PCI: designware: Explain why we don't program ATU for some platforms Some platforms don't support ATU, e.g., pci-keystone.c. These platforms use their own address translation component rather than ATU, and they provide the rd_other_conf and wr_other_conf methods to program the translation component and perform the access. Add a comment to explain why we don't program the ATU for these platforms. [bhelgaas: changelog] Signed-off-by: Jisheng Zhang <jszhang@marvell.com> Signed-off-by: Bjorn Helgaas <bhelgaas@google.com>
