`DDRPhyWrite`

Write DDR40 phy registers

DDRPhyWrite

Shortest form: ddrpw.

Write a DDR40 PHY register of an external memory interface: DDRPhyWrite ci<n>[,…] Addr=<address> Data=<value>. Changes PHY configuration. These commands are for switch chips with external DDR3 memory behind DDR40 PHYs and “CI” memory-interface ports. A Trident 3 has neither, so the interface argument (ci0, ci0,ci1 …) is not a valid port list there and the command only prints its usage.
