other:
- In16 -> rt_in16 in BootKit.h
why?
- Silent corruption with other disk backends.
- Better off starting with new work based on this backend but with bug fixes.

what?
- AHCI now writes to disk, forgot to do it.
- Codebase's architecutre has been used to reuse the Generic+AHCI driver in SysChk for AHCI. (tradeoff is 256K in size instead of 36K)
- DriveMgr now detects EPM.
- And HeFS is still being worked on.

- Currently working on VEPM and adapting it to SysChk.
- Refactor DriveMgr for VEPM.
- Fix warnings in HeFS.cc, ALIGN(8) on HeFS.h
- Update PIO modules to use VEPM.

- Renamed Boot.S → BootNetStartup.S and SysChk/Boot.S → SysChkStartup.S for clarity
- Replaced BOOTNET_INTERNET_HEADER.ImpliesEEPROM with ImpliesProgram to better reflect the generic reprogramming intent
- Introduced `bootnet_read_udp_packet()` stub for future UDP packet parsing from bootnet.json
- Minor alignment and comment fixes in various headers (CoreBoot, EPM, Json)
- Updated HalPagingMgr to use PageStore instead of NE_PAGE_STORE
- Boot time now prints cycles since start; triggered fs_init_nefs() earlier during HAL init
- Prep for extended MBCI and master structure support in COREBOOT_LINEAR_EXEC
- Numerous cleanups across DMA, NewKit, and Json parsing to prep for extended patching and block-level bootstrap
This lays groundwork for richer NetBoot infrastructure in NeKernel and aligns naming and structure conventions across subsystems.

- Consolidated CoreGfx headers:
* Renamed `FBMgr.h` to `CoreGfx.h`
* Renamed `TextMgr.h` → `TextGfx.h`, `MathMgr.h` → `MathGfx.h`, and `AccessibilityMgr.h` → `CoreAccess.h`
* Updated all includes across bootloader, HAL, and kernel to use new names
- Standardized EFI entrypoint:
* Replaced `Main` with `ModuleMain` in EFI boot sources and linker flags
* Updated GDB and build scripts accordingly
- Improved AHCI identify logic:
* Added full 48-bit LBA extraction (words 100–102)
* Fallback to 28-bit if LBA48 not supported
* Refactored `drv_get_size` and `drv_std_detected` into separate `#ifdef __AHCI__` region
- DiskImage framework improvements:
* Namespaced API into `DI` namespace
* Split implementation: `DiskImage+EPM.cc` and `DiskImage+NeFS.cc`
* Updated CLI tool accordingly
- KernelTest framework:
* Namespaced macros and classes with `KT_`
* Changed test result to use `MUST_PASS` and boolean return
- Misc:
* Corrected minor logic in `NetworkDevice::Name()`
* Bumped down KernelKit and NewKit versions to 0.0.1
* Renamed `HalUtils.asm` → `HalUtilsAPI.asm`

This patch begins a major cleanup and enhancement of AHCI I/O handling:
- Refactored AHCI command setup logic to prepare FIS and PRDT entries more correctly.
- Fixed miscalculation of 48-bit LBA extraction from IDENTIFY response.
- Rewrote PRDT loop to increment physical address per entry instead of recomputing offsets.
- Replaced read/write/identify branching with unified ternary logic for clarity.
- Ensured proper stopping and reinitialization of command engine before issuing commands.
- Explicitly remap and zero command list base, FIS base, and command table areas.
- Made command slot lookup more robust.
- Added fallback wait after command completion to avoid SRBSY/SRDRQ residue.
- Dropped misused `YES` flag in read/write call sites — now passed only when needed.
Also includes:
- Minor cleanup in `BootKit.h` (whitespace).
- NeFS debug message clarified to avoid accidental fork overwrites.
This is a **work-in-progress** rework of the AHCI path. Next steps will involve:
- More robust error recovery.
- Support for non-512 sector drives.
- Support for multiple ports and NCQ.

Collapse the EFI namespace into Boot to unify BootZ's interface for firmware
handling. This simplifies calls to functions like Stop(), ThrowError(),
and ExitBootServices(), and improves consistency across boot modules.
Also rename SysChk/Module.cc to SysChk/SysChk.cc for naming consistency
with other modules.
Improve NetBoot fallback path in BootEFI:
- Ensure netboot.sys is read before ExitBootServices() to avoid allocation
issues after exiting firmware services.
- Reuse reader and thread objects if kernel boot fails.
- Update both AMD64 and ARM64 paths to follow the same logic.
Update all call sites to use Boot:: instead of EFI::.
Fixes: broken error handling and memory reads after ExitBootServices()
