We currently keep track of regions with the SDRAM by requesting a struct resource from the memory bank. We will make additional use of that to request memory handed out to EFI applications when barebox is being used as EFI loader.
For that purpose, we need an easy way to walk the requested memory region and especially the gaps between them as well as support for freeing partial regions.
