From: Peng Fan <[email protected]> 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.
