There is a regression since commit c5705a7728b4a6bc9e4f2d35911adbaf28042b25 or some other recent change.
System emulation with a flash device raises an assertion in function qemu_ram_set_idstr because no new_block is found at the requested addr. The address of the memory region (mr->ram_addr) is set by memory_region_init_rom_device: mr->ram_addr = qemu_ram_alloc(size, mr); mr->ram_addr |= cpu_register_io_memory(mr); The 2nd line adds a small offset to mr->ram_addr, and this offset makes ram_set_idstr fail with an assertion. Masking mr->ram_addr with the target's page mask removes the small offset and makes flash devices work again.
