Yes. Esp. what makes the code "big" when compared to the original
x-loader for omap3. Idea was to identify portions of code that
isn't getting used - at all (or most of the time).

I will. Just located the patches in my mailbox.

I return to OMAP3 and barebox in my free time - which isn't too
often; but I should be able to try these patches by end of this
week.

In fact, the code changes for this RFC were done in NOV - just
couldn't post because I couldn't write detailed changelong
explaining the motivation.
