Qemu Loongson

This is a customized qemu verion for loongson processors based v2.12.92. Currently it supports these loongson boards:

fulong2e Fulong 2e mini pc

ls1a mips ls1a platform

ls1b mips ls1b platform

ls1c mips ls1c platform

ls232 mips ls232 platform

ls2f1a mips ls2f1a platform

ls2h mips ls2h platform

ls2k mips ls2k platform

ls3a mips ls3a platform

ls3a2h mips ls3a2h platform (still have some issues left)

ls3a7a mips ls3a7a platform

compile and run

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

cd /

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.
