From 98bd8b73c0e2c545ef3f100f1754c7fff47ad57a Mon Sep 17 00:00:00 2001 From: Benjamin Herrenschmidt Date: Thu, 31 Oct 2019 19:43:58 +1100 Subject: [PATCH] control: Reduce pipeline depth to 1 To match our one stage execute. This might change back if we end up adding 2 stages to match the LSU, but in that case we'll want forwards as well.
