Add an extra partition to the disk image generated for FVP and
Foundation platform (to be used for user data or extra usage). The
partition is created on the hard drive but is not formated.
Speed up running on FVP and Foundation by optimizing model parameters:
- disable options that are already set by default
- disable cache modelling on FVP
- disable secure memory
- disable real time on Foundation (prevents timeout as execution is a
lot slower then on a real system)

We are using gerrit internally. It would be a nightmare of rebases if
we remove it, as it would not match our internal version.
Thanks,

The patch has been accepted and pushed to the master branch of
meta-arm. Thank you for doing this work.
Thanks,
