Subject: [PATCH 0/3] hw/arm: Pack the QEMU generated device tree
Date: Mon, 15 Jan 2024 12:34:27 +0800 [thread overview]
Message-ID: <20240115043431.3900922-1-bin.meng@windriver.com> (raw)
By default, QEMU generates a 1 MiB sized device tree. This appears
to be unnecessary, as the actual size is much smaller than what the
DTB header claims. Let's pack it to save some room.
