The idea is to consider assemblers as "runtime" apps instead of
placing them in the "bootstrap" section of the blocks. These apps
will be used for much more than bootstrapping.
Moved its documentation to doc/asm.txt and made its code blocks
more compact.
The few extra bytes they save in the core aren't worth the extra
complexity. This was initially done in a context where I had
troubles keeping the RC2014 binary with SDC inside the 8K limit.
At this point, even with the few extra bytes we add here, we're at
7200 bytes, so I'd say we're fine.
After having done my initial handshaking, I thought the rest of the
job was only a matter of implementing the protocol, but I was wrong.
There were many issues to fix before I could reliably communicate
with my 328P, mostly timing.
Now, I seem to be able to reliably extract fuse information, but
only in batch mode (that is, run "asp$ aspfl@" directly, then
running "(spid)" before running the next command). If I try to
interact with the chip in a single asp$ session, I sometimes get
wrong values (but no sync error! that's worrying...).
Although the SPI Relay driver is RC2014-specific, the SD Card driver
is generic enough to be a subsystem. That's the second subsystem we
add and this warrants, I think, the formalization of a new concept:
protocols.
Now that the boot binary is fully cross-compiled, there's no use for
the linker anymore. Theoretically, it could still be useful, but I
can't think of a real use case.
Let's take it out of the picture. If it's ever needed again, I'll
know where to find it.
Now that this section is so small, I think I can see a possibility
for cross-compiling Collapse OS entirely, which would be great
because we could get rid of the relinker.
