I would like to consider adding a mechanism to indicate that a uclass should be inited (and its devices probed) on startup. This would be used for things which provide essential peripherals, which otherwise would not be visible in the initial driver-model bind process. I am not sure whether this should be: - a flag in the uclass - a flag in the BOARD driver (assuming we have a BOARD uclass soon) - a function call into DM - something else But I think it is justified in the case of PCI, since some systems cannot find all their devices without scanning it. What do you think? Regards, Simon _______________________________________________ U-Boot mailing list [email protected] https://lists.denx.de/listinfo/u-boot
