1) Add the NVRAM device. This device allows us to speak with the nvram on prep-based machines and read/write to it. Also add a simple IOCTL interface for speaking with the nvram from userland. This hasn't been tested yet, but eventually I plan to support it with the sparc eeprom command. 2) Change the root device detection to use the nvram device to attempt to guess the boot device. Most machines should now correctly guess thier boot device, though I expect a few devices to still not work quite right yet. 3) change the default IRQ to level rather than edge in the pnpbus if the flags are invalid or empty. (based on output from a PowerStack E1) 4) correctly handle older machines in pnpbus that have FixedIOPorts rather than variable ones. Still have much to do. |
