[Qemu-devel] [PULL 04/23] imx: Use memory_region_init_rom() for ROMs

[Peter Maydell]

The imx boards were all incorrectly creating ROMs using
memory_region_init_rom_device() with a NULL ops pointer. This
will cause QEMU to abort if the guest tries to write to the
ROM. Switch to the new memory_region_init_rom() instead.
