From 99329be2c58d53ccf8f597bab3de85f4c572b152 Mon Sep 17 00:00:00 2001 From: Jean-Jacques Hiblot Date: Tue, 22 Oct 2019 16:39:12 +0200 Subject: [PATCH] spl: fit: Make room in the FDT before applying overlays Make room in the FDT before applying the overlay, otherwise it may fail if the overlay is big. As the exact added size is not known in advance, just add the size of the overlay. Move after the end of the application of the overlays, the resize of the FDT for the injection of the details on the loadables.
