Global	data: IIO configuration platform data header
This	48-byte structure is the Platform IIO config descriptor dispatched to
each	UBA protocol instance. The bifurcation mapping table follows at the
byte	offset indicated by BifurMapEntryCount acting as the offset (0x3C).
STATIC	CONST IIO_CFG_PLATFORM_DATA_HEADER mIioCfgPlatformData = {
0x4F494950	.Revision = 1
3424	bytes total config
60	bifurcation entries (offset 0x3C)
1292	slot config entries
3120	SMBUS config entries
252	reserved
Static	variables
GUID	definitions used by this driver
The	HOB list is identified by gEfiHobListGuid, but the specific HOB
entry	this driver looks for matches the GUID at 0xC18.
STATIC	CONST EFI_GUID mIioCfgHobTargetGuid = IIO_CFG_HOB_GUID;
Debug	protocol lookup (cached)
CMOS	debug output
Access	CMOS debug routing register
IoWrite8	**(0x70, (IoRead8 (0x70) & 0x80)	0x4B);**
If	value == 0, check MMIO-based debug enable
if	(CmosValue == 0) {
Route	to UBA protocol debug output if available
UbaProtocol	= GetUbaConfigProtocol ();
Protocol	interface at offset +8 is the DebugPrint function
ASSERT	handler
but	here we call it in ASSERT mode (no VA_LIST needed)
Unaligned	memory access
GUID	comparison (as two UINT64 values)
HOB	list retrieval
Return	cached result
if	(mIioCfgHobList != NULL) {
SystemTable	HOB fields:
HobCount	*= (UINTN* )((UINT8 )gST + 0x68);*
Linear	scan through HOB array (each entry 24 bytes)

IIO	configuration platform data registration
Locate	the UBA IIO configuration protocol

Retrieve	the IIO configuration HOB list (locates HOBs in SystemTable)
GetIioConfigHobList	();
Print	platform identification string
