Editing Flash-Bridge

Some structures for SCEI USB-SATA Bridge:
<source lang="C">
struct Firmware								// Starts at offset 0x2000
{
	struct Info
	{
		unsigned int Unk1[32];					// Looks as encrypted array or maybe decryption key?
		unsigned int Size;					// 0x14834 - size of Unk2 and Data that goes below
		unsigned int Unk2;					// 0x82
		unsigned char Data[0x14830]				// Encrypted firmware data?
	}
	unsigned int Reserved;						// Reserved/Alignment?
	unsigned int Crc32;						// CRC32 of Info structure
}
