For this reason, the FMC flash device contents are remapped by HW on the first 256MB of the address space. In QEMU, this is currently done in the machine init with the setup of a region alias. Move this code to the SoC and introduce an extra container to prepare ground for the boot ROM region which will overlap the FMC flash remapping.
