Hi Ivan, my version is attached. I've not used it for NAND so far, but changed it to use the CFI flash driver. If you rely on any custom flash driver for NOR flash be sure to keep this.
Warning: the current config file is set up for UART boot to ram. You need to change this before burning it to flash.
