yocto-kernel: factor common routes, update to 2.6.37 and branch renaming
In order to extend and create more kernel recipes based on the supported yocto kernel common routines need to be placed in re-usable blocks. To accomplish this meta/recipes-kernel/linux/linux-yocto_git.bb is broken into three parts: - meta/classes/kernel-yocto.bbclass: contains common routines for checking out and configuring a yocto kernel git repository. This should be inherited by recipes that need this functionality. - meta/recipes-kernel/linux/linux-yocto.inc: Contains the machine mappings, compatibility, build directives and common task definitions for a yocto kernel based recipe. This inherits kernel-yocto, and is the typical point of entry for other recipes. - meta/recipes-kernel/linux/linuux-tools.inc: tasks and function definitions for kernel recipes that want to build/export perf It also updates the linux-yocto recipe to default to 2.6.37. As part of the update to 2.6.37 the branch naming and conventions have been modified to show inheritance, and be more generic. For example: master meta yocto/base yocto/standard/arm_versatile_926ejs yocto/standard/base yocto/standard/beagleboard yocto/standard/common_pc/atom-pc yocto/standard/common_pc/base yocto/standard/common_pc_64 yocto/standard/fsl-mpc8315e-rdb yocto/standard/intel_atom_z530 yocto/standard/intel_core_qm57_pch yocto/standard/mti_malta32_be yocto/standard/preempt_rt/base yocto/standard/preempt_rt/common_pc yocto/standard/preempt_rt/common_pc_64 yocto/standard/preempt_rt/intel_atom_z530 yocto/standard/preempt_rt/intel_core_qm57_pch yocto/standard/qemu_ppc32 yocto/standard/routerstationpro In this structure: master: tracks the mainline kernel meta: meta information for the BSPs and kernel features yocto/base: baseline kernel branch yocto/standard/base: 'standard' kernel, contains features and configs for all BSPs yocto/standard/<machine>: represents a BSP with specific features or configurations The tools, tree and libc-headers have all been updated to deal with this new structure. Also in addition to dealing with the new structure, they continue to work with the existing tree and will adapt at runtime to the differences. The linux-yocto-stable_git.bb recipe continues to build the 2.6.34 based tree,and linux-yocto_git.bb builds 2.6.37. As boards are enabled for the new kernel they will move from -stable to the development kernel. As of now, only the emulated targets have moved to 2.6.37-rcX Signed-off-by: Bruce Ashfield <bruce.ashfield@windriver.com>
