Seems like Marvell Bluetooth is not a standard one.
The support code for it in the Linux kernel is [1], while generic driver is [2].
Marvell uses a loadable firmware to bring the module to life.
The firmware seems to be shared between Wi-Fi and Bluetooth module.
Implementing firmware upload seems to be implementable using our standard firmware(9)
interface, so I will need to embed the firmware into the kernel.
I cannot use loadable modules because I boot my kernel via NFS.

Of course, Bluetooth support can be implemented only
when the SDIO infrastructure is ready, so this is the highest priority for me atm :-)
