From 7aaab96a9b1c37f473f73363ff815eb059a2f823 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Philippe=20Mathieu-Daud=C3=A9?= Date: Mon, 12 Oct 2020 11:57:55 +0200 Subject: target/mips/cpu: Introduce mips_cpu_create_with_clock() helper MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Introduce an helper to create a MIPS CPU and connect it to a reference clock. This helper is not MIPS specific, but so far only MIPS CPUs need it.
