- Discard the RTC interrupt handler for MSVC builds. Unfortunately GAS doesn't have such a feature
- Remove the unused systimer.S file from MiniHAL compilation
Skip x86 BIOS emulator initialization on EFI boots by having FreeLdr populate EFI boot state in the loader block and making HAL consume it.
This keeps BIOS behavior unchanged while avoiding legacy BIOS/INT10 setup in the EFI path and preventing early EFI boot failures caused by entering the BIOS emulator path at all.
* [FREELDR] Mark noreturn functions
* [FREELDR] Compile hw debugging support code only in debug builds
- Make BREAKPOINT() portable
* [FREELDR] Consolidate identical names into a single string
* [FREELDR] Use intrinsics for string I/O operations on x86 and x64
Stop them being pulled in from a static minihal library
* [MINIHAL] Exclude unnecessary portio dependency

Introduce the initial changes needed to get other processors up and into kernel mode.
This only supports x86 as of now but is the first real step towards using other system processors.
This will be needed for compatibility with x86 Windows Vista/7 videoprt.sys builds.
Might be also useful in future for platforms (x86 , ...) where V86 mode is not available or buggy.

Reference: https://wiki.osdev.org/PCI#Address_and_size_of_the_BAR
To determine the amount of address space needed by a PCI device,
you must save the original value of the BAR, write a value
of all 1's to the register, then read it back.
Note: 64-bit BARs are not supported yet.
* Call HalInitializeBios both in phase 0 and 1
* In phase 0 allocate some physical memory, instead of using arbitrary hardcoded pages, that then end up as page tables and get filled with VESA tables
- Change INIT_FUNCTION and INIT_SECTION to CODE_SEG("INIT") and DATA_SEG("INIT") respectively
- Remove INIT_FUNCTION from function prototypes
- Remove alloc_text pragma calls as they are not needed anymore
* Add an NDK header to define INIT_FUNCTION/INIT_SECTION globally
* Use _declspec(allocate(x)) and _declspec(code_seg(x)) on MSVC versions that support it
* Use INIT_FUNCTION on functions only and INIT_SECTION on data only (required by MSVC)
* Place INIT_FUNCTION before the return type (required by MSVC)
* Make sure declarations and implementations share the same modifiers (required by MSVC)
* Add a global linker option to suppress warnings about defined but unused INIT section
* Merge INIT section into .text in freeldr
