Hello,
New format for U-boot images has been on the list few times already. There were different ideas and features discussed but no final conclusion has been made.
I have a request for a new feature. I think we need image-format plug-ins. That is, we need a way for a plug-in to register itself with the main format processing code. When the processing code sees a blob that it doesn't understand, it calls the plug-in to handle it.
This would be a handy way to handle stuff like the QE firmware binary blob format (see the thread titled "[PATCH] 85xx: add ability to upload QE firmware"). The format of the QE firmware blob has already been decided, so all I would need from the multi-image format is:
1) A way to package my blob. 2) A way to pass the address of the blob to the QE code
For option #2, setting an environment variable would be the easiest. To do that, the QE code could register a call-back that says, "If you see a QE firmware blob, call this function and pass the address of the blob".
