compile and run

The same with official qemu releases. Please refer to official documents to install necessary dependent packages. One example session:

cd <qemu-source-path>/
mkdir ./build
cd ./build
../configure --target-list=mipsel-softmmu,mips64el-softmmu --disable-werror
make

TODO

Previously it is mainly written for internal usages so there are not enough documents yet. Information for related boards/pmons/kernels will be provided later.
