remoteproc: imx_rproc: Add support for i.MX93 CM33

2025-11-04T15:45:30Z

Introduce remote processor configuration for the i.MX93 Cortex-M33 core. This patch adds: - Address translation table (ATT) for i.MX93, including TCM (secure and non-secure) and DDR regions. - A new device configuration structure `imx_rproc_cfg_imx93` using SMC method and ARM SMC ops. - Device tree match entry for "fsl,imx93-cm33" This enables remoteproc framework to properly initialize and manage the Cortex-M33 core on i.MX93 platforms.

remoteproc: imx_rproc: Support i.MX8MQ/M

2025-11-04T15:45:30Z

i.MX8MQ/M use MMIO based method to directly configure SRC registers to start/stop M4. Add mmio ops to start/stop/is_running. Add i.MX8MQ cfg data, i.MX8MN reuses i.MX8MQ data. Reviewed-by: Ye Li Signed-off-by: Peng Fan

remoteproc: Add imx_rproc driver to support NXP i.MX8MP/N

2025-11-04T15:45:30Z

Support i.MX8MP/N with start/stop/device_to_virt/is_running/load implemented. The device static configuration is mostly reused from Linux Kernel with adapation to U-Boot dm_rproc_ops. The booting method: - load mmc 2:2 0x90000000 /lib/firmware/imx8mp_m7_DDR_rpmsg_lite_str_echo_ rtos.elf - rproc load 0 0x90000000 ${filesize} - rproc start 0 Reviewed-by: Ye Li Signed-off-by: Peng Fan

remoteproc: Extend device_to_virt with a is_iomem parameter

2025-11-04T15:45:30Z

Some areas needs to be initialized by using memcpy_toio and memset_io. Following Linux Kernel commit: 40df0a91b2a5 ("remoteproc: add is_iomem to da_to_va"), add this to U-Boot. Reviewed-by: Ye Li Signed-off-by: Peng Fan

remoteproc: k3: update compatible for am654 syscon

2025-08-21T19:27:53Z

The existing compatible name for U-Boot's k3 system controller driver i.e "ti,am625-system-controller" has been added to linux[1] device-tree. This compatible in kernel is meant for configuring the Control Module registers (CTRL_MMR0). However in U-Boot, the matching driver was being used to load the system firmware on the secure M-cores by the R5 SPL and therefore must be updated to a different compatible to avoid conflicts. Therefore, this patch renames all references of the compatible to "ti,am654-tisci-rproc-r5". The "-r5" is appended so as to avoid any future conflicts since r5 specific compatibles should only be useful for U-Boot.

remoteproc: k3-r5: Add support for single cpu mode

2025-08-21T16:02:52Z

Add early boot support for AM64 single cpu mode configuration. In single CPU mode the 2nd core of the R5F cluster can't be used or unavailable. Signed-off-by: Hari Nagalla

remoteproc: k3-r5: Ensure ret is initialised

2025-08-19T17:25:56Z

In k3_r5f_split_reset and k3_r5f_unprepare ret may not have been assigned to before the code reaches the return ret at the function exit. This issue was found by Smatch. Signed-off-by: Andrew Goodbody

remoteproc: ti_k3_arm64: Cannot set or compare u8 to 16bits

2025-08-19T17:25:56Z

In the struct ti_sci_proc the fields proc_id and host_id are declared as u8 so cannot be set to nor compared with a macro defined with a value using 16 bits. Change the macro to only use 8 bits to make the code work as expected. This issue was found by Smatch. Signed-off-by: Andrew Goodbody
