What is changed?
- Added a new mps3 board an555 for the soc corstone310.
The qualifier to build/run application with board mps3/an555 is
`mps3/corstone310/an555` for secure and
`mps3/corstone310/an555/ns` for non-secure.
- Added FVP variant to enable FVP testing with corstone310
and it uses the ARM FVP `FVP_Corstone_SSE-310`.
The qualifier to build/run application with FVP is
`mps3/corstone310/an555fvp` for secure and
`mps3/corstone310/an555fvp/ns` for non-secure.
Why do we need this change?
- This enables FVP support and testing for corstone310.
- A separate FVP variant was added for AN555 because, the TFM board
used for non-secure variant differs for FPGA and FVP.
TFM board `arm/mps3/corstone310/an555` should be used when testing
AN555 with FVP and `arm/mps3/corstone310/fvp` should be used when
testing with AN555 FPGA.
