Subject: [PATCH] fdt: Properly handle "no-map" field in the memory region
Date: Fri, 12 Jul 2019 10:31:24 +0200
Message-ID: <1562920284-18638-1-git-send-email-karahmed@amazon.de> (raw)

Mark the memory region with NOMAP flag instead of completely removing it
from the memory blocks. That makes the FDT handling consistent with the EFI
memory map handling.
