Subject: [PATCH v1 8/8] target/riscv: Add ePMP support for the Ibex CPU
Date: Fri,  2 Apr 2021 08:48:31 -0400	[thread overview]
Message-ID: <169e1a3c65731c9ee5be4d0c394d53d0d8b2655d.1617367533.git.alistair.francis@wdc.com> (raw)
In-Reply-To: <cover.1617367533.git.alistair.francis@wdc.com>

The physical Ibex CPU has ePMP support and it's enabled for the
OpenTitan machine so let's enable ePMP support for the Ibex CPU in QEMU.
