This series includes the OpenSBI firmware for QEMU RISC-V users. To avoid breakages we have not changed the default behaviour of QEMU. The plan is to change the default though, which is why an entry to the qemu-deprecated.texi file has been added as well as a new warning.
After this series QEMU 4.1 has three options: 1. ``-bios none`` - This is the current default behavior if no -bios option is included. QEMU will not automatically load any firmware. It is up to the user to load all the images they need. 2. ``-bios default`` - In a future QEMU release this will become the default behaviour if no -bios option is specified. This option will load the default OpenSBI firmware automatically. The firmware is included with the QEMU release and no user interaction is required. All a user needs to do is specify the kernel they want to boot with the -kernel option 3. ``-bios <file>`` - Tells QEMU to load the specified file as the firmwrae. All users should transition to using a -bios option. We can start updating all documentation after the release of 4.1. At the end of this series and the transition period we are in the good place of no longer requiring users to build firmware to boot a kernel. Instead users can just run QEMU with the -kernel option and everything will work. They can also override the firmware with their own using the -bios option. Using "-bios none" will result in no firmware being loaded (as it is today). This is based on my original series adding OpenSBI support but now has improved documentation changes around the license.
