Virgil Dupras b536d3bfd6 rc2014: complete the EEPROM recipe 2020-04-13 14:41:02 -04:00
Virgil Dupras d0545d555f upload: use A! instead of C! 
It makes the tool much more versatile. I'll have adev being included
in all recipes, so it can be assumed.

Virgil Dupras d08a9711c5 boot: make HERE point to RAMEND instead of CURRENT 
The former was only used in the peculiar context of "/emul". The
regular case is actually HERE pointing to RAMEND on boot.

Virgil Dupras c515720e23 Revert "Remove link.fs" 
Let's revisit the relinking approach, with LITA this time.
This reverts commit 6652125d47.

Virgil Dupras 6368cc3bac Remove (sysv) 
Replace its usages with direct RAM+ offsets. The (sysv) mechanism was
incompatible with cross-compilation of a full interpreter.

Virgil Dupras 019d05f64c Make the shell a userspace app 
That's my mega-commit you've all been waiting for.

The code for the shell share more routines with userspace apps than with kernel
units, because, well, its behavior is that of a userspace app, not a device
driver.

This created a weird situation with libraries and jump tables. Some routine
belonging to the `kernel/` directory felt weird there.

And then comes `apps/basic`, which will likely share even more code with the
shell. I was seeing myself creating huge jump tables to reuse code from the
shell. It didn't feel right.

Moreover, we'll probably want basic-like apps to optionnally replace the shell.

So here I am with this huge change in the project structure. I didn't test all
recipes on hardware yet, I will do later. I might have broken some...

But now, the structure feels better and the line between what belongs to
`kernel` and what belongs to `apps` feels clearer.

Virgil Dupras cdd0b64570 Modify userspace .org and RAMSTART expectations 
Instead of expecting a `USER_CODE` symbol to be set, we expect `.org` to be
set in all userspace glue code. This gives us more flexibility with regards to
how we manage that.

Moreover, instead of making `USER_RAMSTART` mandatory, we make it default to
the end of the binary, which is adequate in a majority of cases.

Will be useful for my upcoming mega-commit... :)

Virgil Dupras 7cf3ed38da Extract str.asm from core.asm and make core included by userspace 
Most of register fiddling routines (which is now the only thing contained
in care.asm) are used by almost all userspace apps, often in inner loops.

That makes the penalty of using jump tables for those a bit too high.
Moreover, it burdens jump tables needlessly.

Because this unit is very small (now that string routines are out), it makes
sense to always include it in binaries.

Virgil Dupras 7274dccbe7 Move ASCII consts to ascii.h 
And made them shorter in name. The new ascii.h file allow reuse in userspace
code.

Virgil Dupras 2a55bfd375 stdio: remove a layer of indirection in GetC/PutC 
We use zasm's ability to use labels in .equ directive.

We didn't do it before because for a while, we were in between scas
and zasm (scas was used in automated tests) so we needed to use the
lowest common denominator: zasm doesn't have macros and scas can't
use labels in .equ directives.

This forced us to add this layer of indirection. But now that we are
completely cut from scas' dependency, we can use this nice zasm's
ability.

are canonical.

Virgil Dupras b745f49186 Rename blockdev's API routines to GetB/PutB 
The goal is to avoid mixing those routines with "character devices"
(acia, vpd, kbd) which aren't block devices and have routines that
have different expectations.

This is a first step to fixing #64.
