Change the mmc displayed name in U-Boot for stm32_sdmmc2 driver to

This stm32_sdmmc2 driver is for version 2 of the ST HW IP SDMMC but the
displayed name "STM32 SDMMC2" is confusing for user, between the
instance of SDMMC and the device identifier of MMC.
For example on EV1 board, we have:

STM32 SDMMC2: 1 (eMMC)
Changed to more clear:

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.

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.

According to the HW team, for some reason the normal clock select code
picks what appears to be a perfectly valid 375KHz SD card clock, based
on the CAR clock source and SDMMC1 controller register settings (CAR =
408MHz PLLP0 divided by 68 for 6MHz, then a SD Clock Control register
divisor of 16 = 375KHz). But the resulting SD card clock, as measured by
the HW team, is 700KHz, which is out-of-spec. So the WAR is to use the
values given in the TRM PLLP table to generate a 400KHz SD-clock (CAR
clock of 24.7MHz, SD Clock Control divisor of 62) only for SDMMC1 on
T210 when the requested clock is <= 400KHz. Note that as far as I can
tell, the other requests for clocks in the Tegra MMC driver result in
valid SD clocks.

This driver currently performs cache operation before the DMA start,
but does nothing after the DMA completion.
When reading data by DMA, the cache invalidation is needed also after
finishing the DMA transfer. Otherwise, the CPU might read data from
the cache instead of from the main memory when speculative memory read
or memory prefetch occurs.
Instead of calling the cache operation directly, this commit adds
dma_unmap_single(), which performs cache invalidation internally,
but drivers do not need which operation is being run.
Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>
Currently, sdhci_prepare_dma() calls flush_cache() regardless of the

behind the scene.

The reference manuals for MPC8308 and MPC8309 both say that the
esdhcctl aka DMA Control Register "is implemented as SDHCCR" in the
System configuration registers. Unfortunately, that doesn't mean that
the registers are just mirrors of each other - any write to esdhcctl
is simply ignored. So to actually enable cache snooping, we
unfortunately have to add a little ifdeffery.
There is, naturally, no description of the bit fields of esdhcctl in
the MPC8309 manual, but comparing the description of esdhcctl from the
LS1021A reference manual to the description of the sdhccr in MPC8309,
one also finds that the fields are bit-reversed, so the bit to set is
0x02000000 rather than 0x00000040 - this is also what board_mmc_init()

Cadence sent out an errata report to their customers of this IP.
This errata is not so severe, but the tune request should be sent
twice to avoid the potential issue.
Quote from the report:
Problem Summary
---------------
The IP6116 SD/eMMC PHY design has a timing issue on receive data path.
This issue may lead to an incorrect values of read/write pointers of
the synchronization FIFO. Such a situation can happen at the SDR104
and HS200 tuning procedure when the PHY is requested to change a phase
of sampling clock when moving to the next tuning iteration.
Workarounds
-----------
The following are valid workarounds to resolve the issue:
1. In eMMC mode, software sends tune request twice instead of once at
each iteration. This means that the clock phase is not changed on
the second request so there is no potential for clock instability.
2. In SD mode, software must not use the hardware tuning and instead
perform an almost identical procedure to eMMC, using the HRS34 Tune
Force register.

Bartosz Golaszewski agrees that with the impending release we should
revert the change for now. With that noted:

At present if CONFIG_SPL_GPIO_SUPPORT is enabled then the GPIO uclass
is included in SPL/TPL without any control for boards. Some boards may
want to disable this to reduce code size where GPIOs are not needed in
SPL or TPL.
Add a new Kconfig option to permit this. Default it to 'y' so that
existing boards work correctly.
Change existing uses of CONFIG_DM_GPIO to CONFIG_IS_ENABLED(DM_GPIO) to
preserve the current behaviour. Also update the 74x164 GPIO driver since
it cannot build with SPL.
This allows us to remove the hacks in config_uncmd_spl.h and
Makefile.uncmd_spl (eventually those files should be removed).

The MMC boot is currently broken on omapl138-lcdk after enabling the
driver model in SPL. The main problem is the driver's bind callback not
being called after probe in SPL (even with the DM_FLAG_PRE_RELOC flag
specified).
While a proper fix is still being worked on, this hacky changeset at
least fixes the MMC boot on this platform by calling mmc_bind()
manually from probe().

This patch is to get clock directly from global data.
- Remove uclass clk api method. This was what i.MX platforms were
using, while QorIQ platforms weren't.
- Get clock only from global data, dropping mxc_get_clock().
QorIQ eSDHC controllers on one silicon use same reference clock.

Rockchips dwmmc controllers can't do dma to non-ddr addresses,
like for example the soc-internal sram but during boot parts of
TrustedFirmware need to be placed there from the read FIT image.
So add handling for a u-boot,spl-fifo-mode to not put the mmc
controllers into fifo mode for all time.
The regular fifo-mode property still takes precedent and only
if not set do we check for the spl-specific property.

During mmc initialization, there are several calls to mmc_set_clock
and mmc_set_ios. When mmc_power_off, the mmc->clock will be set,
but the imx driver will use 400KHz. So the following calls
to mmc_set_ios will set the clock several times which is redundant
in fsl_esdhc_imx driver. So let's simplify to remove redundant
clock settings.

This patch is to clean up bus width setting code.
- For DM_MMC, remove getting "bus-width" from device tree.
This has been done in mmc_of_parse().
- For non-DM_MMC, move bus width configuration from fsl_esdhc_init()
to fsl_esdhc_initialize() which is non-DM_MMC specific.
And fix up bus width configuration to support only 1-bit, 4-bit,
or 8-bit. Keep using 8-bit if it's not set because many platforms
use driver without providing max bus width.
- Remove bus_width member from fsl_esdhc_priv structure.
