Restore fulldump .img generated by flashrom

Hi, is it possible to recover full NOR image backed up with Flashrom utility via OpenWRT live image running from RAM?

I have Mikrotik device with running OpenWRT from RAM and separate .img file (Flashrom NOR .bin backup). This image contains full funcitional system included uboot,kernel,rootfs,art etc (openwrt based OS). I need erase whole NOR chip with this .bin image
