Some information, docs and code about the BCM GNSS of the Thinkpad Tablet
10. Nothing is working so don't expect anything.

The BCM4752 is a raw GNSS receiver, i.e. it does not calculate the GPS
solution on its own but rather outputs the raw receiver signal so that a
userspace library can calculate it. This is kind of nice and offers freedoms
you usually not have but the protocol is completely undocumented.

Similar chipsets are made by Infineon and some others using a similar
protocol. Some information can be found on the net but up to now I did not
find anything working or any specs to code something.
