As we know, the Loongson-2K family supports DT. Inevitably, some systems do not provide a useful device tree to the kernel at boot time. Chasing around bootloaders for these systems is a headache, so we just keep a device tree table in the kernel, keyed by the dts filename, that contains the relevant DTBs. Thanks.
