In commit e6a6928c "of/fdt: Convert FDT functions to use libfdt", the kernel stopped supporting old flat device tree formats. The minimum supported version is now 0x10. There was a checking function added, early_init_dt_verify(), but it's not called on powerpc. The result is, if you boot with an old flat device tree, the kernel will fail to parse it correctly, think you have no memory etc. and hilarity ensues. We can't really fix it, but we can at least catch the fact that the device tree is in an unsupported format and panic(). We can't call BUG(), it's too early. Signed-off-by:
