Mini U-Boot is running out of OCM and it's only purpose is to program non
volatile memories. There are different configurations which ospi/qspi can
be that's why describe them via DT.
DT binding is already approved that's why there is no reason not to add it.

Support for dual-stacked/parallel configuration is here:
