PS2, Line 10: Convert "unknown" to "DevE"
> Why it was "unknown" before? Is Device Expansion the names from SPI guides?

Older chipsets and thus older versions of the SPI programming guide had less regions defined. Today there are 16 well known regions, even though they might not be actually used by the chipset.
