Progress of raspberry pi 4 aarch64 BSP

[Noor Aman]

Hello everyone,
I wanted to know about the status of raspberry pi 4 aarch64 bsp as I'm
thinking of this as my GSOC project. Where do I get started with? Any
specific member who deals with raspberry pi or arm architecture? What else
should I look into? Anything I should look into which would be helpful or
fruitful? Any help regarding this would be greatly appreciated. Thank you.

Regards,
