The SiFive Premier P550 [1] is a new development board from SiFive that is based on the ESWIN EIC7700X SoC. The platform is interesting to the seL4 community as it implements the RISC-V hypervisor extension meaning we now have real hardware to evaluate RISC-V hypervisor changes to seL4. It also implements the Sscofpmf extension and so we'll be able to get more experiment with proper profiling on RISC-V. Unfortunately, it seems we still do not have proper ASID suppor according to [2]. The board comes in two configurations, 16GB and 32GB of memory. This adds support for the 16GB model. The DTS comes from SiFive's fork of Linux [3]. No modifications were made, any extra things are in the overlay.
