* may not actually work if u-boot didn't supply one). If
* LOADER_NET_SUPPORT is defined the next item will be a network
* interface. Again it may not actually work at the u-boot level.
*
* The original logic was to always use a disk if it could be
* successfully opened, otherwise use the network interface. Now that
* logic is amended to first check whether the u-boot environment
* contains a loaderdev variable which tells us which device to use. If
* it does, we use it and skip the original (second) loop which "probes"
* for a device. We still loop over the devsw just in case it ever gets
* expanded to hold more than 2 devices (but then unit numbers, which
* don't currently exist, may come into play). If the device named by
* loaderdev isn't found, fall back using to the old "probe" loop.
*
* The original probe loop still effectively behaves as it always has:
* the first usable disk device is choosen, and a network device is used
* only if no disk device is found. The logic has been reworked so that
* it examines (and thus lists) every potential device along the way
* instead of breaking out of the loop when the first device is found.
