AMD XHCI

The AMD XHCI controller in Hudson chip seems to be IP Core of Renesas uPD720200/200A. It looks the firmware consists of multi parts:

XHCI firmware layout header 0xe bytes
Offset Size in bytes What
0x0000 2 Signature 0x55aa
0x0002 2 Offset to the BCD (type0?)
0x0004 2 BCD size
0x0006 2 Offset to Main FW (type1?)
0x0008 2 Main FW size
0x000a 2 Offset to the ACD (type2?)
0x000c 2 Offset to the ACD
Main FW
Offset Size in bytes What
0x0000 2 Firmware version - 0x3032 means 3.0.3.2
0x0002 - Firmware data, most likely V850E1 controller

The firmware in blobs repository is 3.0.3.2, quite common version 3.0.3.4.0.8 found on the internet matches well 0xcf0 bytes. It is not know where the 0.8 subversion is stored.
