I'm not entirely sure what you mean by this, as I have Snowball booting as a Device Tree only platform: http://www.spinics.net/lists/kernel/msg1590759.html The Machine ID should be all F's for DT I think. > Unfortunately I can't get to my home network right now to double-check > boot logs to see if this has changed behavior recently, I'll have to > do that later today.

I just changed SNOWBALL's machine ID to 9999 and it still boots just fine with DT (ATAGs boot hangs). So what did you do? Can you send me a patch of what you did, so I might reproduce your build please? -- Lee Jones Linaro STMicroelectronics Landing Team Lead Linaro.org │ Open source software for ARM SoCs Follow Linaro: Facebook | Twitter | Blog -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
