13 The UDMA-P is intended to perform similar (but significantly upgraded)
14 functions as the packet-oriented DMA used on previous SoC devices. The UDMA-P
16 The UDMA-P architecture facilitates the segmentation and reassembly of SoC DMA
27 on the Rx PSI-L interface.
29 The UDMA-P also supports acting as both a UTC and UDMA-C for its internal
