Hm, odd -- but I wouldn't lose sleep over it.

However, the datasheet suggests that the high byte is unspecified. Could
it be returning the value of the flash data at that location, rather
than a constant 0xFF? If so, we'd need to add a flag to the jedec match
table to make it match only the low byte?

Or maybe I'd make you do your own probe in that case, rather than
polluting jedec_probe.c... :)
