//! The x86 boot module defines the entrypoints of Asterinas and
//! the corresponding headers for different x86 boot protocols.
//!
//! We directly support
//!
//! - Multiboot
//! - Multiboot2
//! - Linux x86 Boot Protocol
//!
//! without any additional configurations.
//!
//! Asterinas differentiates the boot protocol by the entry point
//! chosen by the boot loader. In each entry point function,
//! the universal callback registration method from
//! `crate::boot` will be called. Thus the initialization of
//! boot information is transparent for the upper level kernel.
