mmc: tmio: sdhi: Implement get_b_max function

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.

Marek Vasut [Sat, 4 Apr 2020 10:45:05 +0000 (12:45 +0200)]
mmc: Add option to adjust b_max before long read

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.

to the relevant device-trees and augment the FEC node with properties
for the reset GPIO.

It should be noted that the relevant properties for the reset GPIO
already exist in the PHY node (reset-gpios, reset-delay-us,
reset-post-delay-us) but U-Boot currently ignores those and only

do not have the PMIC nodes.

This causes revD1 boards to be incorrectly be detected as revB1.
