Yes.

AFAIK the downside is that High Capacity cards will not work without it.

Looking at the code if this bit is set, then for some commands
drivers/mmc/mmc.c or-s in OCR_HCS into the mmc cmdarg, so I guess you're
right that this may cause some undesirable side effects, so lets delay
this one.

Normally I would not include new boards at this moment in the cycle, but
since we need to do a pull-req for the gmac anyways I thought it would
be nice to have it included, esp. since many distros only spin things
like sdcard boot images once, so if we do not include it now, many distros
will not get it for a significant amount of time.

Either way let me know how you want to proceed, if you think we should not
include this, then I'll send a pull-req with only the gmac fix.

I was hoping for Stephen to get around to testing it today, and then I wanted
to send it out with his Tested-by. I'll just go and send it as is for now.
