The Level 2 Cache Controller also -acts as directory-based coherency manager. -All the properties in ePAPR/DeviceTree specification applies for this platform - -Required Properties: --------------------- -- compatible: Should be "sifive,fu540-c000-ccache" and "cache" - -- cache-block-size: Specifies the block size in bytes of the cache. - Should be 64 - -- cache-level: Should be set to 2 for a level 2 cache - -- cache-sets: Specifies the number of associativity sets of the cache. - Should be 1024 - -- cache-size: Specifies the size in bytes of the cache. Should be 2097152 - -- cache-unified: Specifies the cache is a unified cache - -- interrupts: Must contain 3 entries (DirError, DataError and DataFail signals) - -- reg: Physical base address and size of L2 cache controller registers map - -Optional Properties: --------------------- -- next-level-cache: phandle to the next level cache if present. - -- memory-region: reference to the reserved-memory for the L2 Loosely Integrated - Memory region.
