Currently, the installation instructions are for installing SST-core and SST-elements version 11.0.0. This change updates instructions to the current SST-core and SST-element version, 11.1.0. This change also reflects that manually downloading the `bbl-busybox-boot-exit` is no longer necessary as the example gem5 config will download automatically.

Installing SST
The links to download SST source code are available here
[http://sst-simulator.org/SSTPages/SSTMainDownloads/].
This guide is using the most recent SST version (11.0.0) as of September 2021.
The following guide assumes $SST_CORE_HOME as the location where SST will be
installed.
SST-Core
Downloading the SST-Core Source Code
wget https://github.com/sstsimulator/sst-core/releases/download/v11.1.0_Final/sstcore-11.1.0.tar.gz
tar xf sstcore-11.1.0.tar.gz
Installing SST-Core
cd sstcore-11.1.0
./configure --prefix=$SST_CORE_HOME --with-python=/usr/bin/python3-config \
--disable-mpi # optional, used when MPI is not available.
make all -j$(nproc)
make install
Update PATH,
export PATH=$SST_CORE_HOME/bin:$PATH
SST-Elements
Downloading the SST-Elements Source Code
wget https://github.com/sstsimulator/sst-elements/releases/download/v11.1.0_Final/sstelements-11.1.0.tar.gz
tar xf sstelements-11.1.0.tar.gz
Installing SST-Elements
cd sst-elements-library-11.1.0
./configure --prefix=$SST_CORE_HOME --with-python=/usr/bin/python3-config \
--with-sst-core=$SST_CORE_HOME
make all -j$(nproc)
make install
Adding PKG_CONFIG_PATH to .bashrc (so pkg-config can find SST .pc file),
echo "export PKG_CONFIG_PATH=$PKG_CONFIG_PATH:$SST_CORE_HOME/lib/pkgconfig/" >> ~/.bashrc
Building gem5 library
At the root of gem5 folder,
scons build/RISCV/libgem5_opt.so -j $(nproc) --without-tcmalloc
Compiling the SST integration
At the root of gem5 folder,
cd ext/sst
make
Running an example simulation
Running the simulation
sst --add-lib-path=./ sst/example.py
The example SST system configuration will instantiate the gem5 system
as specified in the gem5 system configuration located at
gem5/configs/example/sst/riscv_fs.py. This configuration will download
the bbl-busybox-boot-exit resource, which contains an m5 binary, and
m5 exit will be called upon the booting process reaching the early userspace.
More information about building a bootloader containing a Linux Kernel and a
customized workload is available at
[https://gem5.googlesource.com/public/gem5-resources/+/refs/heads/develop/src/riscv-boot-exit-nodisk/].
