In the past few days I've tested the flash code in -current on a
GlobalScale DreamPlug (arm platform), and confirmed that the low-level
part of the code is working. I can read the flash on the unit and
identify the existing partitions and data within them (but the main
partition is formatted as UBI fs, so I've only looked at it with hexdump
so far). I haven't tried the nandfs layer yet, or writing to the flash.
