@note
This commit doesn't provide the complet CMake support, because many
improvements need to be done in the vxSDK. You can only build the SDL2 board
by hardcoding environment variables (the `vxsdk.toml file is not fonctional`)
The "shared" forms of the library will be handled as a Virtual Dynamic Shared
Object (vDSO) and will be common for all board. This is not supported yet.
@add
> [CMakeLists.txt]
¦ support project architecture
¦ support project configuration file
¦ support SDL2 board (static-only)
> [scripts]
¦ provide proper API
¦ proper isolate the board manipulation
¦ proper isolate the "library format" selection (static or vdso)
¦ generate a CMake file instead of Makefile one
@update
> [common]
¦ rename 'board/' to 'boards/'
¦ move 'assets/', 'src/' and 'include' in 'kernel/'
¦ remove old makefile
¦ in 'boards/<board-name>' proper isolate :
¦ board description : `board.toml`
¦ board file to install : e.i `fxcg50.ld`
¦ board source file : `src`
¦ board include : `include`
> [configure]
¦ proper refacto the script
¦ proper isolation between vxSDK use and user
@fix
> [kernel/src]
¦ [drivers/common/sdl2]
¦ [keyboard] remove unused object
¦ [keyboard] proper table size declaration
¦ [sdl2] fix return value
¦ [timer] fix return value
¦ [modules]
¦ [dstack] fix return value
¦ [hypervisor] fix return value

| rename internal functions
<> src/module/display
| Now, by default, DSTACK_CALL() create a pointer on a dstack_call_t
| use dsubimage dstack primitive in dimage()
@fix
<> board/fxcg50/fxcg50.ld
| remove the IL-memory and allow only the X-memory area. This because the
bootloader uses the IL-memory for DMA transfer and other "low-level"
routine used by Gint.
Moreover, I originally try to move each "display-driver" in this place,
but after some profiling and tests, the dclear()/dupdate() combo went from
9155us up to 33250us (for many reason). So, I keep this area free, but I
moved-back from RAM display routines.
<> board/fxcg50/initialize
| remove "section" copy. This role has been delegated to the bootload (vxBoot)
because, in the final ELF file generated by GCC, many relocalization
information for the IL/X memory has been set and the bootloader cannot
performs general relocalization.
So, all "special section/memory" displacement has been moved in the
bootloader and we don't have to worrying about the section copy.
<> src/drivers/mpu/sh/sh7305/tmu
| fix delay calculation in timer reload primitive
| disable interruption for profiling timer
<> src/module/dislay/
| fix shader index used during the dstack_render()
| fix many errors in dimage() shadow render (WIP)
