Hey Luiz,
I just tried your patches with a a fresh -HEAD.
The mmc driver seems to register just fine and is able to detect the =
partitions on my sd card.=20
However my Cubieboard doesn=E2=80=99t seem to get to the login prompt, =
it gets stuck after the =E2=80=9Cwarning: no time-of-day clock =
registered=E2=80=A6=E2=80=9D
After this happened I waited a while just to make sure it wasn=E2=80=99t =
slow read speeds, CPU die gets really warm.=20
Also the system didn=E2=80=99t freeze, when I plug in a USB stick it =
still outputs messages to the console.
Any ideas about what could be going on?
