I can only guess that he means that he doesn't want to have a separate
tool for generating images but instead wants to generate the images
using C structures in the original binary like we do on i.MX currently.
Anyway, what we do on i.MX doesn't really scale anymore since the more
complicated features of the image format can't be used with C
structures. I'm working on replacing this with a imx-image tool.
You seem to use checksums in your images. These can't be generated
in C or CPP anyway.
