14 | * MMU functions for the Intel XScale3 Core (XSC3). The XSC3 core is |
15 | * an extension to Intel's original XScale core that adds the following | |
23bdf86a LB |
16 | * features: |
17 | * | |
18 | * - ARMv6 Supersections | |
19 | * - Low Locality Reference pages (replaces mini-cache) | |
20 | * - 36-bit addressing | |
21 | * - L2 cache | |
850b4293 | 22 | * - Cache coherency if chipset supports it |
23bdf86a | 23 | * |
850b4293 | 24 | * Based on original XScale code by Nicolas Pitre. |
