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.

net: dwc_eth_xgmac_socfpga: Remove always true test

2025-08-08T07:59:58Z

In dwxgmac_of_get_mac_mode there is a test for mac_mode which will return if false. After this point mac_mode is guaranteed to be true so there is no need to test for this. Remove that test. This issue was found by Smatch. Signed-off-by: Andrew Goodbody Reviewed-by: Tien Fong Chee

net: dwc_eth_xgmac: Use unwind goto on error

2025-08-08T07:58:10Z

In xgmac_probe there is a direct return after the point where unwind gotos start to be used to undo actions performed by earlier code. Use the appropriate unwind goto instead. This issue was found by Smatch. Signed-off-by: Andrew Goodbody Reviewed-by: Tien Fong Chee

net: fec_mxc: Set error code on error exit

2025-08-07T11:16:18Z

In fecmxc_probe if a timeout is detected when resetting the chip no error code is set before taking the error exit. This could lead to a silent failure. Instead set an error code. This issue was found by Smatch. Signed-off-by: Andrew Goodbody

net: rswitch: Fix error detection

2025-08-06T14:52:27Z

In rswitch_probe the error detection after the call to devm_clk_get is very wrong. It checks the value of ret which is uninitialised at that point. Instead it should be using the macros for including errors into pointers. This issue was found by Smatch. Signed-off-by: Andrew Goodbody Reviewed-by: Marek Vasut

net: phy: Support overriding Auto Negotiation timeout with env variable

2025-08-01T08:42:22Z

The Auto Negotiation procedure between two Ethernet PHYs consists of determining the best commonly supported parameters among Speed, Duplex Mode and Flow Control. The time taken for this procedure is not only dependent on the local PHY used, but also on the link-partner PHY. While a timeout can be specified in the form of a "CONFIG" on the basis of the local PHY present on the device, since the timeout also depends on the link-partner PHY, it might be necessary to modify the timeout. To avoid rebuilding the bootloader for a given device, just because it may be connected to various link-partner PHYs, each with a different timeout, introduce an environment variable named "phy_aneg_timeout" and override "CONFIG_PHY_ANEG_TIMEOUT" with "phy_aneg_timeout".

net: Tighten some network driver dependencies

2025-08-01T07:30:47Z

A large number of network drivers cannot build without access to some platform specific header files. Express those requirements in Kconfig as well. This covers the QUICC engine drivers as that is networking driver infrastructure. Signed-off-by: Tom Rini

drivers/net/ftgmac100.c: Fix a debug print

In the debug print in ftgmac100_send we want to say where the packet is in memory and what the length is, so use %p to print that. Signed-off-by: Tom Rini
