Hello Simon,

I have had a look why the Wandboard cannot be switched to using the driver.

We have one SPL and one u-boot.img for different boards. In function board_init() in the board file board/wandboard/wandboard.c the actual board is determined.

If we enable CONFIG_OF_CONTROL we can specify only one device tree in CONFIG_DEFAULT_DEVICE_TREE.

What is the idea for one image handling multiple devices having different device trees?

Could we specify a list of multiple device trees and use board_init() or board_init_spl() to select the relevant tree?

Probably in SPL we would need only a reduced tree applicable to all Wandboards.

Best regards

Heinrich
