Newer Apple firmwares on chipsets without a hardware RNG require the host to provide a buffer of 256 random bytes to the device on initialization. This buffer is present immediately before NVRAM, suffixed by a footer containing a magic number and the buffer length. This won't affect chips/firmwares that do not use this feature, so do it unconditionally.
Not sure what the general opinion is here, but pulling random bytes for naught seems wasteful to me. So if there is a way of knowing it is needed please make it conditional.
