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

imx: fix header inclusion guards

2023-05-31T14:11:46Z

It seems like the header inclusion guards for some IMX related headers were misspelled or got out of sync. Make the preprocessor symbols for the #ifndef and #define lines the same, so that the double inclusion protection works as expected. Signed-off-by: Andre Przywara Reviewed-by: Tom Rini

imx: ahab: Move imx9 and imx8ulp AHAB support together

2023-03-29T20:27:38Z

Use common file ele_ahab.c for i.MX9 and iMX8ULP AHAB support, since both of them use same sentinel ELE APIs Signed-off-by: Ye Li Reviewed-by: Peng Fan

imx: imx8ulp: Configure XRDC PDAC and MSC for DBD owner=S400 only

2023-03-29T18:15:42Z

This patch is used to support DBD owner fuse changed to S400 only. The XRDC PDAC2 for LPAV pbridge5 and MSC1/2/3 for GPIO and LPAV are not configured by S400 default setting. So these PDAC and MSC are invalid, only DBD owner can access the corresponding resources. We have to configure necessary PDAC and MSC for SPL before DDR initialization.

imx: imx8ulp: Adjust handshake to sync TRDC and XRDC completion

2023-03-29T18:15:42Z

To fit the DBD_EN fused part, we re-design the TRDC and XRDC assignment. M33 will be the TRDC owner and needs to configure TRDC. A35 is the XRDC owner, ATF will configure XRDC. The handshake between U-boot and M33 image is used to sync TRDC and XRDC configuration completion. Once the handshake is done, A35 and M33 can access the allowed resources in others domain. The handshake is needed when M33 is booted or DBD_EN fused, because both cases will enable the TRDC. If handshake is timeout, the boot will hang. We use SIM GPR0 to pass the info from SPL to u-boot, because before the handshake, u-boot can't access SEC SIM and FSB. Signed-off-by: Ye Li Reviewed-by: Jacky Bai

imx: imx8ulp: Get chip revision from Sentinel

misc: imx: S400_API: Move S400 MU and API to a common place

2022-07-26T09:29:00Z

Since iMX9 uses S401 which shares the API with iMX8ULP. So move S400 MU driver and API to a common place and selected by CONFIG_IMX_SENTINEL Signed-off-by: Ye Li Signed-off-by: Peng Fan

imx: imx9: support romapi
