From 218da804ef0971ecee8063c45deae0345e344812 Mon Sep 17 00:00:00 2001 From: Patrick Delaunay Date: Thu, 25 Jan 2018 18:07:46 +0100 Subject: [PATCH] common/memsize.c: restore content of the base address For the last return of function get_ram_size(), when size=maxsize, restore the base address (*base) content. Add comment for the remaining case to avoid regression: this case is already correctly handled.
