The sdhc driver in Linux is a big piece of shit which uses the wrong
abstraction model. This is shown by the fact that 32bits are not enough
to abstract the quirks. Even with all these quirks the i.MX part of this
driver has to implement driver logic in the register access functions.
That just insane. I'm not really looking forward to add this driver
to barebox.
