Yes, I am booting in internal mode, so that I can load U-Boot from NAND
(or SPI flash).

I essentially have it working on 2011.06 from NAND. However I wouldn't
guarantee that the code is necessarily suitable for the main tree. I
have done it via the #include method previously mentioned.

Just out of interest, how does the imximage.cfg file work? I can't see
any reference to that file in any of the build system, so how do you get
it prepended to the image?

Andre
