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.

+* 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.
