Can the fbtft driver still be used directly with Raspberry Pi 5B? #601

Now the Raspberry Pi has been updated to 5B. The previously configured SPI display on 4B cannot be used on 5B. When manually entering the "fbcp" command, the error "pi@raspberrypi:~ $ fbcp * failed to open vchiq instance" is displayed. To adapt to Raspberry Pi 5B, do you need to modify the fbtft driver? What specific changes need to be made?

fbcp uses dispmanx to copy the firmware framebuffer to fbtft. dispmanx is not supported on pi5: https://forums.raspberrypi.com/viewtopic.php?p=2138929#p2138929
