Function get_bootinfo 

pub const fn get_bootinfo() -> &'static BootInfo

Get the bootinfo.

The BootInfo is pre-copied & fixed at the dedicated constant physical address 0x10000 by UEFI boot stage, never modified nor released in kernel lifetime.

Safety

Caller must ensure before invoking:

1. Address 0x10000 is allocated & filled with valid initialized BootInfo;
2. This range is reserved, never overwritten/freed by kernel/UEFI;
3. No mutable aliasing exists for this memory region.

These steps are already guaranteed by the bootloader, so invocation is generally safe in normal kernel runtime.

Returns

• &'static BootInfo: immutable static reference to the pre-filled BootInfo
