Hi!
maybe this helps? I just stepped into same problem on an am335x, but had not yet time to look deeper in it ...
I did not try the cleanup_before_linux(), but "dcache off" should have same effect, right?
Hmm.. not exactly... cleanup_before_linux() does also disable the mmu.
Seems like I found the reason. CONFIG_THUMB_BUILD was set, and that causes problems in put_dec_trunc() function (and elsewhere).

Disable thumb build; it breaks put_dec_trunc() function on toolchain from eldk-5.6 and eldk-5.4, and some other place, too.

Disabling thumb build to paper over the problem is certainly not a solution, right?
Well. First questions first: does it work for you? What version and what compiler?
What is the root cause for those problems and how can we fix it in the right place ?
If I knew what is the root cause, do you think I'd do this?
