If paging is not supported, then we will attempt to apply dynamic relocations to fix up the runtime addresses. If the image is currently executing directly from flash memory, this can result in effectively sending an undefined sequence of commands to the flash device, which can cause unwanted side effects. Perform an explicit writability test before applying relocations, using a write value chosen to be safe for at least any devices conforming to the JEDEC Common Flash Interface (CFI01).
