I have an armplatbld.sh script that goes through and tries to build as many of the Arm (AARCH64 and ARM) platforms in edk2-platforms as possible. I'm think this used to work for these, but I'm getting some errors now. I'm using edk2-platforms 46686eeb7e78efe603badd86f13777d9fb070fb8 and edk2 e2ac68a23b4954d5c0399913a1df3dd9fd90315d.
