That should be fixed by that.

That is what I told you: you should validate earlyprintk, starting by
validating printascii alone, that is, compile a kernel with
CONFIG_DEBUG_LL, without CONFIG_EARLY_PRINTK, and add a call to
printascii somewhere in the boot process, not in vprintk implementation.
earlyprintk is a module parameter with no argument: what uart is used by
printascii is determined, as I also told you, by the code in
arch/arm/plat-omap/include/plat/uncompress.h, it is not a dynamic parameter.
