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.

1 # Our version of TCS211 binary libs has been compiled for a triband
2 # configuration that is a bastardized version of Leonardo quadband:
3 # while the same 3 TSPACT lines are used for antenna switch control,
4 # the correct line to be driven low for each band Rx & Tx operation
5 # is different in every case.
6 #
7 # This change in band Rx & Tx signal assignments was made in tpudrv12.h
8 # and got compiled into the tpudrv12 module in tpudrv.lib; the present
9 # patch restores the original quadband configuration.
