* Initial commit - wip
* Half part of the transition of baseband processor.
* More SGD
* WIP, Weather refactor, UI improv
* Rename
* Added 4msps, and fixes
* Fixes
* princeton working
* Renamed proc_weather, bc now multifunctional
* Proto: bett
* FPS_CAME = 4,
FPS_PRASTEL = 5,
FPS_AIRFORCE = 6,
* Came Atomo, fixes
* Separate weather and sgd, bc of baseband size limit
* Fix display
* Save space
* More protos
* Dooya proto added
* More protos
* add protos
* More protos
* Move weather to ext app
* nw
* Revert "Move weather to ext app"
This reverts commit 8a84aac2f5.
