mmc: add bcm2835 driver This adds a simple driver for the BCM2835's SD controller. Workarounds are implemented for: * Register writes can't be too close to each-other in time, or they will be lost. * Register accesses must all be 32-bit, so implement custom accessors. This code was extracted from: git://github.com/gonzoua/u-boot-pi.git master which was created by Oleksandr Tymoshenko. Portions of the code there were obviously based on the Linux kernel at: git://github.com/raspberrypi/linux.git rpi-3.6.y commit f5b930b "Main bcm2708 linux port" signed-off-by Dom Cobley. swarren changed the following for upstream: * Removed hack udelay()s in bcm2835_sdhci_raw_writel(); setting SDHCI_QUIRK_WAIT_SEND_CMD appears to solve the issues. * Remove register logging from read/write functions. * Sort out confusion with min/max_freq values passed to add_sdhci(). * Use more descriptive variable names and calculations in IO accessors. * Simplified and commented twoticks_delay calculation. * checkpatch fixes.
