Multi-target architecture implementation:
each root source code directory presents the one
*INTERFACE* target to it's subdirectory subtargets
that link only as *STATIC* library.
For instance, *arch* directory presents *Architecture* target
then *Architecture* target has *CPUID*, *IO*, *PORT*
and etc. dependencies
Exact order of linking targets is: boot.o CRTIBUNDLE <TARGETS> CRTNBUNDLE.
Sequence destruction cause to UB. Please to pay attention to this.
TODO
- Debug information
- Build type
- Toolchain file
- Image creation
- Build by WinGW compiler on Windows platform (optional)

Global variables initialization implementation2025-12-20T12:39:05ZAlexey Gavrilovalexey.gavrilov@mail.com2025-12-20T12:39:05Zurn:sha1:a4dea4148157a94a9143dbbd92fdd88b4358676c
User implementation of C runtime library objects (`crti.s` and `crtn.s`)
for initialization (termination functionality are ignored).
Changing files order passed to the linker. Rough order is:
boot.s crti.o crtbegin.o other-link-objects.o crtend.o crtn.o

Linker script rework2025-12-20T07:16:47ZAlexey Gavrilovalexey.gavrilov@mail.com2025-12-17T07:13:08Zurn:sha1:eb6a12e18d45879ec383921f0c7378120b71d159
`memory.ld` is a architecture-dependent ld config provides some general
symbols which every `memory.ld` config must assign
and memory regions associated with each output section.
'linker.ld' config file presents segments configuration.
Multiboot section filling move in the 'linker.ld' file.
Recommendation for further patches: controlled logic implementation for multiboot
version and header/entries in build configuration tool (CMake or
make). For instance, multiboot version and video mode selection
through variable passing in build system:
`cmake ... -DMULTIBOOT_VERSION=2 -DMULTIBOOT_VIDEO_MODE=TEXT_VIDEO_MODE`
or
'export MULTIBOOT_VERSION=2; export MULTIBOOT_VIDEO_MODE=TEXT_VIDEO_MODE'.
Then build system do proper filling of `.multiboot` section depends
on passing variables.
