this limitation now.

raspberrypi4-64.conf: Limit RAM to 3G
...
The PCI controller on the Raspberry Pi 4 acts as a DMA controller and can
only address the first 3Gb[1] of the memory space. On 32bit this was
addressed by implementing bouncing buffers[2] but this currently has no
support for arm64. In order to have working USB, as a workaround, we
limit the ram to 3G.
Fixes #446
