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.
