Getting U-Boot FIT for Xen - Robbie VanVossen & Paul Skentzos, DornerWorks

The Flattened Image Tree (FIT) image is a single formatted binary that supports multiple images and configurations that U-Boot understands. This format allows U-boot to perform integrity checks on the images, load a single image, and select from multiple configurations. The FIT format originally only allowed for loading a single kernel, a single ramdisk, and a single Flattened Device Tree (FDT) from the items in the image. But Xen requires two kernels: one for the Xen hypervisor and one for the Dom0 OS. So until now Xen users could not take advantage of the multiple benefits of the FIT image. Robert VanVossen will give an overview of the modifications DornerWorks made to U-Boot, allowing the FIT format to support loading generic images. He will further explain the benefits this brings to the Xen community and provide some examples of generating and using a FIT image to boot a Xen system.
