2# Linux kernel with DCD headers
3#
4# This new image type adds support to generate a Linux kernel with DCD
5# headers. Essentially it adds support to directly boot a Linux kernel
6# without a bootloader.
7#
8# As the Linux kernel will be boot directly, it required that the Device
9# Tree is appended to the kernel image. To have the Linux kernel
10# generated with the DCD headers, following steps must be followed:
11#
12# - Linux kernel recipe must inherit kernel-imximage class;
13# - Device Tree appended Linux kernel must be used
14# (KERNEL_DEVICETREE_BUNDLE = "1");
15# - DCD header configuration must be provided (dcd.cfg or
16# dcd-<devicetree>.cfg);
