18 config SYS_K3_NON_SECURE_MSRAM_SIZE
20 default 0x80000 if SOC_K3_AM6
21 default 0x100000 if SOC_K3_J721E
23 Describes the total size of the MCU MSRAM. This doesn't
24 specify the total size of SPL as ROM can use some part
25 of this RAM. Once ROM gives control to SPL then this
26 complete size can be usable.
28 config SYS_K3_MAX_DOWNLODABLE_IMAGE_SIZE
30 default 0x58000 if SOC_K3_AM6
31 default 0xc0000 if SOC_K3_J721E
33 Describes the maximum size of the image that ROM can download
36 config SYS_K3_MCU_SCRATCHPAD_BASE
38 default 0x40280000 if SOC_K3_AM6
39 default 0x40280000 if SOC_K3_J721E
41 Describes the base address of MCU Scratchpad RAM.
43 config SYS_K3_MCU_SCRATCHPAD_SIZE
45 default 0x200 if SOC_K3_AM6
46 default 0x200 if SOC_K3_J721E
48 Describes the size of MCU Scratchpad RAM.

52 default 0x41c7fbfc if SOC_K3_AM6
53 default 0x41cffc00 if SOC_K3_J721E
55 Address at which ROM stores the value which determines if SPL
56 is booted up by primary boot media or secondary boot media.
59 string "Key used to generate x509 certificate"
61 This option enables to provide a custom key that can be used for
62 generating x509 certificate for spl binary. If not needed leave
63 it blank so that a random key is generated and used.
65 config SYS_K3_BOOT_CORE_ID
70 bool "Activate to allow for an early console during SPL"
73 Turn this option on to enable an early console functionality in SPL
74 before the main console is being brought up. This can be useful in
75 situations where the main console is dependent on System Firmware
76 (SYSFW) being up and running, which is usually not the case during
77 the very early stages of boot. Using this early console functionality
78 will allow for an alternate serial port to be used to support things
79 like UART-based boot and early diagnostic messages until the main
80 console is ready to get activated.
82 config K3_EARLY_CONS_IDX
83 depends on K3_EARLY_CONS
84 int "Index of serial device to use for SPL early console"
87 Use this option to set the index of the serial device to be used
88 for the early console during SPL execution.
94 config K3_SYSFW_IMAGE_NAME
95 string "File name of SYSFW firmware and configuration blob"
96 depends on K3_LOAD_SYSFW
99 Filename of the combined System Firmware and configuration image tree
100 blob to be loaded when booting from a filesystem.
102 config K3_SYSFW_IMAGE_MMCSD_RAW_MODE_SECT
103 hex "MMC sector to load SYSFW firmware and configuration blob from"
104 depends on K3_LOAD_SYSFW && SYS_MMCSD_RAW_MODE_U_BOOT_USE_SECTOR
107 Address on the MMC to load the combined System Firmware and
108 configuration image tree blob from, when the MMC is being used
109 in raw mode. Units: MMC sectors (1 sector = 512 bytes).
111 config K3_SYSFW_IMAGE_MMCSD_RAW_MODE_PART
112 hex "MMC partition to load SYSFW firmware and configuration blob from"
113 depends on K3_LOAD_SYSFW && SYS_MMCSD_RAW_MODE_U_BOOT_USE_PARTITION
116 Partition on the MMC to the combined System Firmware and configuration
117 image tree blob from, when the MMC is being used in raw mode.
119 config K3_SYSFW_IMAGE_SIZE_MAX
120 int "Amount of memory dynamically allocated for loading SYSFW blob"
121 depends on K3_LOAD_SYSFW
124 Amount of memory (in bytes) reserved through dynamic allocation at
125 runtime for loading the combined System Firmware and configuration image
126 tree blob. Keep it as tight as possible, as this directly affects the
127 overall SPL memory footprint.
129 config SYS_K3_SPL_ATF
130 bool "Start Cortex-A from SPL"
131 depends on SPL && CPU_V7R
133 Enabling this will try to start Cortex-A (typically with ATF)
