MB2 BCT Misc Configuration

This section provides additional information about the MB2 BCT Misc configuration file.

MB2 Feature Fields

Here is a list of the Boolean flags that enable or disable functionality in MB2:

Field	Description
`disable-cpu-l2ecc`	If this property is present, CPU L2 ECC is disabled. Otherwise, it is enabled.
`enable-combined-uart`	If this property is present, the combined uart is enabled. Otherwise, it is disabled.
`spe-uart-instance`	UART controller that is used for the combined UART by the SPE.

MB2 Firmware Data

The MB2 firmware configuration is applied in the following way:

/ {
   mb2-misc {
       <firmware-type> {
          <parameter> = <value>;
       };
   };
};

Where firmware-type is one of the following types:

cpubl
ape-fw
bpmp-fw
rce-fw
sce-fw
camera-task-fw
apr-fw

<parameter> is one of the parameters from the following table:

Parameters	Description
`enable`	If this parameter is present, the loading of firmware from MB2 is enabled. Otherwise, the firmware loading is disabled.
`ast-va`	Virtual address for the firmware carveout in the BPMP-R5 address space.
`load-offset`	Offset in firmware carveout where firmware binary is loaded.
`entry-offset`	Offset of the firmware entry point in the firmware carveout.

Here is an example of the MB2 Misc DTS configuration file:

/dts-v1/;

#include "tegra234-mb2-bct-common.dtsi"

/ {
        mb2-misc {
                enable_pva_fw = <0>;
            eeprom {
                    cvm_eeprom_i2c_instance = <0>;
                    cvm_eeprom_i2c_slave_address = <0xa0>;
                        cvm_eeprom_read_size = <0x100>;
                    cvb_eeprom_i2c_instance = <0x0>;
                    cvb_eeprom_i2c_slave_address = <0xae>;
                    cvb_eeprom_read_size = <0x100>;
            };
        };
};
