[PATCH v2 0/5] OpenSBI hart protection abstraction

[Anup Patel]

Currently, PMP and ePMP are the only hart protection mechanisms
available in OpenSBI but new protection mechanisms (such as Smmpt)
will be added in the near future. This series adds hart protection
abstraction and related APIs for allowing multiple hart protection
mechanisms.

These patches can also found in hart_protection_v2 branch at:
https://github.com/avpatel/opensbi.git

Changes since v1:
 - Added documentation for function parameters in PATCH2
 - Dropped return value of sbi_hart_protection_unregister() in PATCH2
 - Register oldpmp hart protection only when Smepmp is not available
   in PATCH3
