-The following points clarify the QEMU license:
+The QEMU distribution includes both the QEMU emulator and
+various firmware files. These are separate programs that are
+distributed together for our users' convenience, and they have
+separate licenses.
-1) QEMU as a whole is released under the GNU General Public License,
-version 2.
+The following points clarify the license of the QEMU emulator:
-2) Parts of QEMU have specific licenses which are compatible with the
-GNU General Public License, version 2. Hence each source file contains
-its own licensing information. Source files with no licensing information
-are released under the GNU General Public License, version 2 or (at your
-option) any later version.

+- OpenSBI (https://github.com/riscv/opensbi) aims to provide an open-source
+ reference implementation of the RISC-V Supervisor Binary Interface (SBI)
+ specifications for platform-specific firmwares executing in M-mode. For all
+ supported platforms, OpenSBI provides several runtime firmware examples.
+ These example firmwares can be used to replace the legacy riscv-pk bootloader
+ and enable the use of well-known bootloaders such as U-Boot.
