12ea13ad43 mmc: socfpga: Add clock framework support
Add support for fetching the clock frequency both using the legacy
method in case clock framework is disabled as well as via the clock
framework if it is enabled. This allows for migration to the clock
framework on platforms which supports it while not breaking legacy
platforms. That said, the legacy method must be removed eventually.

7c350a2a0f ARM: Odroid XU3: Fix the dwmci_exynos *priv data assignment for DM_MMC (sdr_timing)
By convention for DM_MMC the host->priv is used to store struct udevice
*dev pointer.

Unfortunately, the legacy Exynos DW MMC code uses this field to
store pointer to dwmci_exynos_priv_data struct
Hence, we do need to get data in other way - namely by using container_of
when host pointer is present.
In this way the sdr_timing data is properly accessed.

This commit prevents memory leak when this function is used with DM_MMC

79fd08f745 mmc: Unirqify bcm2835_sdhost and fix writes
The bcm2835 sdhost driver has a problem with "write multiple" commands.
It seems to boil down to the fact that the controller dislikes its FIFO
to get drained at the end of a block when a write multiple blocks command
is in flight.

The easy fix is to simply get rid of all the IRQ driven logic and make
the driver push as much data into the FIFO as it can. That way we never
drain and we never run into the problem.

360 bytes. Furthermore, since MMC tiny supports only one controller
at all times, get rid of mallocating the ext csd backup and replace
it with static array. All in all, this patch saves ~4 kiB of bloat
from the MMC core, which on platforms with severe limitations can be
beneficial.

83d290c56f SPDX: Convert all of our single license tags to Linux Kernel style
When U-Boot started using SPDX tags we were among the early adopters and
there weren't a lot of other examples to borrow from.  So we picked the
area of the file that usually had a full license text and replaced it
with an appropriate SPDX-License-Identifier: entry.  Since then, the
Linux Kernel has adopted SPDX tags and they place it as the very first
line in a file (except where shebangs are used, then it's second line)
and with slightly different comment styles than us.

In part due to community overlap, in part due to better tag visibility
and in part for other minor reasons, switch over to that style.

This commit changes all instances where we have a single declared
license in the tag as both the before and after are identical in tag
contents.  There's also a few places where I found we did not have a tag
and have introduced one.

88a57125fa mmc: sdhci: add SDHCI_QUIRK_BROKEN_HISPD_MODE
Some IP-core implementations of the SDHCI have different troubles on the
silicon where they are placed.

On ZYNQ platform for example Xilinx doesn't accept the hold timing of an
eMMC chip which operates in High-Speed mode and must be forced to
operate in non high-speed mode. To get rid of this
"SDHCI_QUIRK_BROKEN_HISPD_MODE" is introduced.

For more details about this refer to the Xilinx answer-recor #59999
https://www.xilinx.com/support/answers/59999.html

This commit:
- doesn't set HISPD bit on the host-conroller
- reflects this fact within the host-controller capabilities

Upon this the layer above (mmc-driver) can setup the card correctly.

Otherwise the MMC card will be switched into high-speed mode and causes
possible timing violation on the host-controller side.

d024236e5a Remove unnecessary instances of DECLARE_GLOBAL_DATA_PTR
We have a large number of places where while we historically referenced
gd in the code we no longer do, as well as cases where the code added
that line "just in case" during development and never dropped it.

5ff8e54888 sunxi: improve throughput in the sunxi_mmc driver
Throughput tests have shown the sunxi_mmc driver to take over 10s to
read 10MB from a fast eMMC device due to excessive delays in polling
loops.

This commit restructures the main polling loops to use get_timer(...)
to determine whether a (millisecond) timeout has expired.  We choose
not to use the wait_bit function, as we don't need interruptability
with ctrl-c and have at least one case where two bits (one for an
error condition and another one for completion) need to be read and
using wait_bit would have not added to the clarity.

The observed speedup in testing on a A31 is greater than 10x (e.g. a
10MB write decreases from 9.302s to 0.884s).
