[Qemu-ppc] [PULL 09/12] cuda: don't call cuda_update() when writing to A

From: David Gibson
Subject: [Qemu-ppc] [PULL 09/12] cuda: don't call cuda_update() when writing to ACR register
Date: Mon, 12 Feb 2018 14:40:51 +1100

From: Mark Cave-Ayland <address@hidden>

The wire protocol for reading data to/from the VIA is triggered by changing
inputs on port B rather than changing the timer configuration via the ACR.
