89254cb612 rknanoutils: add raw encode mode, add header fields
The raw encode mode allows to use the raw encode_page routine on
any file which proved to be useful. The guessed fields of the
headers are based on some rk2918 headers which leaked. They are
mainly informative though (date, version, chip).

906963ae76 rknanoutils: much more sensible format guess
I finally found a sensible format for the executable files.
The tool now can output the loading entry to elf files. Some
disassembly and analysis suggest the phys/virt addresses are
correct. However the entries are somehow linked and it is
still unclear how (are there "calls" to the code ? when ?).

d6bbe39dc6 rknanoutils: more reverse engineering of the BOOT format.
I found out that the file has a number of "entries", in
3 categories. The third category seem to contain bootable files.
In the RKnano firmware file I have, these entries are named
"NandBoot1" and "NandBoot2". They seem to use the same format as
the stage3 of the RKnanoFW format but we do not understand this
format precisely for now anyway.
