Personally I find KDL hangman the biggest blocker, but oh well...

* Figure out how to get page flags (modified/accessed) and implement it ;)
* Fix serial port mapping. Currently kernel uses the haiku_loader identity
mapping for it, but this lives in user virtual address space...
(Need to not use identity mapping in haiku_loader but just
map_physical_memory() there too so it can be handed over without issues).
* Seperate ARM architecture/System-On-Chip IP code. Needed very early on
(Interrupt Controller, Timer IP block). Should use FDT for this too.
* Use FDT to remove all the seperate board definitions in the build. Use a
"minimal ARM architecture version" as the compile flag for ARM support.
This to be able to optimize a kernel build for a specific SoC (or family).
* Research stack unwinding to implement backtrace support for KDL & friends.
* Add KDL hangman to the boot floppy image for more enjoyment during porting....
* Userland...........
