misc: ele_api: Add support for XSPI SET GMID command

2026-03-16T21:44:58Z

The XSPI SET GMID command is used to assign GMID ownership to the requester, allowing access to protected XSPI control registers. This API must be called in SPL if XSPI GMID-protected settings need to be modified. Otherwise, XSPI configuration depends on the previous GMID owner to provide the correct settings.

imx9: scmi: Get DDR size through SM SCMI API

2026-03-16T21:44:00Z

System Manager(SM) has implemented the MISC protocol to retrieve DDR information. Using this API, U-Boot can obtain the DDR size dynamically instead of relying on static configuration macros. This change addresses the DDR ECC enabled case, where 1/8 of the total DDR size is reserved for ECC data. The scmi_misc_ddrinfo() returns the DDR size with EEC overhead already deducted. Implementation details: - Query the DDR size via scmi_misc_ddrinfo() - Replace direct REG_DDR_CS[0,1]_BNDS register reads with SCMI call - Switch from PHYS_SDRAM[x]_SIZE macros to runtime detection - For backward compatibility with older SM firmware, fall back to static PHYS_SDRAM[x]_SIZE configuration if the SCMI call fails Signed-off-by: Ye Li Signed-off-by: Alice Guo Reviewed-by: Peng Fan

imx9: Add i.MX94 CPU type and SoC-level Kconfig

2025-09-26T12:51:21Z

Introduce support for the new i.MX94 processor, including its CPU type and SoC-level Kconfig entry. The i.MX94 is a new member of the i.MX9 family. It uses a System Manager to handle system-level functions such as power, clock, sensor and pin control. The System Manager runs on a Cortex-M processor, while the Cortex-A processor communicates with it via the ARM SCMI protocol and a messaging unit.

imx: hab: Make imx_hab_is_enabled dependent on FIELD_RETURN

2024-11-09T11:53:36Z

The decision on whether HAB is enabled is solely based on the SEC_CONFIG fuse. The HAB FIELD_RETURN feature is able to permanently disable HAB on a CPU, after which it is able to boot unsigned firmware. U-Boot however does not take into account the FIELD_RETURN mode, and refuses to boot unsigned software when the feature is enabled. Also take the FIELD_RETURN fuse into account when deciding whether HAB is enabled. When The FIELD_RETURN fuse is blown, HAB is not enabled. Tested on i.MX8M Mini, i.MX8M Plus, i.MX8M Nano and i.MX6ULL Signed-off-by: Paul Geurts
