[U-Boot] i.MX(6) dcache status?

[Dirk Behme]

Hi,

now, after U-Boot v2012.07 is released, I'd like to ask what's the 
status the dcache support for i.MX(6)? Is it safe to enable 
CONFIG_SYS_DCACHE_OFF now? E.g. for the SabreLite [1]?

And if so, do we have to enable CONFIG_MMC_BOUNCE_BUFFER, too?

Opinions?

Many thanks and best regards

Dirk
