[PATCH] spidernet: read firmware from the OF device tree
request_firmware() is sometimes problematic, especially in initramfs, reading the firmware from Open Firmware is much preferrable. We still try to get the firmware from the file system first, in order to support old SLOF releases and to allow updates of the spidernet firmware without reflashing the system.
