From db3667413d99b8ec1b1e7e9b34c20a8883ec413d Mon Sep 17 00:00:00 2001 From: Anton Leontiev Date: Tue, 3 Sep 2019 10:52:24 +0300 Subject: [PATCH] cmd: pxe: Use internal FDT if retrieving from FDTDIR fails As FDTDIR label doesn't specify exact file to be loaded, it should not fail if no file exists in the directory. In this case try to boot with internal FDT if it exists.
