Synchronize upper_NN_bits() and lower_NN_bits() macros with Linux 6.16
commit 118d777c4cb4 ("wordpart.h: Add REPEAT_BYTE_U32()"). This fixes the
lower_32_bits() macros and assures it works with 64bit systems correctly.
This also adds 16bit variants of these macros, which will be used by the

mmu_status is used in io memcpy functions to prevent accesses to non
8-byte aligned addresses when the mmu is disabled. Though there is a
redundant definition enabled when icaches is turned off by setting
SYS_ICACHE_OFF.
This patch removes the redundant definition, allowing mmu_status to
properly report the status regardless of config settings. This shouldn't
be a problem since access to non 8-byte aligned data can be done
irrespective of icache state.

When both SPI environment locations are invalid (gd->env_valid ==
ENV_INVALID), the first call to saveenv writes to the primary location and
sets the active flag. However, the logic for updating gd->env_valid
incorrectly sets it to ENV_REDUND, which does not match the actual location
written. This causes the first two writes to target the same location, and
alternation only begins after the second write.
Update the logic to alternate gd->env_valid based on whether the last write
was to the primary or redundant location, ensuring the first write sets
ENV_VALID and subsequent writes alternate as expected. This aligns
env_valid with the actual storage location and fixes the alternation
sequence from the first write.
With this change, the "Valid environment" printout correctly reflects the
active location after each save, and the alternation between primary and
redundant locations works as intended from the start.

SoCFPGA updates for v2025.10:
CI: https://source.denx.de/u-boot/custodians/u-boot-socfpga/-/pipelines/27762
This pull request brings a set of updates across SoCFPGA platforms
covering Agilex5, Agilex7, N5X, and Stratix10. The changes include:
* Agilex5 enhancements:
- USB3.1 enablement and DWC3 host driver support
- System Manager register configuration for USB3
- Watchdog timeout increase and SDMMC clock API integration
- dcache handling improvements in SMC mailbox path
- Enable SPL_SYS_DCACHE_OFF in defconfig
* Clock driver improvements:
- Introduce dt-bindings header for Agilex clocks
- Add enable/disable API and EMAC clock selection fixes
- Replace manual shifts with FIELD_GET usage
* DDR updates:
- IOSSM mailbox compatibility check
- Correct DDR calibration status handling
* Device tree changes:
- Agilex5: disable cache allocation for reads
- Stratix10: add NAND IP node
- Enable driver model watchdog
- Enable USB3.1 node for Agilex5
* Config cleanups:
- Simplify Agilex7 VAB defconfig
- Remove obsolete SYS_BOOTM_LEN from N5X VAB config
- Enable CRC32 support for SoCFPGA
- Increase USB hub debounce timeout
Overall this set improves reliability of DDR and cache flows,
adds missing USB and MMC features for Agilex5, and refines clock
and configuration handling across platforms.
This patch set has been tested on Agilex 5 devkit, and Agilex devkit.
- set reversed bit when using internal phy on GXL SoCs
- support gpio toggle command for amlogic gpio
- fix saradc
- remove unreachable in meson clk driver
- Stop premature exit from for loop in meson pwm driver
- fix JetHub D1 eth mac fallback generation
In meson_pwm_probe the for loop attempts to get the name of a clock but
the following if..else statements only perform useful work if -ENODATA
is returned from clk_get_by_name. If clk_get_by_name simply succeeds
then this results in a premature exit from the for loop and the
following code can never be reached. Make the else clause only apply for
an error return from clk_get_by_name.

The issue was a mismatch in return value conventions between functions:
- getvar_get_part_info() expects >= 0 for success
- fb_nand_lookup() returns 0 on success, 1 on failure (from
mtdparts_init and find_dev_and_part)
When partition didn't exist, fb_nand_lookup returned 1, but
fastboot_nand_get_part_info passed it directly to getvar_get_part_info,
which treated 1 >= 0 as success, causing has-slot to always return yes.
Fix by converting positive return values to -ENOENT in
fastboot_nand_get_part_info to match the expected error convention.

While it is good that the "Licenses/" directory contains the text
for all licenses that are applicable to u-boot code, it is harder
to determine at a glance what the default and/or preferred license
is. While humans can look at the Licenses/README file, this is not
machine parseable, making it tricky for license detection tools to
automatically determine/report on the overall / aggregate u-boot
license.
The project previously had a top level COPYING file containing a
short blurb, followed by the GPL license text. This was removed
back in commit eca3aeb352 when
the "Licenses/" directory was introduced. For the benefit of
automated tools, it is helpful to retain a top level COPYING
file in the repository. Rather than duplicate the license text,
however, a symlink from the Licenses/gpl-2.0.txt file should
suffice.
