[ECOS] Porting a new flash driver

[Markus Schaber <schabi at logix-tt dot com>]

Hi,

I have a NAND flash controller hardware that seems not yet supported by
eCos, and example drivers (e. G. for openOCD) and documentation.

The aim is to use a small part of the flash via JFFS2 (and maybe RomFS).

Now I did not find much about flash drivers, block device drivers in
general, and the file systems in the eCos PDF documentation, the only
drivers discussed there seem to be network and serial. Is my assumption
correct that the eCos source is the best documentation here?

And concerning RomFS, it seems that it will only work with memory
mapped flash, but not with our NAND flash which can only be addressed
via the controller (PIO and DMA are possible). Is that correct?

Thanks a lot,
Markus
