Guenter Roeck de164a7f19 nios2: Only use built-in devicetree blob if configured to do so ... Starting with commit 7b937cc243 ("of: Create of_root if no dtb provided by firmware"), attempts to boot nios2 images with an external devicetree blob result in a crash. Kernel panic - not syncing: early_init_dt_alloc_memory_arch: Failed to allocate 72 bytes align=0x40 For nios2, a built-in devicetree blob always overrides devicetree blobs provided by ROMMON/BIOS. This includes the new dummy devicetree blob. Result is that the dummy devicetree blob is used even if an external devicetree blob is provided. Since the dummy devicetree blob does not include any memory information, memory allocations fail, resulting in the crash. To fix the problem, only use the built-in devicetree blob if CONFIG_NIOS2_DTB_SOURCE_BOOL is enabled.
