[PATCH 0/6] resource: add support for walking resource gaps

[Ahmad Fatoum]

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.

Ahmad Fatoum (6):
  resource: implement resource walker
  test: self: implement resource walker selftest
  commands: iomem: add support for printing gaps
  test: py: add test for valid JSON output from iomem/clk_dump
  memory: add helpers for iterating over memory regions
  resource: implement release_region_range
