http://p4web.freebsd.org/@@210345?ac=10 Change 210345 by rwatson@rwatson_svr_ctsrd_mipsbuild on 2012/04/29 09:50:26 Remove exist stub MTL driver, which simply allowed memory mapping of the Terasic MTL's memory from userspace via a special device node, and replace with a larger driver suite, consisting of several sub-drivers capturing various aspects of MTL behaviour: - Simple memory-mapped driver for the MTL pixel frame buffer - Simple memory-mapped driver for the MTL control register set - Simple memory-mapped driver for the MTL text frame buffer - More complex syscons driver for the MTL text frame buffer In the future we will want to provide an ioctl-driver control path for the register set from both the driver-provided device nodes, and perhaps via syscons. Although in hardware there is significant overlap with the flash device on the DE4 due to sharing a physical bus, it is likely the DE4 flash driver for FreeBSD will be entirely independent in practice. This is just a code checkpoint, and will likely require significant refinement for the syscons aspects to work properly.
