Some machines use floppy controllers via the SysBus interface,
and don't need to pull in all the SysBus code.
Extract the SysBus specific code to a new unit: fdc-sysbus.c,
and add a new Kconfig symbol: "FDC_SYSBUS".

Some machines use floppy controllers via the SysBus interface,
and don't need to pull in all the ISA code.
Extract the ISA specific code to a new unit: fdc-isa.c, and
add a new Kconfig symbol: "FDC_ISA".
This allows us to remove the FIXME from commit dd0ff8191ab
("isa: express SuperIO dependencies with Kconfig").

With the introduction of the nvme-subsystem device we are really
cluttering up the hw/block directory.
As suggested by Philippe previously, move the nvme emulation to hw/nvme.

Add support for namespaces formatted with protection information. The
type of end-to-end data protection (i.e. Type 1, Type 2 or Type 3) is
selected with the `pi` nvme-ns device parameter. If the number of
metadata bytes is larger than 8, the `pil` nvme-ns device parameter may
be used to control the location of the 8-byte DIF tuple. The default
`pil` value of '0', causes the DIF tuple to be transferred as the last
8 bytes of the metadata. Set to 1 to store this in the first eight bytes
instead.

To support multi-path in QEMU NVMe device model, We need to have NVMe
subsystem hierarchy to map controllers and namespaces to a NVMe
subsystem.
This patch introduced a simple nvme-subsys device model. The subsystem
will be prepared with subsystem NQN with <subsys_id> provided in
nvme-subsys device:
ex) -device nvme-subsys,id=subsys0: nqn.2019-08.org.qemu:subsys0

Add more fine-grained selection by adding a CONFIG_TC58128
selector for the TC58128 eeprom.
As this device is only used by the Shix machine, add an entry
to the proper section in MAINTAINERS.

This adds support for multiple namespaces by introducing a new 'nvme-ns'
device model. The nvme device creates a bus named from the device name
('id'). The nvme-ns devices then connect to this and registers
themselves with the nvme device.
This changes how an nvme device is created. Example with two namespaces:
-drive file=nvme0n1.img,if=none,id=disk1
-drive file=nvme0n2.img,if=none,id=disk2
-device nvme,serial=deadbeef,id=nvme0
-device nvme-ns,drive=disk1,bus=nvme0,nsid=1
-device nvme-ns,drive=disk2,bus=nvme0,nsid=2
The drive property is kept on the nvme device to keep the change
backward compatible, but the property is now optional. Specifying a
drive for the nvme device will always create the namespace with nsid 1.
