+ Define the width of the AP7000 external static memory interface.
+ This is used to determine how to mangle the address and/or data
+ when doing little-endian port access.
+
+ The current code can only support a single external memory bus
+ width for all chip selects, excluding the flash (which is using
+ raw access and is thus not affected by any of this.)
