Mostly determined from reverse engineering and poking around.
Includes first "experiments" program with random bits and pieces for
poking at registers, may be useful to keep in source control but not
useful for writing actual programs.
- Fix dir-locals so emacs won't inject occasional tabs to case statements.
- Fix stray tab indentation in example programs. (Thx @pfalcon for pointing this out)
Closes#7.
It'd be nice to change the linker script so .text is always linked to
IROM instead of needing to objcopy each compiled file. The sticking
point for this is libgcc & libhal, which have symbols in .text that need
to be loaded to IRAM.
