Boris Brezillon e25f6e9024 Add a tool to generate raw NAND images 
Generating raw NAND images is particularly useful for boot0 images
creation since the mainline driver is not supporting the funky layout
used by Allwinner's ROM code to load the boot0 binary from NAND.

This tools also allows one to generate raw images for 'normal' partitions
so that they can be flashed before soldering on the NAND on the board
(using a regular NAND programmer).

The tool takes care of generating ECC bytes and randomizing data as
expected by the NAND controller, and re-arranging the ECC/data sections
correctly.
