From dbc3d8f0ef19563a89aea266e032acbab549f7fe Mon Sep 17 00:00:00 2001 From: Anup Patel Date: Thu, 28 Apr 2022 18:59:14 +0530 Subject: lib: sbi: Remove MCOUNTINHIBT hart feature If a hart implements privileged spec v1.11 (or higher) then we can safely assume that mcountinhibit CSR is present and we don't need MCOUNTINHIBT as a hart feature.
