[U-Boot] WARNING: Caches not enabled on openrd based board

[Alex Zeffertt]

Hi U-Booters,

I get the following warning when I boot our openrd based board:

> U-Boot 2012.07 (Aug 17 2012 - 10:45:29)
> OpenRD-Base
>
> SoC:   Kirkwood 88F6281_A1
> DRAM:  128 MiB
> WARNING: Caches not enabled
> NAND:  512 MiB

I am running the latest code from git with a small number of changes
to make it work with our hardware.
(In particular we have had to rewrite board/Marvell/openrd/kwbimage.cfg.)

My question is: does the warning about caches affect only U-Boot (in
which case I don't mind) or will it also affect Linux?

TIA,

Alex
