Introduce 'spec' subdirectories to outline aspects Instead of holding SPEC-variable dependent files and directories inline within the repository structure, move them into 'spec' subdirectories at the corresponding levels, e.g.: repos/base/include/spec repos/base/mk/spec repos/base/lib/mk/spec repos/base/src/core/spec ... Moreover, this commit removes the 'platform' directories. That term was used in an overloaded sense. All SPEC-relative 'platform' directories are now named 'spec'. Other files, like for instance those related to the kernel/architecture specific startup library, where moved from 'platform' directories to explicit, more meaningful places like e.g.: 'src/lib/startup'.

Add unified build directories to create_builddir This patch makes the benefit of the recently introduced unified Genode ABI available to developers by enabling the use of multiple kernels from within a single build directory. The create_builddir tool has gained a new set of kernel-agnostic platform arguments such as x86_32, or panda. Most build targets within directories are in principle compatible with all kernels that support the selected hardware platform. To execute a scenario via the run tool, one has to select the kernel to use by setting the 'KERNEL' argument in the build configuration (etc/build.conf). Alternatively, the 'KERNEL' can be specified as command-line argument of the Genode build system, e.g.: make run/log KERNEL=nova This allows us to easily switch from one kernel to another without rebuilding any Genode component except for the very few kernel-specific ones. The new version of the 'create_builddir' tool is still compatible with the old version. The old kernel-specific build directories can still be created. However, those variants will eventually be removed. Note that the commit removes the 'ports-foc' repository from the generated 'build.conf' files. As this is only meaningful for 'foc', I did not want to include it in the list of regular repositories (as visible in a 'x86_32' build directory). Hence, the repository must now be manually added in order to use L4Linux. Issue #2190 2016-12-21 08:16:12 +01:00			`include $(call select_from_repositories,mk/spec/x86.mk)`
