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.
I am not defining and publishing a format for the external world. It's just an internal information much like any other info embedded in start.S such as _bss_end_ofs, _end_ofs etc. It's just that SPL, being an insider, can take advantage of it.
I feel creating a new mkimage target just for this will be an overkill. I will be happy loading the maximum image size always.
best regards, Aneesh
