2012-04-16DMA: Split the APBH DMA init into block and channel initMarek Vasut
This fixes the issue where mxs_dma_init() was called either twice or never, without introducing any new init hooks. The idea is to allow each and every device using the APBH DMA block to configure and request only the channels it uses, instead of making it call init for all the channels as is now. The common DMA block init part, which only configures the block, is then called from CPUs arch_cpu_init() call.

2012-04-16i.MX28: Allow coexistence of PIO and DMA mode for SD/MMCMarek Vasut
This SD DMA function of i.MX28 is still apparently too experimental to be enabled by default in 2012.04 release. Enable this feature only if the user plans to tinker with DCache or explicitly enables it.

2012-01-08mmc: Implement card detection.Thierry Reding
Check for card detect each time an MMC/SD device is initialized. If card detection is not implemented, this code behaves as before and continues assuming a card is present. If no card is detected, has_init is reset for the MMC/SD device (to force initialization next time) and an error is returned.
