From 53007fc1eb892cd67af97c545eb3461020cc3885 Mon Sep 17 00:00:00 2001 From: Oleksandr Andrushchenko Date: Fri, 19 Jun 2020 11:22:18 +0300 Subject: [PATCH] common/board_f: Respect original FDT size while relocating While relocating FDT we reserve some memory for the new FDT and set the size of the FDT with that respect. But FDT may be placed at the end of the RAM leading to memory access beyond it. Fix this by copying exact FDT size bytes, not the reserved size.
