ff788b7022 hw/adc: Remove MAX111X device
The MAX111X ADC device was used only by the XScale-based
Zaurus machine types. Now they have all been removed, we can
drop this device model too.

Because this device is an SSI device, in theory it could be created
by users on the command line for boards with a different SSI
controller, but we don't believe users are doing this -- it would be
impossible on the command line to connect up the GPIO inputs which
correspond to ADC inputs, or the GPIO output which is an interrupt
line.  The only example a web search produces for "device max1111" or
"device max1110" is our own bug report
  https://gitlab.com/qemu-project/qemu/-/issues/2228
where it's used as an example of a bogus command that causes an
assertion in an aspeed machine type that wasn't expecting anything
other than flash devices on its SMC bus.

ad80e36744 hw, target: Add ResetType argument to hold and exit phase methods
We pass a ResetType argument to the Resettable class enter
phase method, but we don't pass it to hold and exit, even though
the callsites have it readily available. This means that if
a device cared about the ResetType it would need to record it
in the enter phase method to use later on. Pass the type to
all three of the phase methods to avoid having to do that.

5ee0abed51 clock: Add ClockEvent parameter to callbacks
The Clock framework allows users to specify a callback which is
called after the clock's period has been updated.  Some users need to
also have a callback which is called before the clock period is
updated.

As the first step in adding support for notifying Clock users on
pre-update events, add an argument to the ClockCallback to specify
what event is being notified, and add an argument to the various
functions for registering a callback to specify which events are
of interest to that callback.

Note that the documentation update renders correct the previously
incorrect claim in 'Adding a new clock' that callbacks "will be
explained in a following section".

 - [0x50 - 0xff] reserved

All registers are 32-bit (thus when the datasheet mentions the
last defined register is 0x4c, it means its address range is
0x4c .. 0x4f.

This model implementation is also 32-bit. Set MemoryRegionOps

little endian variants like qemu-system-sh4 and qemu-system-sh4eb,
so that we do not have to compile the code multiple times anymore.

Whenever a symbol is referenced from multiple subdirectories, the

These symbols have to be added manually to the Kconfig files.

2562755ee7 maint: Fix macros with broken 'do/while(0); ' usage
The point of writing a macro embedded in a 'do { ... } while (0)'
loop (particularly if the macro has multiple statements or would
otherwise end with an 'if' statement) is so that the macro can be
used as a drop-in statement with the caller supplying the
trailing ';'.  Although our coding style frowns on brace-less 'if':
  if (cond)
    statement;
  else
    something else;
that is the classic case where failure to use do/while(0) wrapping
would cause the 'else' to pair with any embedded 'if' in the macro
rather than the intended outer 'if'.  But conversely, if the macro
includes an embedded ';', then the same brace-less coding style
would now have two statements, making the 'else' a syntax error
rather than pairing with the outer 'if'.  Thus, even though our
coding style with required braces is not impacted, ending a macro
with ';' makes our code harder to port to projects that use
brace-less styles.

The change should have no semantic impact.  I was not able to
fully compile-test all of the changes (as some of them are
examples of the ugly bit-rotting debug print statements that are
completely elided by default, and I didn't want to recompile
with the necessary -D witnesses - cleaning those up is left as a
bite-sized task for another day); I did, however, audit that for
all files touched, all callers of the changed macros DID supply
a trailing ';' at the callsite, and did not appear to be used
as part of a brace-less conditional.

Found mechanically via: $ git grep -B1 'while (0);' | grep -A1 \\\\
