be795d5812 Prekernel: Use physical addresses for some of the BootInfo parameters 
The kernel would just turn those virtual addresses into physical
addresses later on, so let's just use physical addresses right from the
start.

dd42093b93 Kernel: Move boot info declarations to a header file 
Instead of manually redeclaring those variables in various files this
now adds a header file for them.

7e94b090fe Kernel: Introduce basic pre-kernel environment 
This implements a simple bootloader that is capable of loading ELF64
kernel images. It does this by using QEMU/GRUB to load the kernel image
from disk and pass it to our bootloader as a Multiboot module.

The bootloader then parses the ELF image and sets it up appropriately.
The kernel's entry point is a C++ function with architecture-native
code.
