Virgil Dupras f690cb2e5b recipes/rc2014/sdcard: use driver from blkfs
This completes the migration of all Collapse OS code into blkfs!

Virgil Dupras 7c692c1111 recipes/rc2014: include readln directly in stage 1
XPACK is more efficient than stripfc was, we can pack more stuff in 8K.
We now have enough space to fit readln.

Virgil Dupras a2f164ecc3 emul: bootstrap to stage2 from within Collapse OS!
Big bootstrapping change which greatly reduces the role of the modern
operating system in the bootstrapping process.

Virgil Dupras 389b23fe1a Change C<? mechanic
It's now a simple flag updated by the C< implementation. No more
routine pointer.

The goal is to avoid tons of "ok" during a LOAD operation.

Virgil Dupras 8d78ca9dac tests: add test_sdc
The SD card driver is a bit too slow to be bearable. I'll write
_crc16 in z80 and see how it goes.

Virgil Dupras b5c370a936 emul: embed blkfs in forth binary
This will allow us to read from blkfs in tests.

Virgil Dupras 1bd191e86a Move /emul/forth/* to /emul
Less noisy this way

Virgil Dupras 816563e2e3 Stop LOADing on ABORT
This is done by adding a "C<* override" layer that is reset to 0 on
ABORT.

The problem was that when ABORT happened during a LOAD, we had a
resetted RSP and started from a clean INTERPRET, but LOAD didn't
have the opportunity to restore C<*, which caused it to continue
interpreting from the faulty BLK.

With a C<* override, we don't need to *restore* C<*, we just need to
clear the override.

Virgil Dupras af39b37dd1 Replace the "> " prompt with the more traditional "ok" one
This is more than cosmetic, it's also highly usable. The presence
or absence of the "ok" message allows us to know whether the command
aborted. Previously, the "> " prompt appeared when the system expected
a prompt in the INTERPRET context, whether the previous command aborted
or not.

Also, this allows us to get rid of that ugly FLAGS global variable.

Virgil Dupras a19376df6c Copy ACIA driver to blkfs
We can get rid of acia.z80, but not of acia.fs yet, we still need it.

Virgil Dupras 7a0e63746f parse: don't validate 0x and 0b lengths
It doesn't serve much purpose and takes up many precious bytes. And,
after all, parsed didn't do it either...

Virgil Dupras d466c6d95d emul: make stage2 load z80a from blkfs
This allows us to remove forth/z80a.fs. Another big step towards
self-hosting!

Virgil Dupras 0892193cbe Copy z80a.fs to disk blocks
I don't remove z80a.fs yet because build process needs it, but that
will change shortly.

Virgil Dupras dfaa1dc101 link: add "offset" argument to RLDICT
As long as our target was the first word of the "user" dict, using
target's prev to compute offset was fine, but when the target is not
the first word, this system breaks down.

This is the case when, instead of including source code in our boot
binary, we paste it in Collapse OS' prompt.

Also, adjust RC2014 recipe to include stage 3 assembling instructions
with the "paste into prompt" method.

Virgil Dupras a2d89de557 drv/sdc: implement core words in z80
In addition to making the driver significantly faster, it allows us
to make SDC port configuration opaque to sdc.fs.
