The defs.h header will take care of including the various config.h
headers. For now, it's just config.h, but we'll add more when we
integrate gnulib in.
This header should be used instead of config.h, and should be the
first include in every .c file. We won't rely on the old behavior
where we expected files to include the port's sim-main.h which then
includes the common sim-basics.h which then includes config.h. We
have a ton of code that includes things before sim-main.h, and it
sometimes needs to be that way. Creating a dedicated header avoids
the ordering mess and implicit inclusion that shows up otherwise.

This commits the result of running gdb/copyright.py as per our Start
of New Year procedure...
gdb/ChangeLog
Update copyright year range in copyright header of all GDB files.

gdb/ChangeLog:
Update copyright year range in all GDB files.
|
|
This commit applies all changes made after running the gdb/copyright.py
script.
Note that one file was flagged by the script, due to an invalid
copyright header
(gdb/unittests/basic_string_view/element_access/char/empty.cc).
As the file was copied from GCC's libstdc++-v3 testsuite, this commit
leaves this file untouched for the time being; a patch to fix the header
was sent to gcc-patches first.

This applies the second part of GDB's End of Year Procedure, which
updates the copyright year range in all of GDB's files.

The bfin port is using the WITH_DEVICES framework for two reasons:
- get access to the cpu making the request (if available)
- check the alignment & size for core & system MMRs
We addressed the first part with commit dea10706e9159ba6e94eab4c25010f3,
and we handle the second part with this commit. Arguably this is more
correct too because trying to do bad reads/writes directly (when devices
support is disabled) often results in bad memory accesses.
As part of this clean up, we also adjust all of the existing logic that
would reject invalid accesses: the code was relying on the checks never
returning, but that's not the case when things like gdb (via the user's
commands) are making the requests. Thus we'd still end up with bad mem
accesses, or sometimes gdb being hung due to while(1) loops.
Now we can connect (most of) these models into any address and have them
work correctly.

Two modifications:
1. The addition of 2013 to the copyright year range for every file;
2. The use of a single year range, instead of potentially multiple
year ranges, as approved by the FSF.

Make all of the pins bidirectional, and support sending signals when
software drives the pins as outputs.

When the mask a/b MMRs are written, the output signal might change levels
(as pins are [un]masked), so make sure we update the output level.
Further, make sure we handle edge ints correctly by first sending a high
signal followed by a low signal.

Each GPIO block has 16 pins, and I only added 15 in the original
port list. So add the missing 16th.

Makes it a lot easier to find out what's going on with interrupt lines
if the ports have tracing output.

We need the DIR bit cleared, not set, in order for the pin to be treated
as an input.
When looking up the data value, we need to shift the "level" value over by
"my_port" rather than "bit" as the latter has already been shifted over.
We also should normalize the "level" coming in from the outside worlds to
the set of {0,1} since those are the only values that matter to GPIOs.
We need the BOTH bit set, not cleared, in order for the pin to trigger
on both edges.

The clear/set/toggle MMRs aren't backed by "real" data; they implicitly
perform bit operations on the associated data register. So when we go
to process writes to them, we need to adjust the pointer accordingly so
that the actual backing data is modified.

When I originally wrote the w1c helper funcs, I used it in a few places.
Then I forgot how it worked and when I later documented it, I described
the 3rd arg in the exact opposite way it is actually used. This error
propagated to a bunch of devices registers that were not explicitly
tested (a bunch of the devices are stubs which merely exist to say "no
device is connected" to make device drivers happy).
So once the documentation is unscrewed, fix all of the broken call sites.

This takes care of the MMR interface and pushing up interrupts.
