There was a problem hiding this comment.
I think the include mechanism is suboptimal as it increases the compile times and introduces wrong dependencies.
Why not move the get_mstatus_mask() functions as get_mstatus_m_mask()/get_mstatus_mu_mask()/get_mstatus_msu_mask() into riscv_common.h?
This would remove the need of riscv_hart_m_p.h being included in riscv_hart_mu_p.h which in turn is included in riscv_hart_msu_vp.h

This pull request introduces the handling of the VS and FS field, at least from the privilege wrapper side.
This means that if the F or V extension are present, the corresponding mstatus (and lower level views) bits can be set and read.
In the same scope the handling of reading ustatus and sstatus were refactored to represent a more hierarchical approach. The functionality of the mu wrapper now builds on the m wrapper.
