This is a small UEFI application that allows trusted code to create a valid EFI_LOADED_IMAGE_PROTOCOL instance that can be used to transfer control to an arbitrary trusted entry point.

You need a working EDK II build environment.

On Linux, you can create a working EDK II build environment with the following commands:

git clone https://github.com/tianocore/edk2.git
cd edk2
. edksetup.sh
make -C BaseTools/Source/C
cd ..

Clone this repository within your existing EDK II build environment, then build the ProxyLoaderPkg package.

On Linux, you can build with the following commands:

cd edk2
. edksetup.sh
git clone https://github.com/ipxe/ProxyLoaderPkg.git
build -a X64 -t GCC5 -p ProxyLoaderPkg/ProxyLoaderPkg.dsc
