Hi Larry,

Currently, I can build "zImage" for Sequoia using the powerpc architecture, and load it using U-Boot without a separate FDT binary. Is this the best way to run a Linux from the powerpc tree?
Sorry, I don't understand what you're asking.
There are two way to boot a Linux image from arch/powerpc.
- build a uImage and get u-boot to pass a device tree blob (if your u-boot
had device tree support) 2) build a cuImage which wraps the device tree in the kernel image.
Correct. Personally I prefer 1), since it makes the Linux ports easier. No bootwrapper is needed in this case. And all the "infrastructure" for fdt enabled U-Boot images for 4xx is available. Please take a look at sequoia.c/.h and search for CONFIG_OF_LIBFDT.
Just let me know if this is not clear or if you have additional questions.
Best regards, Stefan
