Address	Name	Description
	ReturnNotFound
	ReadUnaligned64
	IsGuidMatch
	DebugAssert
	DebugPrint
	ModuleEntryPoint
Module	Global Variables
Image	handle for this driver.
Set	by ModuleEntryPoint from the ImageHandle parameter.
Asserted	non-NULL before use.
System	table pointer.
Set	by ModuleEntryPoint from the SystemTable parameter.
Boot	services pointer, extracted from gSystemTable->BootServices.
Runtime	services pointer, extracted from gSystemTable->RuntimeServices.
Asserted	non-NULL before use (cached but not called directly by this module).
Cached	DebugLib protocol interface pointer.
Initialized	on first call to GetDebugProtocol().
Cached	HOB list pointer.
Initialized	on first call to GetHobList().
Cached	CMOS debug level byte from register 0x4B.
Data	Section Contents
1	.DataSize = SETUP_CONFIG_DATA_SIZE, // 0x48C
0x48C	};
Function	Implementations
Environment	validation: allocate and free a small pool buffer
to	verify boot services are responding.
Boot	services appear broken	return NULL
Locate	the DebugLib protocol
Read	CMOS register 0x4B for board type / debug level
Interpret	the board type value
Value	> 3: if zero, look up fallback
Use	MMIO board configuration register as fallback
Set	the error level filter based on board type
Error	+ Warning + Info
Error	only
If	the ErrorLevel matches the filter, call the protocol
Initialize	gHobList = NULL;
Scan	the configuration table for the HOB list GUID
Assert	if HOB list was not found
Assert	if HOB list pointer is NULL after attempted resolution
Step	1: Initialize global pointers
Step	2: Locate the HOB list
Step	3: Log platform identification string
Step	4: Locate the UBA board-type protocol
No	registration	just locate existing protocol
Step	5: Register the setup configuration data
The	RegisterSetupConfig callback is at offset +0x10 in the protocol
24	bytes
