You need my local patches. Nick Hudson wanted to adjust them before they
could be committed. There is also a qirk with the SD interface that would
break other hardware.

RPI4 is aarch64 only. In theory you could run a 32bit system, but
it would be limited in memory and couldn't use USB (the PCIe link
sits in 64bit space). Linux supports the ARM variant of PAE to handle
an extended address space in 32bit mode, we don't.
