One thing confuses me is the output file. My understand is we will use
u-boot-with-dtb.bin file. Other files are intermediate files. It would
be helpful to explain each output file, especially for debugging, and
let other know we switch from one file to another after this patch set.
CONFIG_OF_SEPARATE seems not be selected explicitly anywhere. Are we
relying on the first choice to be selected automatically? Is it guaranteed?
