Hey Simon,

Incidentally i got acces to a Nyan big and wanted to start testing
u-boot on it. Unfortunately putting a uImage in a vboot signed blob to
chainload it from the primary bootloader like on the exynos based
chromebooks seemed not to work.

Do you have any good pointers how to use u-boot on nyan? (Ideally
without having to re-flash coreboot, as i would like to create images
people can easily test on a vanilla chromebook)
