This interrupt mapping is specific to the EIP-150. The EIP-201 is also 
integrated
into other accelerators, such as the EIP-97, EIP-196, and EIP-197, and the
interrupt mapping is likely different there. Maybe it would be better to use
eip150 name instead of eip201?

As for EIP-28, it is also part of EIP-94. EIP-94 is supported by the 
amcc driver.
EIP-94 consists of four components:
* crypto accelerator (unnamed?),
* PRNG (EIP-73d),
* TRNG (unnamed?),
* PKA (EIP-28).
Only the first three components are supported by the amcc driver.


Best regards,
Aleksander
