From 2c20e75b929a3c68545e40b200fe3710cc9e012f Mon Sep 17 00:00:00 2001 From: Peter Maydell Date: Thu, 4 Feb 2021 16:30:54 +0000 Subject: hw/misc/mps2-fpgaio: Make number of LEDs configurable by board MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The MPS2 board has 2 LEDs, but the MPS3 board has 10 LEDs. The FPGAIO device is similar on both sets of boards, but the LED0 register has correspondingly more bits that have an effect. Add a device property for number of LEDs.
