So, summarize that in a short sentence, like "This will be used in the MONAKA
server scheduled for shipment in 2027."

Just strip it to the only significant parts, see below

Device (SMB0)
{
Name (_HID, "FUJI200B") // _HID: Hardware ID
Name (_UID, Zero) // _UID: Unique ID
...
Name (_CRS, ResourceTemplate ()
{
Memory32Fixed (ReadWrite,
0x2A4B0000, // Address Base
0x00010000, // Address Length
)
Interrupt (ResourceConsumer, Level, ActiveHigh, Exclusive, ,, )
{
0x00000159,
}
})
...
}

...

Hmm... Why Device object is called SMB0, are you sure it's the correct one?
