kernel-imximage.bbclass: Linux kernel with DCD headers
This new image type adds support to generate a Linux kernel with DCD
headers. Essentially it adds support to directly boot a Linux kernel
without a bootloader.
As the Linux kernel will be boot directly, it required that the Device
Tree is appended to the kernel image, which had support included in
OE-Core.
To have the Linux kernel generated with the DCD headers, following
steps must be followed:
- Linux kernel recipe must inherit kernel-imximage class;
- Device Tree appended Linux kernel must be used
(KERNEL_DEVICETREE_BUNDLE = "1");
- DCD header configuration must be provided (dcd.cfg or
dcd-<devicetree>.cfg);
