10 UniPhier ARM 32-bit SoCs are integrated with a full-custom outer cache
11 controller system. All of them have a level 2 cache controller, and some
12 have a level 3 cache controller as well.

8 title: Andestech AX45MP L2 Cache Controller
11 - Lad Prabhakar <prabhakar.mahadev-[email protected]>
14 A level-2 cache (L2C) is used to improve the system performance by providing
15 a large amount of cache line entries and reasonable access delays. The L2C
16 is shared between cores, and a non-inclusive non-exclusive policy is used.

10 - Joshua Yeong <[email protected]>
13 StarFive's StarLink Cache Controller manages the L3 cache shared between
14 clusters of CPU cores. The cache driver enables RISC-V non-standard cache
15 management as an alternative to instructions in the RISC-V Zicbom extension.
