This new tiffs utility is intended to replace the earlier mpffs-* utilities released in the summer of SE52 (A.D. 2013), and will also incorporate the additional examination functionality that was developed as part of the "pirollback" utilities. -Naming -====== - -I have previously referred to the FFS format in question as Mokopir-FFS or -MPFFS, from "Moko" and "Pirelli". I was originally hesitant to call it TIFFS, -as lacking the source code, I had no way of knowing whether the FFS format and -implementation were of TI's own invention, or something that TI licensed as a -black box from one of their many proprietary software partners. (I was unable -to identify it as any well-known, industry-standard FFS format, but absence of -evidence is not evidence of absence.) But now that we have TI's original source -code which implements this FFS (first the MV100-0.1.rar source, then the full -Leonardo one), complete with comments and a HISTORY file, we know that our FFS -was invented and implemented by someone named Mads Meisner-Jensen at TI - I'm -guessing in the SSA group in Nice, France. - -I am now making a naming transition from MPFFS to TIFFS: there is really no -link between this FFS format and the Openmoko+Pirelli duo, other than the -happenstance of me having first encountered this FFS on these two GSM device -brands, and the name TIFFS is more neutrally-descriptive. +See the abovementioned doc/TIFFS blurb for an explanation of the name change +from MPFFS to TIFFS.
