Kurt,

At this point it doesn't look like there will likely be a standardized method of doing this, at least not anytime on the horizon. We spent a lot of effort on this and had several draft versions but never reached concensus.

The issue was that there are too many different architectures out there and to make a single implementation that was robust enough to be reliable and not risk leaving a product doorstopped with nothing other than boot code made the process a bit cumbersome for some.

Ultimately what happened was that everyone adopted their own manufacturer-specific way of doing it and as a result interest was lost by most involved with it as they then had their own solution.

Firmware uploads are probably best left being a manufacturer-specific implementation that way there isn't the risk of someones bad implementation on the controller side erasing the flash and leaving a product stuck in boot without completing the upgrade process.
