- Subject: [PATCH 054/182] of: only scan for reserved mem when fdt present
- When the reserved memory patches hit -next, several legacy (non-DT) boot
- failures were detected and bisected down to that commit. There needs to
- be some sanity checking whether a DT is even present before parsing the
- reserved ranges.
