Good morning.I am studying Device Tree of Kernel.I use an ARM board.According to the information of Operation Mode(Booting Mode) Register, the device medium used for booting the ARM board is set differently.  Example)   Operation Mode(Booting Mode) Register: 0x01 -> eMMc Booting      Operation Mode(Booting Mode) Register: 0x02 -> SD Booting      Operation Mode(Booting Mode) Register: 0x03 -> USB Booting  Is there an example of using this information in the Kernel's Device Tree?Or is there an appropriate example to read Operation Mode (Booting Mode) from Kernel?
Is there information such as Operation Mode (Booting Mode) in the device tree?
kernel;proc;system information;device tree
