Enable CONFIG_SPL_DM and enable the driver model for serial by defining an appropriate device in the board file for da850-lcdk.
This breaks booting from MMC on omapl138_lcdk. You didn't add a U_BOOT_DEVICE for the mmc node.
Thanks, Faiz
Just letting you know I haven't forgotten about this. I finally got some time to work on it this week, but it turned out to be non-trivial, as for some reason the set_cmd mmc callback is not being properly assigned in SPL with driver-model and I couldn't find out why so far. Next week I'm at ELCE, but I'll be back at it on Thursday. I'm not sure if you want to revert the offending patch for now or this can wait for another week?
Best regards, Bartosz Golaszewski
I've been working on this some more this week and noticed that in SPL for some reason the bind function of the mmc driver is not called (despite the driver being probed fine), but so far I've been unable to figure out why exactly. This is the reason for the failure as the mmc is not properly setup but the mmc core thinks it is and tries using it.
I've tried both using a U_BOOT_DEVICE() defined in the board file or adding the mmc node to arch/arm/dts/da850-lcdk-u-boot.dtsi.
Adam: you know davinci's SPL pretty well - do you have any suggestions?
