Ok, cool.

In the sense that some vendor might require just a little bit different
handling or maybe wants to read some vendor-specific registers in
addition to the architectural ones.

Then we'll start adding vendor-specific hacks to that generic driver.
And therefore the question how fast and how ugly such hacks would
become.

I guess we'll worry about that when we get there...

So Brijesh, if you only need generic, architectural functionality,
please call it arm64_edac or so and let's add it so that other arm64
vendors can use it too.

Thanks.
