When I do :
barebox:/ echo "this is \"quoted text\""

I get :
barebox:/ this is \"quoted text\"

I would have expected this :
barebox:/ this is "quoted text"

It looks like the escape character is not working as expected.
When I have this in my boot script :
bootargs="$bootargs mtdparts=\"physmap-flash.0:$nor_parts;mxc_nand:$nand_parts\""

Will this work correctly ? Will the mtdparts be passed correctly to the kernel ? (I guess the escape character will remain, so I think it might be an problem, no?)
