Subject: [PATCH v3 8/8] target/riscv: Add ePMP support for the Ibex CPU
Date: Tue, 13 Apr 2021 12:43:08 +1000	[thread overview]
Message-ID: <01a14ca289ed6ceb87fdaae61e4689937244518f.1618281655.git.alistair.francis@wdc.com> (raw)
In-Reply-To: <cover.1618281655.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.
