onboard wireless on rpi4

[Klaus Cucinauomo]

Hi Mark,

as far as I remember(didn’t work the last weeks on RPI-stuff)
the dma-thing only failed on GENERIC-NODEBUG (unexpected controller detection loops) …
But it worked on GENERIC and afaik Greg_unrelenting`s dma-fix isn’t yet merged to 13-current 
because of that unfixed issue…
(but you can apply his patch and test)..it should work under GENERIC without the 3GB-limit(4GB & 8GB-models)
