[PATCH v3 1/3] hw/block/m25p80: Fix Numonyx NVCFG DIO and QIO bit polari


From: Joe Komlodi
Subject: [PATCH v3 1/3] hw/block/m25p80: Fix Numonyx NVCFG DIO and QIO bit polarity
Date: Thu, 5 Nov 2020 17:32:56 -0800

QIO and DIO modes should be enabled when the bits in NVCFG are set to 0.
This matches the behavior of the other bits in the NVCFG register.
