I think we shouldn't consider there to be an SDHCI order problem. Relying on block devices to appear with a specific name is probably something we shouldn't do. The fact it happened with SDHCI is pretty unique; it doesn't for USB-attached devices, removable SDHCI devices, etc. Instead, you can use partition or filesystem UUIDs to name devices. I boot with root=PARTUUID=xxxx these days, and hence never have to adjust my command-line depending on the SDHCI probe ordering differences, and it's work just fine for USB or other storage too. -- To unsubscribe from this list: send the line "unsubscribe linux-tegra" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html
