There is only one board in the mainline kernel, but Paul Cercueil and me did
maintain a kernel for the Dingoo A320 for a while which is also JZ4740-
based. Also, a lot of the JZ4740 drivers can be used as-is or with small
adaptations on later SoC generations. For example, we're using a slightly
modified version of this watchdog driver on the JZ4770-based GCW Zero.
