2018-01-12mmc: Retry some MMC cmds on failureKishon Vijay Abraham I
With certain SD cards like Kingston 8GB/16GB UHS card, it is seen that MMC_CMD_ALL_SEND_CID cmd fails on first attempt, but succeeds subsequently. Therefore, retry MMC_CMD_ALL_SEND_CID cmd a few time as done in Linux kernel. Similarly, it is seen that MMC_CMD_SET_BLOCKLEN may fail on first attempt, therefore retry this cmd a few times as done in kernel. To make it clear that those are optionnal workarounds, a new Kconfig option 'MMC_QUIRKS' is added (enabled by default).

2017-08-01dm: mmc: Allow disabling driver model in SPLSimon Glass
At present if U-Boot proper uses driver model for MMC, then SPL has to also. While this is desirable, it places a significant barrier to moving to driver model in some cases. For example, with a space-constrained SPL it may be necessary to enable CONFIG_SPL_OF_PLATDATA which involves adjusting some drivers. Add new SPL versions of the options for DM_MMC, DM_MMC_OPS and BLK. By default these follow their non-SPL versions, but this can be changed by boards which need it.
