Helper	Functions
UBA	Debug Protocol Support
Raise	TPL to HIGH_LEVEL to serialize access during protocol lookup.
OldTpl	= gBootServices->RaiseTPL (TPL_HIGH_LEVEL);
Locate	the UBA debug protocol for assertion output.
Status	= gBootServices->LocateProtocol (
Call	the assertion function at protocol + 0x08 (index 1).
HOB	List Support
Return	early if there are no configuration table entries.
if	(gSystemTable->NumberOfTableEntries == 0) {
Iterate	through configuration table entries to find gEfiHobListGuid.
for	(Index = 0; Index < gSystemTable->NumberOfTableEntries; Index++) {
Found	the HOB list - cache and return the pointer.
gHobList	= Entry->VendorTable;
HOB	list not found - report error and assert.
DEBUG	((DEBUG_ERROR, "\nASSERT_EFI_ERROR (Status = %r)\n", EFI_NOT_FOUND));
Platform	Detection & Slot Data Initialization
Save	current NMI state and select CMOS register 0x4B.
Register	0x4B holds platform configuration data.
NmiSave	= IoRead8 (0x70);
Handle	special CMOS values:
if	(CmosValue > 3) {
Read	hardware strap from fixed MMIO address.
Bit	1 selects platform type; OR with 1 for default.
CmosValue	**= (MmioRead32 (0xFDAF0490) & 2)	1;**
Map	CMOS value to platform type flags:
Value	**1 -> Flag	0x00000004**
Other	**-> Flag	0x00000006**
if	((CmosValue - 1) <= 0xFD) {
Dispatch	to UBA protocol slot data init handler (index 0 = first function pointer).
The	protocol's first function handles platform-specific init dispatch:
Result	*= ((UINTN (EFIAPI )(UINTN, CHAR8* , UINTN))(**
Entry	Point
Store	global EFI handles.
gImageHandle	= ImageHandle;
Validate	input parameters (uses UBA assert for output).
ASSERT	(ImageHandle != NULL);
Locate	the HOB list from the system table configuration table.
LocateHobList	();
Perform	platform detection and slot data initialization
via	the UBA framework. This checks CMOS register 0x4B
and	dispatches to the appropriate platform type handler.
PlatformSlotDataInit	(0x80000000, "UBA:SlotDataUpdate-TypeNeonCityEPECB\n");
Locate	the UBA slot data update protocol.
LocalVariable	= 0;
Register	32-byte slot configuration (single slot, referenced by gSlotConfigGuid32).
Status	*= ((EFI_STATUS (EFIAPI )(VOID* , EFI_GUID , VOID , UINTN))(**
Register	40-byte slot configuration (dual slot, referenced by gSlotConfigGuid40).
