Author here. It wouldn't particularly surprise me. If I had to guess why other NXP products didn't go with Synopsys, it might be related to the fact that the i.MX8M is intended to be suitable for mobile applications therefore support for LPDDR4 is more important. In fact Synopsys's DDR4 PHY can support both, I believe (IIRC) dynamically, with i.MX8M chips which can be used with either. There are other DDR PHY IP providers (e.g. Cadence) which don't require blobs. Plus these are probably separate business units. I've confirmed the presence of these blobs in i.MX8M BSPs myself, as has Purism, see their blog post. |
