Message-ID: <cover.1592292685.git.zong.li@sifive.com> (raw)

This patchset include two parts, the first one is that register System
RAM as iomem resources, it is needed for page_is_ram API which checks
the specified address whether registered as System RAM in iomem_resource
list. The second patch is that add devmem_is_allowed to support
STRICT_DEVMEM, and it would invoke page_is_ram to check the addresses.
