Dear Aneesh V,
In message 1305472900-4004-19-git-send-email-aneesh@ti.com you wrote:
Embed the u-boot flash image size at a known offset from the start of u-boot so that SPL can use it while loading u-boot from a non-XIP media.
I don't think this is a good idea.
What you are doing here is defining an image format. Such an image format must be good enough not only for OMAP4 and for loading U-Boot as second stage, but for all other architectures and use cases as well.
We therefore should be very careful not to oversimplify things here. I suggest NOT to pot this information into the image itself, but rather to prepend it (for example, using the mkimage tool), so the actual payload image needs not to be modified.
Best regards,
Wolfgang Denk
