For the RK356x [1] and for RK3588 in u-boot [2] the pci_addr range was
changed to be in 32-bit address space, start address at 0x40000000, to
make the 1 GB region available for 32-bit BARs. Something that possible
could/should be done here too?
E.g.:
<0x03000000 0x0 0x40000000 0x9 0x80000000 0x0 0x40000000>
