We are moving towards distro boot that's why if this can't be done via distro boot then it should be extended. sd/mmc boot mode is handled there properly that's why I have strong doubts that this is really necessary.
Are there any good distro boot examples or write ups? Basically, I am trying to make it easy for people to work with the minized. Well at least easy for me :)
Take a look at this. https://github.com/Xilinx/u-boot-xlnx/tree/master/board/xilinx/bootscripts There are also other bootscripts for other boards.
