48 The original chipset, no longer made.
49 This extremely rare unit
50 was not very fast, lacked a RNG, and had a number of other bugs.
52 A faster and fixed version of the original, with a random number
53 unit and large number engine added.
55 A BCM5805 without public key engine or random number generator.
57 A slower version of the BCM5805.
59 Faster version of Bluesteel 5601.
61 64 bit version of the chip, and significantly more advanced.
63 Faster version of the BCM5820.
65 Faster version of the BCM5820.
67 A BCM5822 with AES capability.
72 driver registers itself to accelerate DES, Triple-DES, MD5-HMAC,
