− | For detailed information, please read the file in the delivered U-Boot code = {{CodeSource | U-Boot | board/st/stm32mp1/README}}
| |
− | | |
− | Also available in official U-Boot Git.
| |
− | | |
− | Code :
| |
− | * {{CodeSource | U-Boot | arch/arm/mach-stm32mp}}: arch specific code for {{MicroprocessorDevice | device=Class}}
| |
− | * {{CodeSource | U-Boot | board/st/stm32mp1}}: generic STMicroelectronics board for {{MicroprocessorDevice | device=1}}
| |
− | * drivers/*/*stm32* : drivers
| |
− | | |
− | Configuration Files:
| |
− | * defconfig file
| |
− | ** {{CodeSource | U-Boot | configs/stm32mp15_basic_defconfig}}
| |
− | ** {{CodeSource | U-Boot | configs/stm32mp15_optee_defconfig}}

− | ** {{CodeSource | U-Boot | include/configs/stm32mp1.h}}
| |
− | * Device tree in {{CodeSource | U-Boot | arch/arm/dts }}
| |
− | ** stm32mp157*-<board>.dts : same as kernel
| |
− | ** stm32mp157*-<board>-u-boot.dtsi : addition for u-boot ( <<device tree>>-u-boot.dtsi automatically included in build process)

| |
− | | |
− | Each [[Boot_chains_overview|boot chain]] is supported by one [[U-Boot_overview#Kbuild|U-Boot configuration with defconfig]]
