The RD-V1 quad-chip platform consists of four chips connected over cache coherent interconnect. Each chip on the platform includes four single- thread CPUS. Each of the CPUs include 64KB L1 Data cache, 64KB L1 Instruction cache and 1MB L2 cache. The platform also includes a system level cache of 16MB per chip. Add PPTT table for RD-V1 quad-chip platform with this information.
