Difference between ArmVirtPkg/ArmVirtQemu.dsc and ArmVirtPkg/ArmVirtQemuKernel.dsc

[weigao-bosch]

Hello,
Could someone give me some hint about the difference between ArmVirtPkg/ArmVirtQemu.dsc and ArmVirtPkg/ArmVirtQemuKernel.dsc

I'm playing arm-trusted-firmware according to instructions at https://github.com/ARM-software/arm-trusted-firmware/blob/master/docs/plat/qemu.rst

It suggested to use ArmVirtPkg/ArmVirtQemuKernel.dsc as below

git clone https://github.com/tianocore/edk2.git
cd edk2
git submodule update --init
make -C BaseTools
source edksetup.sh
export GCC5_AARCH64_PREFIX=aarch64-linux-gnu-
build -a AARCH64 -t GCC5 -p ArmVirtPkg/ArmVirtQemuKernel.dsc

However, I found another file ArmVirtPkg/ArmVirtQemu.dsc in the repo and tried both.
I couldn't manage to make the system runing with ArmVirtPkg/ArmVirtQemu.dsc , could someone give me some hint of the difference?
Thanks
