Regardless of what is loading the next level (u-boot.bin) the initial flashing of NAND is still currently handled only by kobs-ng so I'm not sure how this differs in this respect. I plan to look at adding the functionality of kobs-ng to u-boot at some point.
If as I think kobs-ng is only a flasher, it does not take part to the build of U-Boot binaries. IMHO it should be not part of U-Boot sources, but maybe there are some features that can be interesting.
I was not referring to making the code a part of uboot sources but adding the functionality that it provides such that one could use uboot to update itself on an IMX NAND device. I'm actually surprised nobody has done this before for IMX in general as its a bit inconvenient to boot to a linux based OS in order to run kobs-ng to flash the bootloader. Regardless, this would be functionality added later.
That would be really convenient. Not having to boot Linux and to rely on kobs-ng for flashing U-Boot for NAND booting imx6.
It appears the only other mainlined IMX6 bootloader to support NAND is the Titanium and there is no README for it at all. If there were, I would expect it to say pretty much the same thing that my proposed Ventana README states. There was a comment by Fabio on original titanium patch to include a README explaining how to flash and boot from NAND but it apparently didn't make it in: http://thread.gmane.org/gmane.comp.boot-loaders.u-boot/158436/focus=158441
I've added Stefan Roese and Fabio to the cc to hear their thoughts.
Yes, your README seems correct to me. So for this README:
