This firmware file is the RTOS for the Spacemit K1x realtime CPU.
The Spacemit firmware is based on the Thread Operating System RTOS,
see https://www.rt-thread.io/ for an explanation. New esos.elf files
can be downloaded from the Spacemit repo hosted on a Chinese
GIT site, see https://gitee.com/spacemit-buildroot/buildroot-ext.
One of the branches there also has a license file, reproduced here:
