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?
adapt the naming to make it more accurate future proof.
As for EIP-28, it is also part of EIP-94. EIP-94 is supported by theIs this driver upstream? I didn't find it. Anyhow, thanks for 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.
feedback, I will update with this knowledge in mind.
You can find the driver in the drivers/crypto/amcc directory. It contains
no references to EIP-94. It’s likely that when it was added, it wasn’t
clear that it was a generic IP core.
A while ago, I was looking for information about the PRNGs built into
Rambus crypto accelerators. I found out that all these accelerators are
made up of blocks and have some common components.
EIP-93:
* PE (various IP cores),
* PRNG (EIP-73a),
* Interrupt controller (unnamed?)
EIP-94:
* PE (various IP cores),
* PRNG (EIP-73d),
* TRNG (unnamed?),
* PKA (EIP-28),
* Interrupt Controller (unnamed?).
EIP-97:
* PE (EIP-96)
* AIC (EIP-201),
* PRNG (EIP-73d),
* HIA (EIP-202),
* PP (EIP-206).
EIP-196:
* PE (EIP-96)
* AIC (EIP-201),
* PRNG (EIP-73d),
* HIA (EIP-202),
* PP (EIP-206).
EIP-197:
* PE (EIP-96)
* AIC (EIP-201),
* PRNG (EIP-74),
* HIA (EIP-202),
* PP (EIP-206),
* ICE/OCE (EIP-207),
* Buffers (EIP-208).
