[Qemu-arm] [PATCH] hw/arm/virt: Fix non-secure flash mode

From: David Engraf
Subject: [Qemu-arm] [PATCH] hw/arm/virt: Fix non-secure flash mode
Date: Fri, 12 Jul 2019 09:50:02 +0200

Using the whole 128 MiB flash in non-secure mode is not working because
virt_flash_fdt() expects the same address for secure_sysmem and sysmem.
This is not correctly handled by caller because it forwards NULL for
secure_sysmem in non-secure flash mode.

Fixed by using sysmem when secure_sysmem is NULL.
