Hello, In the bootlog you pasted, I see no flash map being enabled for your device. You might want to have a look at the AMD alchemy flash driver which should provide you a basic mapping. This driver is located in linux/drivers/mtd/maps/alchemy-flash.c and can be enabled within Kconfig in the Device Driver / Memory Technology Device / Mapping drivers for chip access.
