target-ppc: Add versions to server CPU descriptions

QEMU is running on. For example, this allowed specifying "-cpu POWER7"

pseries: Move rtc_offset into RTC device's state structure
The initial creation of the PAPR RTC qdev class left a wart - the rtc's
offset was left in the sPAPREnvironment structure, accessed via a global.
This patch moves it into the RTC device's own state structure, were it
belongs. This requires a small change to the migration stream format. In
order to handle incoming streams from older versions, we also need to
retain the rtc_offset field in the sPAPREnvironment structure, so that it
can be loaded into via the vmsd, then pushed into the RTC device.
Since we're changing the migration format, this also takes the opportunity
to:
* Change the rtc offset from a value in seconds to a value in
nanoseconds, allowing nanosecond offsets between host and guest
rtc time, if desired.
* Remove both the already unused "next_irq" field and now unused
"rtc_offset" field from the new version of the spapr migration
stream

This patch makes the PAPR RTC a separate device in the qemu device model.
For now, the only piece of device state - the rtc_offset - is still kept in
the global sPAPREnvironment structure. That's clearly wrong, but leaving
it to be fixed in a following patch makes for a clearer separation between

Out current implementations of those work directly off host time (with

This patch reworks the RTAS RTC code to respect those options, primarily
by basing them on the qemu_clock_get_ns(rtc_clock) function instead of

event messages from the hypervisor to the guest.
Currently both call qemu_get_timedate() directly, but we want to change
that so we can properly handle the various -rtc options. In preparation,
create a helper function to return the virtual RTC time.

pseries: Add more parameter validation in RTAS time of day functions
Currently, the RTAS time of day functions only partially validate the
number of parameters they receive and return. Because of how the
parameters are used, this is unlikely to lead to a crash, but it's messy.
This patch adds the missing checks.

Generalize QOM publishing of date and time from mc146818rtc.c
The mc146818rtc driver exposes the current RTC date and time via the "date"
property in QOM (which is also aliased to the machine's "rtc-time"
property). Currently it uses a custom visitor function rtc_get_date to
do this.
This patch introduces new helpers to the QOM core to expose struct tm
valued properties via a getter function, so that this functionality can be
more easily duplicated in other RTC implementations.

spapr-pci: Enable huge BARs
At the moment sPAPR only supports 512MB window for MMIO BARs. However
modern devices might want bigger 64bit BARs.
This extends MMIO window from 512MB to 62GB (aligned to
SPAPR_PCI_WINDOW_SPACING) and advertises it in 2 records in
the PHB "ranges" property. 32bit gets the space from
SPAPR_PCI_MEM_WIN_BUS_OFFSET till the end of 4GB, 64bit gets the rest
of the space. If no space is left, 64bit range is not advertised.
The MMIO space size is set to old value of 0x20000000 by default
for pseries machines older than 2.3.
The approach changes the device tree which is a guest visible change, however
it won't break migration as:
1. we do not support migration to older QEMU versions
2. migration to newer QEMU will migrate the device tree as well and since
the new layout only extends the old one and does not change address mappigns,
no breakage is expected here too.
SLOF change is required to utilize this extension.

pseries: Limit PCI host bridge "index" value
pseries guests can have large numbers of PCI host bridges. To avoid the
user having to specify a number of different configuration values for every
one, the device supports an "index" property which is a shorthand setting
the various window and configuration addresses from a predefined sensible
set.
There are some problems with the details at present:
* The "index" propery is signed, but negative values will create PCI
windows below where we expect, potentially colliding with other devices
* No limit is imposed on the "index" property and large values can
translate to extremely large window addresses. With PCI passthrough in
particular this can mean we exceed various mapping and physical address
limits causing the guest host bridge to not work in strange ways.
This patch addresses this, by making "index" unsigned, and imposing a
limit. Currently the limit allows indices from 0..255 which is probably
enough host bridges for the time being. It's fairly easy to extend if
we discover we need more.

spapr_vio/spapr_iommu: Move VIO bypass where it belongs
Instead of tweaking a TCE table device by adding there a bypass flag,
let's add an alias to RAM and IOMMU memory region, and enable/disable
those according to the selected bypass mode.
This way IOMMU memory region can have size of the actual window rather
than ram_size which is essential for upcoming DDW support.
This moves bypass logic to VIO layer and keeps @bypass flag in TCE table
for migration compatibility only. This replaces spapr_tce_set_bypass()
calls with explicit assignment to avoid confusion as the function could
do something more that just syncing the @bypass flag.
This adds a pointer to VIO device into the sPAPRTCETable struct to provide
the sPAPRTCETable device a way to update bypass mode for the VIO device.
