The constraints on the MMC_SUPPORTS_TUNING symbol can easily be
expressed in Kconfig (with the addition of SPL_MMC_SUPPORTS_TUNING).
Furthermore, in order to remove <common.h> from the MMC subsystem, the
way this symbol is used today needs to be changed in order to continue
functioning.

This follows the example of RISC-V where <asm/global_data.h> includes
<asm/u-boot.h> directly as "gd" includes a reference to bd_info already
and so the first must include the second anyhow. We then remove
<asm/u-boot.h> from all of the places which include references to "gd"
an so have <asm/global_data.h> already.

Judith Mendez <jm@ti.com> says:
The following patch series includes a MMC tuning algorithm
fix according to the following published paper [0].
This seris also includes fixes for OTAP/ITAP delay values
in j721e_4bit_sdhci_set_ios_post and for HS400 mode.
For DDR52 mode, also set ENDLL=1 and call am654_sdhci_setup_dll()
instead of am654_sdhci_setup_delay_chain() according to
device datasheet[1].

At HS400 mode the ITAPDLY value is that from High Speed mode
which is incorrect and may cause boot failures.
The ITAPDLY for HS400 speed mode should be the same as ITAPDLY
as HS200 timing after tuning is executed. Add the functionality
to save ITAPDLY from HS200 tuning and save as HS400 ITAPDLY.

Currently the sdhci_am654 driver only supports one tuning
algorithm which should be used only when DLL is enabled. The
ITAPDLY is selected from the largest passing window and the
buffer is viewed as a circular buffer.
The new tuning algorithm should be used when the delay chain
is enabled; the ITAPDLY is selected from the largest passing
window and the buffer is not viewed as a circular buffer.
This implementation is based off of the following paper: [1].
Also add support for multiple failing windows.

Port the RK3328 part of the Rockchip IO-domain driver from linux.
This differs from linux version in that pmu io iodomain bit is enabled
in the write ops instead of in an init ops as in linux, this way we can
avoid keeping a full state of all supply that have been configured.
Enable by default on all RK3328 boards, skip rk3328-evb because this

The commit 2cc6cde647e2 ("mmc: rockchip_sdhci: Limit number of blocks
read in a single command") introduced a limit of number of blocks to
read to fix a Data End Bit Error on RK3568 and RK3588. This had a side
affect of significant slowing down reading FIT from eMMC.
After the commit 6de9d7b2f13c ("rockchip: rk35xx: Enable eMMC HS200 mode
by default") the limit of number of blocks to read workaround is no
longer necessary and at HS200+ a Data End Bit Error is no longer
happening using PIO mode.
Change this limitation to allow reading more than 4 blocks with a single
CMD18 command in PIO mode at HS200+ speed, keep using the 4 blocks
limitation when loadig FIT from eMMC at lower speed than HS200.

Currently fetching files bigger that cause a data transfer greater than
U16_MAX fails.
The reason is that the specification defines the datalength register
as a 16 bit wide register, but in u-boot it is used as if it is an
32 bit register. Therefore values greater than U16_MAX cause an
infinite loop inside u-boot. U-boot expects to get more data from
interface/hardware then it will ever get and therefore inifintely waits
for more data that will never come.

Some arm64 platforms may include SDIO host controllers that
only support 32-bit ADMA. While the Linux kernel detects which
size is supported and adjusts the descriptor size used dynamically,
the previous u-boot implementation statically selected between the
two depending on whether DMA_ADDR_T_64BIT was defined. Because the
static selection is already in place and effective for most platforms,
this patch logically separates "64 bit addresses are used for DMA on
this platform" and "64 bit addresses are used by the SDIO host
controller for ADMA" in order to support the small number of platforms
where these statements are not equivalent.
Using 32 bits is opt-in and existing 64 bit platforms should be
unaffected by this change.

Add this hook so that it can be overridden with driver specific
implementations. We also let the original sdhci_adma_write_desc()
accept &desc so that the function can set its new value. Then export
the function so that it could be reused by driver's specific
implementations.
The above is a port of Linux kernel commit 54552e4948cbf
In addition, allow drivers to allocate their own ADMA descriptor
tables if additional space is required.
Finally, fix the assignment of adma_addr to fix compiler warning
on 64-bit platforms that still use 32-bit DMA addressing.

Support is added for 5 new Qualcomm SoCs:
* QCM2290 and SM6115 are low and mid range SoCs used on the RB1 and RB2
respectively. SM6115 is also used in some mid-range smartphones/tablets.
Initial support includes buttons and USB (host and gadget).
* SM8250 is a flagship SoC from 2020 used on the RB5, as well as many flagship
smartphones. The board can boot to a U-Boot prompt, but is missing regulators
necessary for USB support.
* SM8550, and SM8650 are flagship mobile SoCs from 2023 and 2024
respectively. Found on many high end smartphones.
In addition:
* Support is added for the Schneider HMIBSC board.
* mach-snapdragon switches to OF_UPSTREAM
* IPQ40xx gets several regressions fixed and some overall cleanup.
* The MSM serial driver gains the ability to generate the bit-clock
automatically, no longer relying on a custom DT property.
* The Qualcomm SMMU driver gets a generic compatible (so per-SoC compatibles
don't need to be added).
* Support for the GENI I2C controller is added.
* The qcom SPMI driver has SPMI v5 support fixed, and v7 support added.
* The qcom sdhci driver gets some fixes for SDCC v5 support.
* SDM845 gains sdcard support
* Support is added for the Synopsys eUSB2 PHY driver (used on SM8550 and SM8650)
* SYS_INIT_SP_BSS_OFFSET is set to 1.5M to give us more space for FDTs.
* RB2 gets a work-around to fix the USB dr_mode property before booting Linux.
