Subject: [PATCH] hw: Use QEMU_IS_ALIGNED() on parallel flash block size
Date: Mon, 11 May 2020 22:52:46 +0200 [thread overview]
Message-ID: <20200511205246.24621-1-philmd@redhat.com> (raw)
Use the QEMU_IS_ALIGNED() macro to verify the flash block size
is properly aligned. It is quicker to process when reviewing.
