IIRC I have seen some of the controllers with memory mapped flash<br>
support where the address range for the memory mapping was optional<br>
since it could be configured out of the IP when wiring it into the<br>
platform. No idea if that's what's going on here.<br></blockquote><div><br></div><div><div><div><p dir="auto" style="white-space-collapse: preserve;">In the NPCM FIU driver:</p>
