Doing a design that will be closely related to the Sabrelite, but a bit unsecure about the DDR3 solution. I would like all 4 chips to be on the primary side, to ease production, and would think that flyby topology would be best. Also I need the possibility to support the Solo too so the initial plan is to place the lower 2x16 bits at the end of the chain.
1. Does the concept seem fine?
2. If using fly-by are there any DDR3 register changes required compared to the sabrelite? I would really like to be able to boot up a board with the sabrelite uboot. So I have a known working good config. Haven't dove into the details here yet though.
