* 'malta' of git://qemu.weilnetz.de/qemu:
malta: Fix display for LED array
malta: Use symbolic hardware addresses
malta: Always allocate flash memory
malta: Clean allocation of bios region alias
The 8-LED array was already implemented in the first commit to Malta,
but this implementation was incomplete.

The patch adds definitions of some hardware addresses and uses these
definitions.
It also replaces the type of all addresses from signed to unsigned values.
This is only a cosmetic change because addresses are unsigned values,
the functions called also expect unsigned values,
and we need no sign extension here.

There is no reason why there should not be a flash memory when the
Malta emulation is started with a Linux kernel. When flash memory
is always available, the code is simpler, and it can be better tested.

After commit 5312bd8b31 we got memory region relative offsets into our mmio
callbacks instead of page boundary based offsets.
This broke the OpenPIC emulation which expected offsets to be on page boundary
and substracted its region offset manually.
This patch gets rid of that manual substraction and lets the memory api do its
magic instead.

Currently, the function spapr_create_phb() uses its parameters to
initialize the correct memory windows for the new PCI Host Bridge
(PHB). This is not the way things are supposed to be done with qdevs,
and means you can't create extra PHBs easily using -device.
Since pSeries machines can and do have many PHBs with various
configurations, this is a real limitation, not just a theoretical.
This patch, therefore, alters the PHB initialization code to use qdev
properties to set these parameters of the new bridge, moving most of
the code from spapr_create_phb() to spapr_phb_init().
While we're at it, we change the naming of each PCI bus and its
associated memory regions to be less arbitrary and make it easier to
relate the guest and qemu views of memory to each other.

The pseries "xics" interrupt controller, like most interrupt
controllers can support both message (i.e. edge sensitive) interrupts
and level sensitive interrupts, but it needs to know which are which.
When I implemented the xics emulation for qemu, the only devices we
supported were the PAPR virtual IO devices. These devices only use
message interrupts, so they were the only ones I implemented in xics.
Since then, however, we have added support for PCI devices, which use
level sensitive interrupts. It turns out the message interrupt logic
still actually works most of the time for these, but there are
circumstances where we can lost interrupts due to the incorrect
interrupt logic.
This patch, therefore, implements the correct xics level-sensitive
interrupt logic. The type of the interrupt is set when a device
allocates a new xics interrupt.

The sPAPR PCI code defines a PCI device "spapr-pci-host-bridge-pci" which
is never used. This came over from the earlier bridge driver we used as
a template. Some other bridges appear on their own PCI bus as a device,
but that is not true of pSeries bridges, which are pure host to PCI with
no visible presence on the PCI side.

The kvmvapic code remaps a section of ROM as RAM to allow the guest to
maintain state there. It is careful to align the section size to a page
boundary, to avoid creating subpages, but neglects to do the same for
the start address. These leads to an assert later on when the memory
core tries to create a page which is half RAM and half ROM.
Fix by aligning the start address to a page boundary.
This can be triggered by running qemu-system-x86_64 -enable-kvm -vga none.

Currently, the "kvmclock" type is only registered when kvm_enabled().
This breaks when moving type registration to before command line
parsing (so that QOM types can be used for CPU and machine).
Since the QOM classes are lazy-initialized anyway and kvmclock_create()
has another kvm_enabled() check, simply drop the KVM check in
kvmclock_register_types().
kvm-i8259, kvm-apic and kvm-ioapic do not suffer from such a check.

This patch fixes two bugs in the OHCI device where the device writes
back data to system memory that should be exclusively under the
control of the guest side driver.
In OHCI specification Section 5.2.7, it mentioned "In all cases, Host
Controller Driver is responsible for the insertion and removal of all
Endpoint Descriptors in the various Host Controller Endpoint
Descriptor lists". In the ohci_frame_boundary(), ohci_put_hcca()
writes the entire hcca back including the interrupt ED lists which
should be under driver control. This violates the specification and
can race with a host driver updating that list at the same time.
In the OHCI Spec Section 4.6, Transfer Descriptor Queue Processing, it
mentioned "Since the TD pointed to by TailP is not accessed by the HC,
the Host Controller Driver can initialize that TD and link at least
one other to it without creating a coherency or synchronization
problem". While the function ohci_put_ed() writes the entire endpoint
descriptor back including the TailP which should under driver
control. This violate the specification and can race with a host
driver updating the TD list at the same time.
In each case the solution is to make sure we don't write data which is
under driver control.
