Lorekeeping: allow tpudrv-leonardo.lib on Leonardo/Tango
Back in 2015 the Mother's idea was to produce a FreeCalypso development
board that would be a clone of TI Leonardo, including the original
quadband RFFE; one major additional stipulation was that this board
needed to be able to run original unmodified TCS211-20070608 firmware
with all blobs intact, with only minimal binary patches to main.lib
and tpudrv.lib. The necessary patched libs were produced at that time
in the tcs211-patches repository.
That plan was changed and we produced FCDEV3B instead, with Openmoko's
triband RFFE instead of Leonardo quadband, but when FC Magnetite started
in 2016, a TPUDRV_blob= provision was still made, allowing the possibility
of patching OM's tpudrv.lib for a restored Leonardo RFFE.
Now in 2020 we have FC Tango which is essentially a verbatim clone of
Leonardo core, including the original quadband RFFE. We have also
deblobbed our firmware so much that we have absolutely no real need
for a blob version of tpudrv.lib - but I thought it would be neat to put
the ancient TPUDRV_blob= mechanism (classic config) to its originally
intended use, just for the heck of it.

The latest official firmware for Openmoko Neo1973 and Neo FreeRunner Calypso modems is moko13 as of this writing; moko13 is FreeCalypso Magnetite Hg changeset 286:840113655bbf built for the gtamodem target in the l1reconst configuration. There have been many changes in FC Magnetite since then, but few of them affect the l1reconst config on the gtamodem target in any noticeable way. The few noticeable post-moko13 changes which we do have in our current l1reconst code are not deemed important enough to justify making another formal release for a no-longer-made hardware platform that no longer has any real user community either. However, we also have the new TCS2/TCS3 hybrid config in which the old version of the G23M protocol stack from Openmoko (binary libs only, no source) has been replaced with a newer version from TI's TCS3/LoCosto program, and this new version is full source. This hybrid firmware has now reached the state where it is ready to be exercised by adventurous beta users in real-life usage. The new hybrid fw for the gtamodem target can be built as follows: ./configure.sh gtamodem hybrid cd build-gtamodem-hybrid; make Then after enduring the very slow build, you can flash it with fc-loadtool: loadtool> flash erase 0 0x250000 loadtool> flash program-bin 0 fwimage.bin If you are brave enough to do the above, please let us know how this new modem firmware fares when driven by QtMoko or SHR on the AP - it would definitely be an adventure! We would be most interested in working with developers or maintainers of specific AP software components that are directly responsible for talking AT commands to the modem, if there are any such developers or maintainers still around.
