Patch from Pavel Pisa This patch adds support of i.MX/MX1 SD/MMC controller. It has been significantly redesigned from the original Sascha Hauer's version to support scatter-gather DMA, to conform to latest Pierre Ossman's and Russell King's MMC-SD Linux 2.6.x infrastructure. The handling of all events has been moved to the softirq context and is designed with no busy-looping in mind. Unfortunately some controller bugs has to be overcome by limited looping about 2-20 usec but these are observed only for initial card recognition phase. There are still some missing/missed IRQs problems under heavy load. Help of somebody with access to the full SDHC design information is probably necessary. Regenerated against 2.6.16-git-060402 to solve clash with other patches.
