Whilst trying to improve QEMU's ESP SCSI implementation with regard to the NCR datasheet, I noticed that SeaBIOS would fail to boot one of my Debian test images with my patches applied.Further investigation revealed that the SeaBIOS esp-scsi driver inadvertently relies on existing bugs in QEMU's ESP SCSI emulation to work correctly, so this series changes the driver to work as described in the NCR datasheet. With this series applied it is possible for the updated SeaBIOS to boot both QEMU current git HEAD as well as my local WIP branch containing various fixes and improvements to QEMU's ESP SCSI emulation.
