From i.MX 6Solo/6DualLite Applications Processor Reference Manual, Rev. 4, 07/2018
38.4.8.1.1 FIFO allocation to channels
The physical memory is partitioned to 8 segments. For each channel the user has to
define the start address at a segment's boundary using the DMFC_ST_ADDR parameter
DMFC_ST_ADDR is defined below.
I would like to know physical address of DMFC. How do I get it?
Is it defined as EBA0 and EBA1 in CPMEM?

Hi Kazuma
DMFC is internal IPU fifo memory, it has not physical address.
IPU uses DMFC through segments, its parameters
DMFC_FIFO_SIZE, DMFC_ST_ADDR are described in
sect.37.4.8.1.1 FIFO allocation to channels i.MX6DQ Reference Manual

>Is it defined as EBA0 and EBA1 in CPMEM?
no.
