^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  6)   There is one single 32bit entry point to the kernel at code32_start,
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  7)   the decompressor (the real mode entry point goes to the same  32bit
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  8)   entry point once it switched into protected mode). That entry point
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  9)   supports one calling convention which is documented in
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 10)   Documentation/x86/boot.rst
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 11)   The physical pointer to the device-tree block is passed via setup_data
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 12)   which requires at least boot protocol 2.09.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 13)   The type filed is defined as
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 14) 
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 15)   #define SETUP_DTB                      2

^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 17)   This device-tree is used as an extension to the "boot page". As such it
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 18)   does not parse / consider data which is already covered by the boot
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 19)   page. This includes memory size, reserved ranges, command line arguments
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 20)   or initrd address. It simply holds information which can not be retrieved
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 21)   otherwise like interrupt routing or a list of devices behind an I2C bus.
