Hello,
For embedded devices where NAND flash is the only storage media, I was wondering what
are the existing approaches on how to store the device tree blob in flash.
Searching on the Internet I have found only two approaches:
1. Have a dedicated MTD partition for the device tree blob (raw).
2. Have a UBI volume on a partition and store the device tree blob as a file in a
UBIFS partition (this approach also stores the kernel image as a file in the same or
different volume).
Is anybody using other approach for storing the DTB in flash?
What method is more widely used in embedded devices?
Best regards,
--

Either if fine providing U-Boot (or whatever) is able to read it. Having
the data in a filesystem is probably more convenient.
