot_simple | sed 's|^\s*#.*$||' | sed '/^$/d' | sed 's|[[:space:]]\+$||' >> Doxyfile.tmp ;
mv Doxyfile.tmp Doxyfile.coreboot_simple

I'm including the command here because any time the file is updated
with the doxygen wizard, it will need to be run again.  It might be
desirable to turn this into a script in the documentation directory.

Gabe Black 51edd54738 ARM: Generalize armv7 as arm.
There are ARM systems which are essentially heterogeneous multicores where
some cores implement a different ARM architecture version than other cores. A
specific example is the tegra124 which boots on an ARMv4 coprocessor while
most code, including most of the firmware, runs on the main ARMv7 core. To
support SOCs like this, the plan is to generalize the ARM architecture so that
all versions are available, and an SOC/CPU can then select what architecture
variant should be used for each component of the firmware; bootblock,
romstage, and ramstage.

ARM: Split out ARMv7 code and make it possible to have other arch versions.

We don't always want to use ARMv7 code when building for ARM, so we should
separate out the ARMv7 code so it can be excluded, and also make it possible
to include code for some other version of the architecture instead, all per
build component for cases where we need more than one architecture version
at a time.

The tegra124 bootblock will ultimately need to be ARMv4, but until we have
some ARMv4 code to switch over to we can leave it set to ARMv7.

Patrick Georgi fadbe5f657 build: make scan-build work again
This drops the scan-build related Kconfig options
since it's now possible to simply run

    scan-build [-o outdir] make

and get coreboot built with its report.

There's also no inner make process anymore, and the way
things work should be clearer now.

Also adapt abuild to this new reality.

Furquan Shaikh 99ac98f7e1 Introduce stage-specific architecture for coreboot
Make all three coreboot stages (bootblock, romstage and ramstage) aware of the
architecture specific to that stage i.e. we will have CONFIG_ARCH variables for
each of the three stages. This allows us to have an SOC with any combination of
architectures and thus every stage can be made to run on a completely different
architecture independent of others. Thus, bootblock can have an x86 arch whereas
romstage and ramstage can have arm32 and arm64 arch respectively. These stage
specific CONFIG_ARCH_ variables enable us to select the proper set of toolchain
and compiler flags for every stage.

These options can be considered as either arch or modes eg: x86 running in
different modes or ARM having different arch types (v4, v7, v8). We have got rid
of the original CONFIG_ARCH option completely as every stage can have any
architecture of its own. Thus, almost all the components of coreboot are
identified as being part of one of the three stages (bootblock, romstage or
ramstage). The components which cannot be classified as such e.g. smm, rmodules
can have their own compiler toolset which is for now set to *_i386. Hence, all
special classes are treated in a similar way and the compiler toolset is defined
using create_class_compiler defined in Makefile.

In order to meet these requirements, changes have been made to CC, LD, OBJCOPY
and family to add CC_bootblock, CC_romstage, CC_ramstage and similarly others.
Additionally, CC_x86_32 and CC_armv7 handle all the special classes. All the
toolsets are defined using create_class_compiler.

Few additional macros have been introduced to identify the class to be used at
various points, e.g.: CC_$(class) derives the $(class) part from the name of
the stage being compiled.

We have also got rid of COREBOOT_COMPILER, COREBOOT_ASSEMBLER and COREBOOT_LINKER
as they do not make any sense for coreboot as a whole. All these attributes are
associated with each of the stages.

If xcompile can't find out suitable GCC compiler for i386/armv7, it
will not set $CC_i386/$CC_armv7 variable. Makefile sets $CC variable
from xcompile, and will print strange error messages when executing
$CC program if $CC is empty.

Add checking to avoid this problem. If $CC is empty, also delete
invalid .xcompile file, so Make can recreate this file next time.

Nico Huber 963bed546f Make: Use unaltered object list for dependency inclusion
It looks like the inclusion of dependency files was broken for all
ramstage objects since the list of those gets processed through the
ramstage-postprocess macro. Fix that by taking the unaltered list
for dependency files.

The output of `make printall` (look for DEPENDENCIES=) shows which
dependency files will be included.

Patrick Georgi 02ae0bf8fe build system: Don't run the full build system on "make clean"
When running "make clean" the build system used to parse the entire
build system. Besides costing time, it prevents cleaning the tree
if a blobs-board is selected but blobs are not enabled.

Instead, clean always removes all of $(obj) and .xcompile, while
distclean additionally removes .config and the like.

Besides cleaning up more completely (eg. dependency files), a side
effect is that this also removes $(obj)/util, if it exists
(default location for build tools).
