region info exposed via sysfs ?

[Mike Frysinger]

i see that while MEMGETINFO and MEMGETREGIONCOUNT are accessible via
sysfs, i cant find the equivalent for MEMGETREGIONINFO.  but i also
dont have any devices here that have numeraseregions > 0 as both my
physmap nor flashes and nand flashes all report numeraseregions == 0.

is it exposed via sysfs and i'm just not seeing it ?  or is this info
only available via the ioctl ?
