Sync the kernel devicetree source files for the Allwinner SoCs with
32-bit cores that do not use OF_UPSTREAM yet. The files were taken
from a v6.18-rc1 tree.
To maintain ABI compatibility with existing LTS kernels, one change
moving some IP blocks to the r_intc interrupt controller is excluded.
This effectively reverts Linux commits 994e5818392c and 9fdef3c3d8c2.
This commit also adds a new board devicetree for the A33 Vstar board,
plus one DT overlay for the OrangePi Zero interface board.
This update should not impact any existing U-Boot functionality.

Sync the devicetree files from the official Linux kernel tree, v6.18-rc1.
This is covering Allwinner SoCs with 64-bit ARM cores.
The bulk is cosmetic changes: board model name changes, DT node renames,
whitespace fixes.
The actual changes are not dramatic: the CPU cores get their caches
described properly, some A64 video clocks get fixed, some A64 boards
describe the header pins for the WiFi module, the Pinephone adds an
alternative magnetometer used on some board revisions.
On the H5 side the microSD slots get marked as having no write-protect
detection, and the NanoPi Neo Plus2 board describes its regulators better.
The H6 boards switch from RSB to I2C for their PMIC connection.
As before, this omits the non-backwards compatible changes to the R_INTC
controller, to remain compatible with older kernels.

In contrast to some other Allwinner SoCs, there is no difference between
the DTs for the Allwinner A80 SoCs (sun9i) between the U-Boot and the
Linux kernel repository.
Remove the old copies of the A80 related .dts and .dtsi files, and switch
most of sun9i boards over to use OF_UPSTREAM.
There is the Sunchip CX-A99 (family of) board(s) for which we don't have
a DT in the kernel tree. Keep the .dts file in the legacy U-Boot DT
directory, and let the board's defconfig opt out of OF_UPSTREAM.

- 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.
All SoCFPGA platforms are switching to CONFIG_WDT (driver
model for watchdog timer drivers) from CONFIG_HW_WATCHDOG. Status
of watchdog is enabled to assist with this switching.

Aristo Chen <jj251510319013@gmail.com> says:
This patch series enhances FIT image robustness by adding **memory
region overlap detection** to `mkimage` and fixing existing overlaps
in DTS files and `binman` tests.
The primary goal is to prevent runtime memory corruption from
conflicting load addresses in FIT images.
Key Changes:
1. `mkimage` Overlap Detection: A new validation in
`tools/fit_image.c` checks for overlapping load addresses
within FIT configurations. `mkimage` now errors out with
detailed info on conflicts, preventing bad FIT image creation.
2. New Test Case: A Python test verifies the new detection.
It intentionally creates an overlap (kernel and FDT)
to confirm correct error handling.
3. Fixes for Existing Overlaps:
* Board DTS (k3-am6xx): Adjusted load addresses for TI
firmware stubs to prevent conflicts. This resolves
previously undetected overlaps.
* `binman` Tests: Fixed several tests. U-Boot load
addresses were shifted to avoid ATF conflicts. A new
linker script for TEE ELF sections ensures distinct
memory layouts.
4. Documentation: Added guidance for developers on how to
determine ELF load addresses using readelf, linker scripts,
and objdump when working with binman FIT images.
Impact:
This series improves FIT image reliability by catching overlaps
at build time, helping developers resolve issues before runtime
failures.

Fix memory overlaps in FIT image configurations for TI AM62x and AM64x
PHYCore and SK boards.
The overlaps occurred in two categories:
1. TI firmware stub images (tifsstub-hs, tifsstub-fs, tifsstub-gp):
These mutually exclusive firmware variants were incorrectly assigned
the same load address within FIT configurations, causing overlap
detection to fail. Adjust addresses with 64KB spacing:
- tifsstub-hs: Keep original address
- tifsstub-fs: Move to +64KB offset
- tifsstub-gp: Move to +128KB offset
2. Device tree overlay images (som-no-rtc, som-no-spi, som-no-eth):
These overlay files had insufficient spacing between load addresses,
causing actual memory overlaps. Increase spacing to 8KB boundaries
to accommodate overlay sizes safely.
An upcoming commit will validate if the memory region is overlapped
