Leaf Hill BSP has specific kernel configuration in yocto-kernel-cache for kernel v4.1. We found some issue where we can't overwrite the existing kernel configs in yocto-kernel-cache from developer's custom meta layer.
Root cause analysis has shown that the usage of KERNEL_FEATURES in kernel recipes and local.conf to pick up BSP specific configs from kernel-meta is inappropriate. KERNEL_FEATURES should always and only used for adding configuration or features to the build. A new variable "BSP_SUBTYPE" has been created to resolve this issue.
