ubi layer tests (fastmap testing)

[Tanya Brokhman]

Hi Richard

You referred me to ubi-tests which were very helpful and discovered a 
bug in our driver. Thank you!
Unfortunately mtd-tests are not applicable to our driver.

I was wondering if there are any other ubi test I can run? Specially 
once concentrating on fastmap feature. How was it tested?

Thanks

Yay! :)

Why are mtd-tests not useable?

Fastmap was mostly tested with ubi-tests (to see whether the fastmap data structure can always be written do flash)
and by running many attach/detach cycles.
The critical part of fastmap happens at attach time. If fastmap fails to construct the EBA you'll have to find out
whether the on flash fastmap data structure is faulty (i.e. fastmap forgot to save some state) or fastmap interpreted the data
in a wrong manner.

BTW: It's awesome to see ongoing work on the still experimental fastmap feature. :-)

Thanks,
