* TODO(crosbug.com/p/23805): Technically we can write in word-mode (4 bytes at
* a time), but that's really slow, and older host interfaces which can't ask
* about the ideal size would then end up writing in that mode instead of the
* faster page mode. So lie about the write size for now. Once all software
* (flashrom, u-boot, ectool) which cares has been updated to know about ver.1
* of EC_CMD_GET_FLASH_INFO, we can remove this workaround.
