Create a foundational memory management system to handle dynamic memory allocation. This includes both physical and virtual memory management components.

Scope of work:

Physical Memory Management.
- Memory Map Creation:
  - Retrieve and interpret the memory map provided by the boot loader.
  - Identify available, reserved, and hardware-specific memory regions.
- Physical Memory Allocator:
  - Implement a bitmap or linked list-based allocator to manage physical memory frames/pages.
  - Implement functions to allocate and free memory frames for kernel and other system components.
Virtual Memory Management.
- Paging Structure Setup:
  - Initialize paging to enable virtual memory.
  - Map necessary kernel addresses to physical addresses.
- Virtual Memory Allocator:
  - Develop functions similar to malloc and free for dynamic memory allocation in the kernel space.
  - Handle fragmentation and efficient usage of virtual address space.
Memory Protection.
- Implement access permissions for different memory regions (RWX).
