That the newer u-boot can aware extra on Kilauea is really as you said. But I think I/we need to consider some other requirements for 405EX, such as only using one image for convenient on embedded system, and u-boot don't pass dtb for kernel since it will be isolated with one customer software layer. And actually to support old U-boot compatibility is original *goal* of implementing cuImage in kernel as we know. Right? As Documentation/powerpc/bootwrapper.txt I think the kernel should support more image variant to satisfy different requirement. Sometimes that is also beyond we can discuss here. > Are you using it for some other board derived from 405EX that doesn't have > an FDT aware U-Boot? > Yes, this is really another factor. Anyway thinks your comments.
