Subject: [PATCH v3 0/8]  RISC-V: Add support for ePMP v0.9.1
Date: Tue, 13 Apr 2021 12:41:14 +1000	[thread overview]
Message-ID: <cover.1618281655.git.alistair.francis@wdc.com> (raw)

This series adds support for ePMP v0.9.1 to the QEMU RISC-V target.

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.

 Hongzheng-Li <Ethan.Lee.QNL@gmail.com>
 Hou Weiying <weiying_hou@outlook.com>
 Myriad-Dreamin <camiyoru@gmail.com>

v3:
 - Address Bin's comments on the ePMP implementation
v2:
 - Rebase on the RISC-V tree

  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  target/riscv/pmp: Remove outdated comment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):
