  - [ ] Currently XT Development Kit (XTDK) is a garbage. It should be cleaned up the way, it contains all structures
        and definitions, as well as all routines that are exported and can be used by other components or software
        dynamically linked. All other routines should be available as well in some form, as some libraries can share

 ### XTLDR
  - [ ] Rewrite memory mapping and paging support in bootloader to make it more flexible and architecture independent.

 ### XTOSKRNL
  - [ ] Implement mechanism for detecting CPU features and checking hardware requirements. If CPU does not meet
        requirements, it should cause a kernel panic before any non-supported instruction is being used.
