This doesn't specify the total size of SPL as ROM can use some part of this RAM. Once ROM gives control to SPL then this complete size can be usable. config SYS_K3_MAX_DOWNLODABLE_IMAGE_SIZE hex default 0x58000 if SOC_K3_AM6 default 0xc0000 if SOC_K3_J721E || SOC_K3_J721S2 default 0x180000 if SOC_K3_AM642 default 0x38000 if SOC_K3_AM625 help Describes the maximum size of the image that ROM can download from any boot media. config SYS_K3_MCU_SCRATCHPAD_BASE hex default 0x40280000 if SOC_K3_AM6 default 0x40280000 if SOC_K3_J721E || SOC_K3_J721S2 help Describes the base address of MCU Scratchpad RAM. config SYS_K3_MCU_SCRATCHPAD_SIZE hex default 0x200 if SOC_K3_AM6 default 0x200 if SOC_K3_J721E || SOC_K3_J721S2 help Describes the size of MCU Scratchpad RAM. config SYS_K3_BOOT_PARAM_TABLE_INDEX hex default 0x41c7fbfc if SOC_K3_AM6 default 0x41cffbfc if SOC_K3_J721E default 0x41cfdbfc if SOC_K3_J721S2 default 0x701bebfc if SOC_K3_AM642 default 0x43c3f290 if SOC_K3_AM625 help Address at which ROM stores the value which determines if SPL is booted up by primary boot media or secondary boot media. config SYS_K3_KEY string "Key used to generate x509 certificate" help This option enables to provide a custom key that can be used for generating x509 certificate for spl binary.

This can be useful in situations where the main console is dependent on System Firmware (SYSFW) being up and running, which is usually not the case during the very early stages of boot. Using this early console functionality will allow for an alternate serial port to be used to support things like UART-based boot and early diagnostic messages until the main console is ready to get activated. config K3_EARLY_CONS_IDX depends on K3_EARLY_CONS int "Index of serial device to use for SPL early console" default 1 help Use this option to set the index of the serial device to be used for the early console during SPL execution. config K3_LOAD_SYSFW bool depends on SPL config K3_SYSFW_IMAGE_NAME string "File name of SYSFW firmware and configuration blob" depends on K3_LOAD_SYSFW default "sysfw.itb" help Filename of the combined System Firmware and configuration image tree blob to be loaded when booting from a filesystem. config K3_SYSFW_IMAGE_MMCSD_RAW_MODE_SECT hex "MMC sector to load SYSFW firmware and configuration blob from" depends on K3_LOAD_SYSFW && SYS_MMCSD_RAW_MODE_U_BOOT_USE_SECTOR default 0x3600 help Address on the MMC to load the combined System Firmware and configuration image tree blob from, when the MMC is being used in raw mode.

Keep it as tight as possible, as this directly affects the overall SPL memory footprint. config K3_SYSFW_IMAGE_SPI_OFFS hex "SPI offset of SYSFW firmware and configuration blob" depends on K3_LOAD_SYSFW default 0x6C0000 help Offset of the combined System Firmware and configuration image tree blob to be loaded when booting from a SPI flash memory. config SYS_K3_SPL_ATF bool "Start Cortex-A from SPL" depends on SPL && CPU_V7R help Enabling this will try to start Cortex-A (typically with ATF) after SPL from R5. config K3_ATF_LOAD_ADDR hex "Load address of ATF image" default 0x70000000 help The load address for the ATF image.

Due to DM being executed on the same core as R5 SPL bootloader, it makes RM and PM services not being available during R5 SPL execution time. source "board/ti/am65x/Kconfig" source "board/ti/am64x/Kconfig" source "board/ti/am62x/Kconfig" source "board/ti/j721e/Kconfig" source "board/siemens/iot2050/Kconfig" source "board/ti/j721s2/Kconfig" endif
