Add has_mem64 for struct host_bridge, on root bus that does not support
mmio64 above 4g, will not set that.
We will use that info next two following patches:
1. Don't treat non-pref mmio64 as pref mmio, so will not put
it under bridge's pref range when rescan the devices
2. will keep pref mmio6
For device resource PREF bit setting under bridge 64-bit pref resource,
we need to make sure only set PREF for 64bit resource, so set
IORESOUCE_MEM_64 for 64bit resource during OF device resource flags
parsing.

During sorting before assign, we only put resource with non-zero align
in the sorted list, so for optional resources that required size is 0 and
only have optional parts, we need to have correct align.
While treating SRIOV as optional resources, we always read alignment for
SRIOV bars every time,
There are several calling to window_alignment(), and we will have more
for alt_size support, cache the value instead of keeping on getting it.

We try to assign required+optional at first, and we only accept the result

This patch adds the new passive governor for DEVFREQ framework. The following
governors are already present and used for DVFS (Dynamic Voltage and Frequency
Scaling) drivers. The following governors are independently used for one device
driver which don't give the influence to other device drviers

This patch modifies the following sysfs entry of DEVFREQ framework
because the devfreq device using passive governor don't need the same
information of the devfreq device using rest governor.
- polling_interval: passive gov don't use the sampling rate.
- available_governors : passive gov don't

On hotplug path, we can not touch sibling bridges that is outside
of the slot.
That could happen when BIOS does not assign some bridge BARs and
later kernel can not assign resource to them in first try.
Check if fail dev is the parent bridge, then just use subordinate
bus instead use parent bus.
Current realloc path would not shrink bridge resource through
pbus_size_mem() checking with the old size.
That cause problem: when "required+optional" resource allocation fails,
the cached bridge resource size will prevent "required" resource to get
allocated smaller resource.
Clear the old resou
For device resource PREF bit setting under bridge 64-bit pref resource,
we need to make sure only set PREF for 64bit resource, so set
IORESOUCE_MEM_64 for 64bit resource during of device resource flags

This patch adds the bus nodes using VDD_INT for Exynos3250 SoC.
Exynos3250 has following AXI buses to translate data between
DRAM and sub-blocks.
Following list specifies the detailed relation between DRAM and sub-blocks:
- ACLK400 clock for MCUISP
- ACLK266 clock for ISP
- ACLK200 clock for FSYS

Exynos4x12 has the following AXI buses to translate data between

Hi,
After 5b28541552ef (PCI: Restrict 64-bit prefetchable bridge windows
to 64-bit resources), we have several reports on resource allocation
failure, and we try to fix the problem with resource clip, and find
more problems.
One is realloc fail with two graphics cards above 4G.
One is from sparc
Same as sparc version.
Make resource with consistent sequence
like other arch or directly from pci_read_bridge_bases(),
even non-pref mmio is missing, or out of ordering in firmware reporting.
So hold i = 1 for non pref mmio, and i = 2 for pref mmio.
