Then we may want to do this too for the boards that don't have any UART.

Subject: [PATCH] omap: Fix uncompress code for boards with no UART
With the recent DEBUG_LL and uncompress code changes, boards
with no UART configured fail to boot as pointed out by
Cory Maccarrone <darkstar6262@xxxxxxxxx>.
Some boards may not have UARTs available at all, so add
DEBUG_LL_NONE option for that.
