      2 
      3 To do list (not in any particular order).
      4 
      5     o	Move the RO and WIRED attribute from the pte to the pv table.
      6 	This saves four instructions in the tlb miss handler.
      7 
      8     o   Boot. Standalone boot program instead of booting the kernel directly?
      9 
     10     o   Find out why bitmap load to S3-928 flashes screen. (X server)
     11 	Know why (enable linear mode). Need S3 info.
     12 
     13     o   Can we have 32 double registers?
     14 
     15     o	64bit kernel/userland
     16 
     17     o	repair DeskStation and Algor support
     18 
     19 	-   64bit device physical address space for Tyne (see OpenBSD pmap.c)
     20 
     21 	-   requires bus_dma
     22 
     23     o	source code structure is quite obsolete,
     24 	general clean up is needed as nisimura-san suggested.
     25 	especially:
     26 
     27  	-   introduce struct platform and remove ugly ``switch (cputype)''
     28 	    in many places.
     29 
     30 	-   implement and use bus_dma
     31 
     32 	-   clean up bus_space implementation, remove inb/outb
     33 
     34     o	fix kernel start address
     35 
     36     o	merge new wscons
     37 
     38     o	parse ARC BIOS configuration information and use it
     39 
     40     o	omit __BROKEN_CONFIG_UNIT_USAGE
     41 
     42     o	omit __SWAP_BROKEN in <mips/types.h>
     43 
     44     o	fix implementation of DELAY(), clean up clock implementation
     45 
     46     o	asc.c scsi clock/NCR53CF94 handling clean up
     47 
     48     o	if_sn.c ether address handling clean up
     49 
     50     o	com_lbus.c clock handling clean up
     51 
     52     o	implement NCR 53c700(?) driver for NEC RISCserver 2200
     53 	based on amiga siop driver?
     54 
     55     o	use MI driver
     56 
     57 	-   use MI ncr53c9x driver instead of home grown asc
     58 
     59 	-   use MI bha driver instead of home grown btl
     60 
     61 	-   make sonic driver MI, and share it with mac68k, newsmips/apbus
     62 
     63 	-   make fd driver MI, and share it with i386
     64 	    (contact christos about MI fd driver)
     65 
     66 	-   make pccons MI, and share it with i386,
     67 	    or simply eliminate pccons
     68 
     69     o easy part
     70 
     71 	- ARC boot device name -> NetBSD root device conversion
     72 
     73 	- and missing MI devices
     74 		lkm, tun, vcoda, raidframe, ...
     75 
     76 	- way to specify serial console
     77 
     78     o resolve "XXX"
     79 
     80 Lots of other things.....
