mmc: Define timing macro's

2020-10-27T07:13:33Z

Define timing macro's for all the available speeds of mmc. This is done similar to linux. Replace speed macro's used with these new timing macro's wherever applicable. Signed-off-by: Ashok Reddy Soma Signed-off-by: Michal Simek Reviewed-by: Peng Fan

mmc: add a mmc_hs400_prepare_ddr() interface

2020-10-12T07:46:34Z

Add a mmc_hs400_prepare_ddr() interface for controllers which needs preparation before switching to DDR mode for HS400 mode. Signed-off-by: Yangbo Lu

mmc: add a hs400_tuning flag

2020-10-12T07:46:32Z

Some controllers may have difference between HS200 tuning and HS400 tuning, such as different registers setting, different procedure, or different errata. This patch is to add a hs400_tuning flag to identify the tuning for HS400 mode. Signed-off-by: Yangbo Lu

dm: mmc: Update mmc_get_mmc_dev() to use const *

mmc: Add option to adjust b_max before long read

2020-04-22T12:41:56Z

Add getter function which permits adjusting the maximum number of blocks that could be read in a single sustained read transfer based on the location of the source/target buffer and length, before such transfer starts. This is mainly useful on systems which have various DMA restrictions for different memory locations, e.g. DMA limited to 32bit addresses, and where a bounce buffer is used to work around such restrictions. Since the U-Boot bounce buffer is mallocated, it's size is limited by the malloc area size, and the read transfer to such a buffer must also be limited. However, as not all areas are limited equally, the b_max should be adjusted accordinly as needed to avoid degrading performance unnecessarily.
