onboard wireless on rpi4

[Klaus Cucinauomo]

the SDIO-implementation is „disfunctional" and misses some necessary requirements…
brcm wifi-drivers have to use external source-files and to translate nvram to detect 
the different chipsets. It’s even possible that external sources differ from version to version of the same board.
All that is NOT implemented in the existing SDIO-„idea“ which only tries to „scan" 
the hardware via the CAM-framework. A thing called SDIO-tool fails because of that(does nothing).
I cannot promise (because of many other things to do) but  perhaps would be willing to invest time to implement the drivers … 
(! but only  if REALLY no one else is currently working on it. ! - to prevent double work and waste of time.. ) .
I guess(same as with the gnet-driver) the starting point is an existing driver-framework, in this case OpenBSD( 
in approximately I know how it works because I worked a little with the devs in the past).

Regards

Klaus
