getting started with armv8-a

Hi,

I am getting started with armv8-a and I need some help.

I am trying to understand how cache memories work and I am looking specifically at this code:

https://github.com/rsta2/circle/blob/master/boot/armstub/armstub8.S

There is a reference to register S3_1_C11_C0_2 which I don't see mentioned in the whole ARMARM document. I am doing a text search on the PDF document so I may have missed it.

Does anyone know where documentation about it can be found?

Thanks
