UBI Fastmap support is stable in the 4.4 kernel so lets take
advantage of it to shave off 5-10 seconds of boot time.

Hi Tim,
Shouldn't this patch also enable the required kernel symbol?
(MTD_UBI_FASTMAP)

Important: this feature is experimental so far and the on-flash │

Will it leave Experimental state in the near future?
Thanks,
Koen
