 * write some procedures for dumping registers and other stuff (for use in debugging); maybe print registers' contents on data/prefetch abort?
 
+* Memory regions can be configured as one of several types, which affects how memory reads/writes are performed by the processor. Dig into that and use the best appropriate settings in paging.c (i.e. normal memory instead of strongly-ordered memory for RAM).

 * partially DONE - one can always add more, but we have the most important stuff * Implement some basic utilities for us to use (memcpy, printf, etc...)
 
 * partailly DONE - svc works; once we implement processes we could also kill them on aborts * develop userspace process supervision (handling of interrupt caused by svc instruction, proper handling of other data abort, undefined instruction, etc.)
