Pushed to l2-mtd.git. Thanks!

Can this driver use the library memparse() function instead of
open-coding it?

[To answer myself:] I noticed this in drivers/mtd/devices/phram.c, which
prevents us from using memparse():

  /* By dwmw2 editorial decree, "ki", "Mi" or "Gi" are to be used. */

Are we (MTD) holding a revolutionary position against the standard
kernel libraries, which recognize [KkMmGg] prefixes, but not [kMG]i
prefixes? Should we extend memparse() to accept either form? Or would
doing so simply pollute the library and not really satisfy anyone?

[After more research:] It looks like this topic may be the subject of
some long-past flame wars. If I am digging up past demons, then I'd
prefer to let sleeping Balrogs lie.
