Dear Nishanth Menon,
In message j2h782515bb1005060354tc4574d80wb4a1aa3a2b40bc89@mail.gmail.com you wrote:
your points are valid, two options as I see here: a) build configurations - nand_boot, nor_boot etc.. b) IMHO, the better solution would be to allow the same u-boot to boot from all devices (nand, nor, onenand, mmc) without needing a rebuild.
b) is clearly the better and more user-friendly solution.
but the neccessity for that is to have environment variable which can be moved around.. ...
Hm... really? Assuming that all the storage devices are always present, you can decide to use one standard location for the environment independent of where the U-Boot image gets loaded from (that may actually be considered an advantage by some).
... TI has an implementation based on an ancient u-bootwhich actually does this, it will be interesting to know if there are others who may be interested in a similar feature in mainline u-boot.
Sure - please post a patch (as RFC) so we can see what you have in mind.
Best regards,
Wolfgang Denk
