SPDX-License-Identifier: GPL-2.0 - -DeviceTree Booting ------------------- - - There is one single 32bit entry point to the kernel at code32_start, - the decompressor (the real mode entry point goes to the same 32bit - entry point once it switched into protected mode). That entry point - supports one calling convention which is documented in - Documentation/x86/boot.rst - The physical pointer to the device-tree block is passed via setup_data - which requires at least boot protocol 2.09. - The type filed is defined as - - #define SETUP_DTB 2 - - This device-tree is used as an extension to the "boot page". As such it - does not parse / consider data which is already covered by the boot - page. This includes memory size, reserved ranges, command line arguments - or initrd address. It simply holds information which can not be retrieved - otherwise like interrupt routing or a list of devices behind an I2C bus. |
