Forward	declarations
EFI_STATUS	EFIAPI
Copies	Length bytes from Source to Destination.
If	Source < Destination and ranges overlap, copies backward.
Otherwise	uses dword-aligned copy then residual.
Uses	InternalSetMem32-style write in a counted loop
Saves	callee-saved registers, stack pointer, and return address
Prepare	return address
Jump	to continuation
If	ModeFlags != 0 (x64): creates PML4[0..511] each pointing to
a	PDP table with 512 PDEs mapping 0x200000 pages.
If	ModeFlags == 0: creates 512 PML4 entries with 0x40000000 pages.
Unused	entries zeroed.
should	not return
First	call: set up page tables and long mode
Installs	the Capsule PPI with gEfiPeiCapsulePpiGuid
Read	CMOS index 0x4A
Normal	range - small value
Server	return EFI_ACCESS_DENIED; // Other known
Overlap	check against L"CapsuleUpdateData" storage
Returns	length of L"CapsuleUpdateData" (15 characters)
Copies	"CapsuleUpdateData\0" to destination
Converts	Value to decimal string, stores in Buffer
Full	format string parser with number conversion
Found	the capsule PE image
Locate	PE32 section, get entry point
Walk	the HOB list, collect EFI_RESOURCE_MEMORY resources.
Returns	the resource with largest descriptor.
Enumerate	all "CapsuleUpdateData" variable instances
Variable	is gEfiCapsuleVendorGuid + L"CapsuleUpdateData" Name
Allocate	storage for capsule variable list
Validate	signature = 0x50637343 ("Csc")
Read	capsule sizes and counts
Allocate	pages for coalesced data
Copy	segment by segment
Call	CapsuleDataCoalesce to build final capsule
Check	Address + Size does not overflow
Verify	range falls within one of the memory resources
Validate	data block
First	capsule header
Check	flags: must have CAPSULE_FLAGS_PERSIST_ACROSS_RESET
but	not INITIATE_RESET or some other exclude bit
Continuation	pointer
Given	a capsule descriptor chain at SourceEnd, walks
continuation	entries to compute a safe relocation
destination	that doesn't overlap source data.
Walks	all descriptors, copies data blocks
Handles	overlap via CapsuleRelocateOverlap
Walk	descriptors, sum lengths, find capsule header
If	the first data block has signature 0x54534554 ("TEST")
followed	by sequence 0,1,2,..., then it passes as test pattern.
Chains	all valid capsule descriptors together
Check	platform capabilities
Determine	if long mode is available
Parse	capsule buffer layout
Validate	capsule range against system memory
Populate	descriptor context
StackBase	VariableEntries[3] = CapsuleBuffer + 3;
Reserved	param
CapsuleStart	VariableEntries[10] = MemoryResources; // Memory descriptors
SGDT	for GDTR save
TE	image
Already	notified - this is expected on repeat calls
Install	the Capsule PPI
