This area will be used for allocating virtio rings and buffers. The common node allows the DSP Memory Protection and Address Extension (MPAX) module to be configured uniformly across all the DSP processors. The reserved memory node and all the user DSP nodes are also marked okay to enable the DSPs on the 66AK2K EVM board.
