      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   sigsetjmp/siglongjmp missing....
     11 
     12     o   Add more videomodes to pccons driver. 50kHz and 64kHz monitors?
     13 	This seems to be hard. Need more info on the chip.
     14 
     15     o   Find out why bitmap load to S3-928 flashes screen.
     16 	Know why (enable linear mode). Need S3 info.
     17 
     18     o   Can we have 32 double registers?
     19 
     20     o	64bit kernel/userland
     21 
     22     o	source code structure is quite obsolete,
     23 	general clean up is needed as nisimura-san suggested.
     24 	especially:
     25 
     26  	-   introduce struct platform and remove ugly ``switch (cputype)''
     27 	    in many places.
     28 
     29 	-   implement and use bus_dma
     30 
     31 	-   clean up bus_space implementation, remove inb/outb
     32 
     33 	-   eliminate OpenBSD compat #define symbols
     34 
     35     o	fix kernel start address
     36 
     37     o	merge new wscons
     38 
     39     o	parse ARC BIOS configuration information and use it
     40 
     41     o	fix implementation of DELAY(), clean up clock implementation
     42 
     43     o	if_sn.c ether address handling clean up
     44 
     45     o	use MI driver
     46 
     47 	-   use MI ncr53c9x driver instead of home grown asc
     48 
     49 	-   use MI bha driver instead of home grown btl
     50 
     51 	-   make sonic driver MI, and share it with mac68k, newsmips/apbus
     52 
     53 	-   make fd driver MI, and share it with i386
     54 	    (contact christos about MI fd driver)
     55 
     56 	-   make pccons MI, and share it with i386,
     57 	    or simply eliminate pccons
     58 
     59 Lots of other things.....
