a3f0a7d5b5 mmc: sh_sdhi: Fix the ACMD handling
The command handling in this driver is awful, esp. because the driver
depends on command numbers to determine whether this is APPCMD or not.
Also, handling of command RSP response types is totally wrong.

This patch at least plucks out some of the custom command encoding and
fixes the APPCMD handling. The RSP handling still needs work, yet that
might not be needed as it turns out the uniphier-sd.c driver is in much
better shape and supports the same IP, so we might be able to just drop
this driver in favor of the uniphier one.

c4d660d4d0 dm: mmc: Allow disabling driver model in SPL
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.

aae6f016a7 mmc: cadence: use fdt32_t for DT property value to fix sparse warning
DTB is encoded in big endian.  When we retrieve property values,
we need to use fdt32_to_cpu (aka be32_to_cpu) for endian conversion.
This is a bit error-prone, but sparse is useful to detect endian
mismatch.

We need to use (fdt32_t *) instead of (u32 *) for a pointer of a
property value.  Otherwise sparse warns "cast to restricted __be32".

This patch adds a parameter "vs18_enable" in fsl_esdhc_cfg

settings.

We could not use CONFIG_SYS_FSL_ESDHC_FORCE_VSELECT, it has problem
that it will apply to all USDHC controllers and it only set the 1.8V
at init phase. So if user does not select to the eMMC device,
the voltage on the I/O pins are not correct.

I'm not saying this is not correct, but I would prefer to handle

For example the rk3288 SPL size has out of memory if not enable
BACK_TO_BROM option, there are many other SoCs has less internal

542b5f8567 tegra: mmc: Set the bus width correctly
The driver currently does not reset bit 5 of the hostctl register even if
the MMC stack requests it. Then means that once a bus width of 8 is
selected it is not possible to change it back to 1. This breaks
'mmc rescan' which needs to start off with a bus width of 1.

The problem was surfaced by enabling CONFIG_DM_MMC_OPS on tegra. Without
this option the MMC stack fully reinits the driver on a 'mmc rescan'.
But with this option driver model does not re-probe a driver once it has
been probed once.

Fix the driver to honour the request.
