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

Arg, inverted logic ;) I meant 'disable/remove' CONFIG_SYS_DCACHE_OFF
here. I.e. is it save to _enable_ the dcache now?

Try it, it might work.

You very likely do need it, yes.
