A new cross-compilation target that has extensions that DPDK uses and
QEMU supports. Initially, this is just the Zbc extension for hardware
crc support.

@@ -110,6 +110,11 @@ Currently the following targets are supported:
* SiFive U740 SoC: ``config/riscv/riscv64_sifive_u740_linux_gcc``
+* QEMU: ``config/riscv/riscv64_qemu_linux_gcc``
+
+ * A target with all the extensions that QEMU supports that DPDK has a use for
+ (currently ``rv64gc_zbc``). Requires QEMU version 7.0.0 or newer.

To add a new target support, ``config/riscv/meson.build`` has to be modified by
adding a new vendor/architecture id and a corresponding cross-file has to be
added to ``config/riscv`` directory.
