We want to have jffs2 running on a part (some megabytes / one FIS
partition) of the NAND flash, to store configuration and theming data.

I'm currently reading the sources, and it seems ugly, but doable.

Ugly, because it looks like the flash driver interface consists of some
static functions, so it will be impossible to support different flashes
concurrently. Luckily, we'll only need a single flash unit at the
