Dear Tom,
This pull request introduces initial U-Boot support for Agilex7 M-series, along with several enhancements and cleanups across existing Agilex platforms. Key changes include new board support, DDR driver additions, updated device trees, and broader SoCFPGA SPL improvements.
Highlights:
* Agilex7 M-series bring-up:
* Basic DT support and board initialization for Agilex7 M-series SoC and SoCDK.
* New sdram_agilex7m DDR driver with UIBSSM mailbox support and HBM support.
* Clock driver support for Agilex7 M-series.
* New defconfig: socfpga_agilex7m_defconfig.
* Agilex and Agilex5 enhancements:
* Improved SPL support: ASYNC interrupt enabling, system manager init refactor, and cold scratch register usage.
* Updated firewall probing and watchdog support in SPL.
* Cleaned up DDR code, added secure region support for ATF, and improved warm reset handling.
* Device Tree and config updates:
* Migration to upstream Linux DT layout for Agilex platforms.
* Consolidated socfpga_agilex_defconfig and removed deprecated configs.
* Platform-specific environment variables for Distro Boot added.
* Driver fixes and cleanups:
* dwc_eth_xgmac and clk-agilex cleanup and improvements.
* Several coverity and style fixes.
Contributions in this PR are from Alif Zakuan Yuslaimi, Tingting Meng, and Andrew Goodbody.
This patch set has been tested on Agilex 5 devkit, Agilex devkit and Agilex7m devkit.

Thanks.
Best regards,
