In addition to supporting configuration fragments and patches, the
Yocto Project kernel tools also support rich
Metadata that you can
use to define complex policies and Board Support Package (BSP) support.
The purpose of the Metadata and the tools that manage it, known as
the kern-tools (kern-tools-native_git.bb
), is
to help you manage the complexity of the configuration and sources
used to support multiple BSPs and Linux kernel types.
