- Don't allow high-speed mode on OMAP4 due to hardware erratum. - Check the proper bit in the status register when waiting for the controller to come out of reset. - Add handling for the "non-removable" fdt property by always returning "card is present" status. - Add the non-removable property for the MMC card on a Beaglebone Black. - Add the non-removable property for Pandaboard as a workaround. For Pandaboard the card detect pin is handled by the twl6030 fpga device which gets an interrupt on pin change and then has to query the fpga for the actual status. We don't have code to do that yet.
