37 Describes the total size of the MCU or OCMC MSRAM present on
38 the SoC in use. This doesn't specify the total size of SPL as
39 ROM can use some part of this RAM. Once ROM gives control to
40 SPL then this complete size can be usable.

76 Address at which ROM stores the value which determines if SPL
77 is booted up by primary boot media or secondary boot media.
80 string "Key used to generate x509 certificate"
82 This option enables to provide a custom key that can be used for
83 generating x509 certificate for spl binary. If not needed leave
84 it blank so that a random key is generated and used.
86 config SYS_K3_BOOT_CORE_ID
91 bool "Activate to allow for an early console during SPL"
94 Turn this option on to enable an early console functionality in SPL
95 before the main console is being brought up. This can be useful in
96 situations where the main console is dependent on System Firmware
97 (SYSFW) being up and running, which is usually not the case during
98 the very early stages of boot. Using this early console functionality
99 will allow for an alternate serial port to be used to support things
100 like UART-based boot and early diagnostic messages until the main
101 console is ready to get activated.
103 config K3_EARLY_CONS_IDX
104 depends on K3_EARLY_CONS
105 int "Index of serial device to use for SPL early console"
108 Use this option to set the index of the serial device to be used
109 for the early console during SPL execution.
115 config K3_SYSFW_IMAGE_NAME
116 string "File name of SYSFW firmware and configuration blob"
117 depends on K3_LOAD_SYSFW
120 Filename of the combined System Firmware and configuration image tree
121 blob to be loaded when booting from a filesystem.
123 config K3_SYSFW_IMAGE_MMCSD_RAW_MODE_SECT
124 hex "MMC sector to load SYSFW firmware and configuration blob from"
125 depends on K3_LOAD_SYSFW && SYS_MMCSD_RAW_MODE_U_BOOT_USE_SECTOR
128 Address on the MMC to load the combined System Firmware and
129 configuration image tree blob from, when the MMC is being used
130 in raw mode. Units: MMC sectors (1 sector = 512 bytes).
132 config K3_SYSFW_IMAGE_MMCSD_RAW_MODE_PART
133 hex "MMC partition to load SYSFW firmware and configuration blob from"
134 depends on K3_LOAD_SYSFW && SYS_MMCSD_RAW_MODE_U_BOOT_USE_PARTITION
137 Partition on the MMC to the combined System Firmware and configuration
138 image tree blob from, when the MMC is being used in raw mode.
140 config K3_SYSFW_IMAGE_SIZE_MAX
141 int "Amount of memory dynamically allocated for loading SYSFW blob"
142 depends on K3_LOAD_SYSFW
143 default 163840 if SOC_K3_AM625 || SOC_K3_AM62A7
146 Amount of memory (in bytes) reserved through dynamic allocation at
147 runtime for loading the combined System Firmware and configuration image
148 tree blob. Keep it as tight as possible, as this directly affects the
149 overall SPL memory footprint.
151 config K3_SYSFW_IMAGE_SPI_OFFS
152 hex "SPI offset of SYSFW firmware and configuration blob"
153 depends on K3_LOAD_SYSFW
156 Offset of the combined System Firmware and configuration image tree
157 blob to be loaded when booting from a SPI flash memory.
159 config SYS_K3_SPL_ATF
160 bool "Start Cortex-A from SPL"
161 depends on SPL && CPU_V7R
163 Enabling this will try to start Cortex-A (typically with ATF)
166 config K3_ATF_LOAD_ADDR
167 hex "Load address of ATF image"
170 The load address for the ATF image. This value defaults to 0x70000000
171 if not provided in the board defconfig file.
174 bool "Separate DM firmware image"
175 depends on SPL && CPU_V7R && (SOC_K3_J721E || SOC_K3_J721S2 || SOC_K3_AM625 || SOC_K3_AM62A7) && !CLK_TI_SCI && !TI_SCI_POWER_DOMAIN
178 Enabling this will indicate that the system has separate DM
179 and TIFS firmware images in place, instead of a single SYSFW
180 firmware. Due to DM being executed on the same core as R5 SPL
181 bootloader, it makes RM and PM services not being available
182 during R5 SPL execution time.
