If you have an embedded board with a proper DT definition, and the
UART is hard-wired to the Bluetooth chip, then go for serdev. It
means no btattach is needed. The kernel will enumerate this properly
for you. That is the way forward. Someone needed to adapt the
hci_bcm.c driver for this anyway. It just happens that you are the
first one.

Right - I'll follow that route and add serdev support to hci_bcm.c then!

Hmm. ok, this gets to be a bitof a rabbit-hole.

the hci-nokia driver is *extremely* similar in operation to the hci_bcm
driver, other than being serdev based. even the firmware loading is
"broadcom style", so I dont really see why it needs another driver,
other than its been coded to one chip and a few small nokia-specific
bits in it.

It seems there is a fair bit of commonality among the h4 based bluetooth
drivers - probably better to abstract it out and make a h4 core around
which the other serdev and ldisc drivers could sit?

I'll have a look at that on Monday.
