See	sub_A24 for the per-controller enumeration logic
and	sub_E2C for the per-controller iteration.
This	function appears to be the outermost dispatcher.
r14	- capacity GB integer part
rax	__int64 v9; // rdi - status
r15	- loop index
rsi	- offset into handle buffer
rax	- status (OpenProtocol for ATA)
rdx	- line number for assert
rax	- status
r9	- swap index
eax	- loop counter for model swap
rcx	__int64 v20; // r8
dl	- temp for byte swap
rax	- trim loop
rcx	- capacity sectors
rcx	- capacity in bytes
rbx	- capacity fractional GB
Allocate	pool for model string buffer (256 bytes)
Allocate	pool for capacity string buffer (256 bytes)
Open	the ATA Pass Thru protocol on the controller handle
to	get the list of available ports/devices
Check	if port is enabled (bit 3 of attributes)
Open	ATA protocol interface on this port
Check	if device matches expected GUID (unk_2CC0)
Get	device type info (HDD vs SSD detection)
Allocate	IDENTIFY data buffer (512 bytes)
Zero	the IDENTIFY buffer
Send	IDENTIFY DEVICE command via ATA Pass Thru
Parse	model name from ATA IDENTIFY data (byte-swapped)
ATA	model name is in words 27-46 (54 bytes), byte-swapped
Trim	trailing spaces from model name
Format	model name as ASCII string
Calculate	capacity
Device	does not support LBA - use ATAPI fallback
Convert	sectors to GB (sector size = 512 bytes = << 9)
total	bytes
GB	integer part
GB	fractional part (1 decimal)
Categorize	as SSD or HDD
SSD	count
SSD	total capacity
Free	IDENTIFY buffer
ASSERT	on failure
rax	__int64 v10; // rbx - status
rcx	__int64 v18; // rax - status from sub_A24
Locate	all handles supporting ATA Pass Thru protocol
ByProtocol	&unk_2D00, // ATA Pass Thru GUID
Open	ATA Pass Thru protocol on this handle
Open	Block IO protocol to get device topology info
Get	device location (SATA port, bus, device, function)
Reset	the ATA controller port
Debug	print: SATA controller location
Enumerate	devices on this controller
Accumulate	HDD count
Accumulate	HDD capacity
Accumulate	SSD count
Accumulate	SSD capacity

rax	va_list va; // [rsp+48h] [rbp+10h] BYREF
Wraps	DebugPrint or similar UEFI debug output function
Standard	UEFI ASSERT implementation:
Registers	sub_10C0 as a ReadyToBoot callback
Uses	gBS->CreateEventEx(EVT_NOTIFY_SIGNAL, TPL_CALLBACK, sub_10C0, ...)
or	gBS->RegisterProtocolNotify(...)
Initialize	UEFI libraries:
Wraps	gBS->SetMem() or BaseMemoryLib SetMem()
Converts	ASCII string to uppercase
