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.
