isa_fdc_get_drive_type() is needed by pc machine types
when setting up the cmos.
Move to separate source file so we can keep it in core qemu
when building floppy as module.

isa_fdc_init_drives() is called by pc machine setup,
and it depends on fdctrl_init_drives().
Move both functions to separate source file so we can
keep them in core qemu when building floppy as module.

Allows to enable/disable the floppy controller. Default depends on
MachineClass->no_floppy. It's ON for now, but we can flip the default
for 6.2+ machine types.
NOTE: This requires -nodefaults or no_floppy=1 to actually have an
effect. Otherwise the default floppy drive created by qemu will
auto-enable the floppy controller. Not sure how to deal with that best.
IMHO we should simply stop creating a default floppy, unfortunaly
that will break live migration.

Mark suggested:
You may be able to simplify this further by removing the
global legacy init functions fdctrl_init_sysbus() and
sun4m_fdctrl_init(): from what I can see fdctrl_init_sysbus()
is only used in hw/mips/jazz.c and sun4m_fdctrl_init() is only
used in hw/sparc/sun4m.c so you might as well inline them or
move the functions to the relevant files.
I did it and plan to send during 6.2. Sounds simpler than module.
You could easily rebase your series on top (or I can include your
patches while sending).

Feel free to include them. But I can also rebase when your patches
landed upstream. Your choice ;)

What's the plan here, what are we trying to solve with this series
*exactly*?
If Phil sends his cleanups, do we still want/need the modularization here?
For now I'm gonna shuffle these off of my review queue and I assume I'll
see a respin/rebase from either you or phil during the 6.2 window, let me
know if this is wrong.
Thanks,

Both series are orthogonal, but if my cleanups get merged first, there
is less floppy code to modularize.

This is OK. Probably easier for everybody if I can rebase/include Gerd's
patches along. I'm still not convinced FDC modularization is the right
way to go; but the PC machine is one of machines I know the less, and
has inherited a lot of odd things, so I need to carefully audit few more
things.
I'd rather have faithful chipsets modelled. Long term I don't think
FDC are going away from QEMU, as they are used by happy hobbyist running
old DOS programs from the 80's. But being able to build QEMU without
FDC would be nice indeed.

OK, Understood -- And you're right, upstream the FDC needs a bit of work
and love, because they are used and important. I just ... as you can tell,
don't have much time to give them that love myself.
*cough* *cough* *nudge* *wink*
I'll be sending a patch when 6.2 opens indicating my desire to step down
from the device.
