Changes for v2
- Using load command instead of fatload
The distro_bootcmd can do this and even let's you boot debian/fedora on such a machine in a standardized way. Should we switch to distro_bootcmd instead of adding new ad-hoc stuff ?

It seems to me that we need to add script into the fs to get that work, right?

Yes, that's right. CCing Vagrant, he's the debian guru around here.

Yes and no. Currently Debian uses a bootscript generated with flash-kernel, such as:
https://anonscm.debian.org/cgit/d-i/flash-kernel.git/tree/bootscript/all/boo...
But you can also use a syslinux formatted plain text file, such as extlinux.conf or pxelinux.conf/default, described in u-boot/doc/README.distro. They look something like this:
label Boot kernel /boot/vmlinuz append ro root=/dev/sda2 console=ttyS0,115200n8 fdtdir /boot/dtbs/ initrd /boot/initrd.img
The (only) reason debian hasn't yet switched to syslinux-style config files is that is that the console settings vary wildly by board, and the "chosen" console property isn't yet consistantly supported on all boards and kernel versions in use. That may change soon.
But the distro_bootcmd support supports both syslinux-style files and bootscripts out-of-the-box. Because of the standardization, for any board you would hope to see working out of the box on Debian(and I suspect Fedora as well), supporting distro_bootcmd in u-boot upstream would be ideal.

Thanks for the pointers and this looks great. I can imagine how this cool feature easing user when come to update the boot device and boot file name without the need to update the U-Boot source.
To take this advantage socfpga, ubifs support for NOR and NAND boot need to be happened first :)
Thanks Chin Liang

I already sent you a patch how to do that.
