NetBSD/sys/arch/arm32/doc/TODO

Ok this is the current todo list.

There are a number of things that need to be done that I do not
have time to do and am unlikely to have time to do them in the near
future. These are currently being left in the hope that users will do them
instead and are marked with *.

1.  replace netinet/in_cksum.c with an assembly version (*)
2.  replace netns/ns_chsum.c with an assembly version (*)
3.  drivers for currently unsupported podules (*)
4.  replacing the C string functions in libc with assembly ones (work
    started but not finished) (*)
5.  porting libpthread to arm32 architecture (*)
6.  the ARM FPE postproc handler should check need_resched and CURSIG()
    in the assembly glue and only switch to SVC and do a userret() if
    required. UNDER DEVELOPMENT
7.  L1 page tables should be freed when a process is swapped out and
    reallocated when the process is swapped in.
8.  bcopy() needs optimising. (*)
9.  cleanup video DRAM support on machine with VRAM
10. clean up prototype declarations
11. support reading and writing the rtc device UNDER DEVELOPMENT
