Hello,

I'd be thankful for a second review after the big changes from v1
which was just a proof of concept.
As for the memory management, it totally mimics the other parsers.

The patch has been backported to 4.4 [1] and up to 3.10 [2] with
minimal changes to module init/exit:
since linux 4.5 (commit b8f70ba mtd: kill off MTD partition parser
boilerplate) we use module_mtd_part_parser().

With this parser we have finally a single linux-as bootloader kernel
covering the 4 Zaurus pxa 27x devices (repartitioned or not).

Thanks in advance
Andrea
