>> Based on the below
>> commit ae3c99a26c60 ("ARM: 7806/1: allow DEBUG_UNCOMPRESS for Tegra"),
>> change the .data section to .text section,
>> to enable DEBUG_UNCOMPRESS for OMAP2+ platforms
>> Tested okay using BeagleBone Black

> Sorry for the delay, I just noticed this one while looking

> I think we should first simplify things by moving things over
> to use the generic DEBUG_UART_8250 code where the addresses
> need to be specified in the .config. It's been on my list of
> things to do for quite a while but I keep getting interrupted.
>
> My guess is that if we do that, this patch is no longer
> needed :) Yong, care to take a look at that?
