Liberate the bcm4334 wifi/bluetooth firmware
The driver for this chip seems to already be free software and is in the mainline linux kernel: https://redmine.replicant.us/issues/1836
Cypress now owns the rights to the bcm4334 chips' firmware. To my knowledge, Cypress is more likely to say yes to a request that they release the source code to this firmware with a free software license than Broadcom would have been. I don't believe anyone has formally asked Cypress to do this. Since this chip is in a lot of Replicant's supported devices, it would make sense for our project to formally ask this of them.
The non-free firmware binary seems to be available here:
There were some efforts to hack this chip's firmware in the past, but it seems to not have gone anywhere...
Some of this work seems to have been done by this developer, who we could maybe contact for help if we also want to hack the chip's firmware: https://github.com/shoote email@example.com
