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
done

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.

In theory, for the same vendor, we should use the same instructions as
the spi-nor-core implementation.

These chips are internally made of two/four dies with linear addressing
capabilities to make it transparent to the user that two/four dies were
used. There is one drawback however, the read status operation is racy
as the status bit only gives the active die status and not the status of
the other die. For commands affecting the two dies, it means if another
command is sent too fast after the first die has returned a valid
status (deviation can be up to 200us), the chip will get corrupted/in an
unstable state.

The solution adopted here is to iterate manually over all internal
dies (which takes about 30us per die) until all are ready. This approach
will always be faster than a blind delay which represents the maximum
deviation, while also being totally safe.

A flash-specific hook for the status register read had to be
implemented. Testing with the flash_speed benchmark in Linux shown no
difference with the existing performances (using the regular status read
core function).

As the presence of multiple dies is not filled in these chips SFDP
tables (the table containing the crucial information is optional), we
need to manually wire the hook.

This change is adapted from Linux.

Some Winbond Flash chips share the same device ID. Names are not that
important for the SPI Flash, hence we don't need these duplicate ID
definitions. And the Flash size of w25q512jv is actually wrong. Clean
them up to keep the source file tidy.

First set of u-boot-at91 features for the 2026.04 cycle:

This small fixes set includes fixing 64 bit builds and some warnings for
the at91 serial driver, and some cleanup on the nand driver.

Mikhail Kshevetskiy <mikhail.kshevetskiy@iopsys.eu> says:

It was noted that a GPT partition with the maximum available partition
number (ex: /dev/mmcblk128) can't be read/write from U-Boot using
read/write commands. Futher investigation shows that the problem is
deeper.

This set of patches fixes uncovered issues.
