The are several advantages to use the yocto recipe as base:
- The checkout of the git repo is done differently: it makes the
do_fetch task faster than it would be with the default behavior which
is to clone the entire repository.
- It is possible to share part of the build process by defining the
KMACHINE variable: All machines with the same KMACHINE value will
share (at least part of) the build environment, speeding up compile
time.
- It is possible to conditionally add configs through the
KERNEL_FEATURES variable, without needing to rebuild from scratch when
changing the features.
The new recipe also directly takes advantage of the KERNEL_FEATURES to
add support for init ram disks.
A another change happening with this commit is the kernel modules to
autoload being defined in a single file and (as the defconfig) depend on
the SOC_FAMILY variable (sitara or armada).
