#1677150 — [PATCH v4 0/9] mtd: sharpslpart partition parser

This patchset introduces a simple partition parser for the Sharp SL
Series PXA handhelds. More details in the commit text.

I have set in cc the ARM PXA maintainers because this is the MTD part of
a planned wider patchset cleaning the Zaurus board files. The MFD maintainers
are also in cc (tmio.h change).

Changelog:
v1 initial import of 2.4 sources [1]
v2 refactor applying many suggested fixes [2]
v3 put the partition parser types in the platform data [3]
v4 refactor after ML review [4]
