This is based on previous patches, but has been rebased on the latest master and updated for the latest spec. The spec is avaliable at: https://docs.google.com/document/d/1Mh_aiHYxemL0umN3GTTw8vsbmzHZ_nxZXgjgOUzbvc8 This was tested by running Tock on the OpenTitan board. This is based on the original work by: Hongzheng-Li Hou Weiying Myriad-Dreamin v3: - Address Bin's comments on the ePMP implementation v2: - Rebase on the RISC-V tree Alistair Francis (4): target/riscv: Fix the PMP is locked check when using TOR target/riscv: Add the ePMP feature target/riscv/pmp: Remove outdated comment target/riscv: Add ePMP support for the Ibex CPU Hou Weiying (4): target/riscv: Define ePMP mseccfg target/riscv: Add ePMP CSR access functions target/riscv: Implementation of enhanced PMP (ePMP) target/riscv: Add a config option for ePMP target/riscv/cpu.h | 3 + target/riscv/cpu_bits.h | 3 + target/riscv/pmp.h | 14 +++ target/riscv/cpu.c | 11 ++ target/riscv/csr.c | 24 ++++ target/riscv/pmp.c | 228 +++++++++++++++++++++++++++++++++----- target/riscv/trace-events | 3 + 7 files changed, 260 insertions(+), 26 deletions(-)
