I'm having trouble figuring out how to embed a dtb file into my
kernel. I'm thinking that there should be a standard, architecture
independent facility for this akin to initramfs, yes?
Could someone please either point me to the standard facility,
relevant doc, a currently building board that uses the standard
facility, or outline what needs to be done to do this with a new board?
If it matters, (I can't think why it would), I'm working with powerpc
on a 3.10 kernel. But if there are better facilities in other
versions I'd appreciate hearing about that too.
Thank you in advance.
Hi,
The device tree (DTB file) is not supposed to be embedded into the
kernel but loaded independently by the boot loader (for instance Uboot).
Then a pointer to the device tree is handed over by Uboot to the kernel
when calling the _start function.
You also have in arch/powerpc/boot/ a facility called cuboot which
allows to create a ppcboot image with kernel and device tree bound together.
