Having #size-cells == 0 in a node indicates that things under the node aren't directly accessible, and therefore we shouldn't try to translate addresses for devices under the node into CPU physical addresses. Some drivers, such as the nvram driver for powermacs, rely on of_address_to_resource failing if they are called for a node representing a device whose resources aren't directly accessible by the CPU. These drivers were broken by commit fd6e9d39, resulting in the "Lombard" powerbook hanging early in the boot process. Signed-off-by: Paul Mackerras --- Reading git-diff-tree failed
