I assumed this would be in Mainline u-boot, but apparently not. On closer inspection of the internal ST-Ericsson u-boot, this functionality appears to be provided by patches which currently exist as delta. So in essence, the bootloader you use will have to be patched in a similar way for you to retrieve information surrounding bootloader boot times. And there was me thinking it was magic. ;) -- Lee Jones Linaro ST-Ericsson 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@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
