Hi Richard,
Yes, mostly. It's different from MTD, in that all flash is exposed
through a linear address space, from which the FTL is layered on top.
This allows the device to still do some work, such as ECC, RAID, etc. if
it choose to, but also allows the host to do it.
I think UBI could be a good choice for maintaining each of the flash
"partitions" as there's a lot of small subtle details that have to be
taken care of.
