2015-05-08make: support absolute and relative obj= specificationsVadim Bendebury
There has been a problem with out of tree build directories specified using relative paths, as in $ make obj=../build/peppy while specifying full path to obj works fine. This patch fixes the problem, making sure that make's path manipulation string substitute command is applied to both source and build roots. To test this ran the following script echo > /tmp/build.log for build_root in ./ ../ ''; do build_dirs="${build_root}build/peppy" if [ -n "${build_root}" ]; then build_dirs+=" $(realpath ${build_root})/build/peppy" fi for build_dir in ${build_dirs}; do rm -rf $build_dir .config* build* ../build* make obj=${build_dir} menuconfig # configure for google peppy board echo "building in ${build_dir}" >> /tmp/build.log if ! make obj=${build_dir}; then exit fi done done and then checked the generated file: $ cat /tmp/build.log building in ./build/peppy building in /home/vbendeb/old_projects/coreboot/source_code/build/peppy building in ../build/peppy building in /home/vbendeb/old_projects/coreboot/build/peppy building in build/peppy Change-Id: If46b046108e906796fe84716e93bf341b3785f14 Signed-off-by: Vadim Bendebury <vbendeb@chromium.org> Reviewed-on: http://review.coreboot.org/10127 Tested-by: build bot (Jenkins) Reviewed-by: Patrick Georgi <pgeorgi@google.com>
2015-04-28make: avoid problems with mv aliasesVadim Bendebury
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.

2015-04-22Makefile: Avoid duplicate class suffixes in $(call src-to-obj)Julius Werner
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.

2015-04-17Makefile: Fix dependency tracking for ramstage objectsJulius Werner
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.

2015-01-08Doxygen: add a "simple" output config and make targetMartin Roth
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.

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.

2014-05-06Introduce stage-specific architecture for corebootFurquan Shaikh
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.

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.

2013-02-12build system: Don't run the full build system on "make clean"Patrick Georgi
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).
