I plan to commit this with the following minor addition:

diff --git a/include/configs/am335x_evm.h b/include/configs/am335x_evm.h
index e915f56..36f9152 100644

"console=ttyO0,115200n8\0" \

This still leaves a ton of room between the kernel load and
ramdisk/device tree, and sets aside as much room as the PowerPC boards
have been.
