The U_BOOT_DRIVER macro creates a list of drivers used at link time, and
all entries here must be unique. This in turn means that all entries in
the code should also be unique in order to not lead to build failures
later with unexpected build combinations. Typically, the problem we have
here is when a driver is obviously based on another driver and didn't
update this particular field and so while the name field reflects
something unique the linker entry itself is not. In a few places this
provides a more suitable string name as well, however.

As exposed by "make randconfig", we have an issue with the dependencies
for REGMAP (and xPL variants). As this is a library function, it should
always be selected and not depended on by other functionality. This is
largely done correctly today, so just correct the few outliers.

Add support for eMMC specification version 5.1B by defining
MMC_VERSION_5_1B and including it in the version array.

eMMC 5.1B (JESD84-B51B) is a minor revision of the 5.1 specification
that primarily addresses MDT (Manufacturing Date) adjustment for dates
beyond 2025. This aligns with the Linux kernel commit 9996707822f82
("mmc: core: Adjust MDT beyond 2025").

Since the manufacturing date field is not currently used in U-Boot,
this change has no functional impact beyond proper device recognition.
It allows the driver to correctly identify and initialize eMMC devices
that report version 5.1B in their Extended CSD register.

When using a fixed 1.8V regulator for vqmmc (indicated by vs18_enable),
attempting to change the voltage produces spurious errors since the
regulator cannot be adjusted. The driver currently attempts the voltage
change, receives -ENOSYS from the regulator subsystem, and reports:

  Setting to 1.8V error: -38
  esdhc_set_voltage error -5

Fix this by checking vs18_enable early in esdhc_set_voltage() and
returning -ENOTSUPP for all voltage switch requests, not just 3.3V.
This prevents unnecessary regulator operations and eliminates the
error messages when the hardware is correctly configured with a fixed
1.8V supply.

Add support for MediaTek MT8189 MMC controller.

According to [1], this is similar to, but not quite the same as
mediatek,mt8196-mmc.

Peng Fan (OSS) <peng.fan@oss.nxp.com> says:

This patch set primarily removes unused DECLARE_GLOBAL_DATA_PTR
instances.

Many files declare DECLARE_GLOBAL_DATA_PTR and include
asm/global_data.h even though gd is never used. In these cases,
asm/global_data.h is effectively treated as a proxy header, which is
not a good practice.

Following the Include What You Use principle, files should include
only the headers they actually depend on, rather than relying on
global_data.h indirectly. This approach is also adopted in Linux kernel
[1].

The first few patches are prepartion to avoid building break after
remove the including of global_data.h.

A script is for filtering the files:
list=`find . -name "*.[ch]"`
for source in ${list}
do
        result=`sed -n '/DECLARE_GLOBAL_DATA_PTR/p' ${source}`
        if [ "${result}" == "DECLARE_GLOBAL_DATA_PTR;" ]; then
                echo "Found in ${source}"

                result=`sed -n '/\<gd\>/p' ${source}`
                result2=`sed -n '/\<gd_/p' ${source}`
                result3=`sed -n '/\<gd->/p' ${source}`
                if [ "${result}" == "" ] && [ "${result2}" == "" ] && [ "${result3}" == "" ];then
                        echo "Cleanup ${source}"
                        sed -i '/DECLARE_GLOBAL_DATA_PTR/{N;/\n[[:space:]]*$/d;s/.*\n//;}' ${source}
                        sed -i '/DECLARE_GLOBAL_DATA_PTR/d' ${source}
                        sed -i '/global_data.h/d' ${source}
                        git add ${source}
                fi
        fi

Remove DECLARE_GLOBAL_DATA_PTR from files where gd is not used, and
drop the unnecessary inclusion of asm/global_data.h.

Headers should be included directly by the files that need them,
rather than indirectly via global_data.h.
