is not accessible Linux doesn't "detect" the device and doesn't create the MTD, i.e. it's not accessible from the BMC. This can be the case if the mux between BMC, PCH and BIOS SPI flash) is configured to connect the SPI flash to the BMC at the time the BMC
boots. Or is there a way to make BMC's Linux "rescan" for SPI flash chips at runtime?<o:p></o:p></span></p>
