Can do.

There's another issue though. The boot scripts need to be wrapped
by 'mkimage' so that U-Boot will 'source' them properly.

e.g.
	mkimage -A arm -O linux -T script -C none -a 0 -e 0 \
		-n "boot script" -d 6x_bootscript.txt 6x_bootscript


I just copied the SD card image and found that the .txt files
were copied, but not compiled.

Okay with me for now. At least this will get us up and bootable.
