iMX9: scmi: Disable fused modules for iMX95/94/952

2026-06-09T16:09:27Z

Disable relevant modules in kernel FDT and u-boot FDT according to fuse settings on iMX95/94/952. For u-boot FDT fixup, introduce a common function that each board needs this fixup could select OF_BOARD_FIXUP and implement board_fix_fdt to call imx9_uboot_fixup_by_fuse.

Fix ad-hoc tabs and spaces use, convert to tabs. Drop bogus duplicate asterisk from non-kerneldoc code comments. No functional change. Signed-off-by: Marek Vasut

imx: Remove hardcoded watchdog base address macros

2026-06-05T11:58:00Z

The watchdog base addresses are now obtained from the devicetree via ofnode_* functions. Remove the hardcoded macro definitions as they are no longer needed. Signed-off-by: Alice Guo Reviewed-by: Peng Fan

imx9: Add support for saving DDR training data to NVM

2026-05-15T20:31:39Z

DDR training data can be saved to NVM and be available to OEI at boot time, which will trigger QuickBoot flow. U-Boot only checks for data integrity (CRC32), while OEI is in charge of authentication when it tries to load the data from NVM. On iMX95 A0/A1, 'authentication' is done via another CRC32. On the other SoCs, authentication is done by using ELE to check the MAC stored in the ddrphy_qb_state structure. Supported platforms: iMX94, iMX95, iMX952 (using OEI) Supported storage types: eMMC, SD, SPI flash. Signed-off-by: Viorel Suman Signed-off-by: Ye Li Signed-off-by: Simona Toaca

imx9: scmi: Support iMX95/94/952 secondary boot

2026-05-15T20:31:39Z

When ROM boots from secondary container set, SPL should select correct offset to load u-boot-atf container. The implementation uses ROM passover information: 1) For non-eMMC boot partition device, use image offset in ROM passover data to get u-boot-atf container offset. 2) For eMMC boot partition device, use boot stage (secondary) in ROM passover data to select correct eMMC boot partition for u-boot-atf container.
