Hi, I''ve tried several different approaches to debootstrap a working rootfs for with a Cortex A15 model ( FastModels ) and Xen but still face some issues. Some information on my setup. For a Dom0 kernel I''m using the latest version from git://github.com/torvalds/linux.git, I attached my config as it might be of some use for others. I''m using the latest Xen unstable

This series of patches makes Xen pass a (somewhat) valid device tree to dom0. The device tree for dom0 is the same as the one supplied to Xen except the memory and chosen nodes are adjusted appropriately. We don''t yet make use of the device tree to map MMIO regions or setup interrupts for the guest and we still include the UART used for Xen''s console. Note that loading Linux
