2020-04-22mmc: tmio: sdhi: Implement get_b_max functionMarek Vasut
Implement get_b_max() for the Renesas R-Car SDHI controller driver, limit the b_max per hardware capabilities such that select Gen2 controllers have 16bit block transfer limit, the rest has 32bit block transfer limit and on Gen3, the block transfer limit on addresses above the 32bit boundary is set to 1/4 of the malloc area. Originally, on Gen3, the block transfers above the 32bit area were limited to PIO only, which resulted in (R8A7795 Salvator-X , HS200 eMMC): => time mmc read 0x0000000700000000 0 0x10000 time: 0.151 seconds => time mmc read 0x0000000700000000 0 0x100000 time: 11.090 seconds with bounce buffer in place and b_max adjustment in place: => time mmc read 0x0000000700000000 0 0x10000 time: 0.156 seconds => time mmc read 0x0000000700000000 0 0x100000 time: 2.349 seconds Note that the bounce buffer does mallocate and free the bounce buffer for every transfer. Experiment which removes this results in further increase of read speed, from 2.349s to 2.156s per 512 MiB of data, which is not such a significant improvement anymore. It might however be interesting to have bounce buffer directly in the MMC core or even block core.

2020-04-22mmc: Add option to adjust b_max before long readMarek Vasut
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.

2020-04-22mmc: tmio: sdhi: Use bounce buffer to avoid DMA limitationsMarek Vasut
The R-Car SDHI DMA controller has various restrictions. To work around those restrictions without falling back to PIO, implement bounce buffer with custom alignment check function which tests for those limitations.

Register value table for DDR PHY clock divider are wrong. They should be 0 or 1 for divide-by-2 or divide-by-4, respectively. Not 1 or 2. Current values do not make sense, since 2 cannot be achieved, because the register is only 1 bit long (mask is set to 1). This fixes clk dump reporting DDR PHY clock rate differently from Linux.
