Hi everybody,
when porting my router board from a mach-file based OpenWRT target to a
device-tree based target, I found that there is no generic way to create
a mtd_concat device from within the dts. The following patches attempt
to provide that possibility.
There's a fundamental issue with this patch series: DT is supposed to
represent the hardware, not how you want to use it, and clearly, your
concatenated MTD dev is a virtual device, not a real one, so I doubt it
will pass DT maintainers' review.
BTW, did you consider doing that through the command line?
Would you mind elaborating on that?
Something like:
mtdconcat=<virtdev1>=<realdev1>,<realdev2>;<virtdev2>=<realdev3>,<realdev4>
The biggest problem that I see is that I have to specify the fixed
partitions somewhere, and I would really like to keep that in the dts
file, where they would also be if it was only a single chip.
Send a v2, add the DT maintainers+ML in Cc, and you'll see what
happens.
I will do that. Thank you for your review and your input!
