Hi all:

This patchset introduces LoongArch's built-in dtb support.

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.
