The cover-letter[0] for the series does mention that the changes are for
DMASS0_PKTDMA_RINGRT and DMASS0_PKTDMA_TCHANRT with the current and
correct region size.
It also mentions the section and the Table from where we can check them.
{*** section for Main Memory Map (Table 2-1)}

It was same check across all platform so added in cover letter.
But I will add that in each patch.
Thanks,
Jayesh
