32 (when no alternative exists), Board Support Package (BSP) developments,
105 of Linux kernel development, BSP support, and release timing to select
131 with a mix of important new mainline, non-mainline, BSP developments and
136 kernels are used in leading edge feature and BSP development.
198 BSP-specific code additions are handled in a similar manner to
202 kernel type. From the perspective of the tools that create the BSP
203 branch, the BSP is really no different than a feature. Consequently, the
205 So again, rather than store the BSP twice, the team only stores the
206 unique differences for the BSP across the supported multiple kernels.
212 BSP-specific commits. In other words, the divisions of the kernel are
232 common to every kernel type and BSP that is organized further along in
240 three BSP-specific branches and a real-time kernel branch. Each branch
241 represents some unique functionality for the BSP or for a real-time
246 branches for individual BSP-specific real-time kernels. The illustration
249 apply to a given BSP.
