6dd9d349fc pci: support shared irqs (x86)
Step to move shared irq handling out of core in the long run. So, use
irq_proxy implementation from base in os and implement shared irq handling
in platform driver of x86 (pci_drv).

85599c072f os: use async IRQ and server lib in drivers
Use the new asynchronous IRQ interface in the mostly used drivers, e.g.:

* ahci_drv: x86/exynos5
* gpio_drv: imx53/omap4
* input_drv: imx53/dummy
* ps2_drv: x86/pl050
* timer_drv

Now, the Irq_session is requested from Gpio::Session:

From now on we use an asynchronous IRQ interface. To prevent triggering
another GPIO IRQ while currently handling the former one, IRQs must
now by acknowledged explicitly. While here, we also changed the GPIO
session interface regarding IRQ management. The generic GPIO component
now wraps the Irq_session managed by the backend instead of using the
GPIO backend methods directly. A client using the GPIO session may
request the Irq_session_capability by calling
'Gpio::Session::irq_session()' and can use this capability when using
a local Irq_session_client.

91e0a5d5dd SD-card driver for the Raspberry Pi
The driver operates in PIO mode only. Depending on the block size (512
bytes versus 128 KiB), it has a troughput of 2 MiB/sec - 10 MiB/sec for
reading and 173 KiB/sec - 8 MiB/sec for writing.

77cba65b7a os: detection of standard-capacity SD cards
This patch enhances the generic SD-card protocol implementation in
sd-card.h with the ability to handle the version 1.0 of the CSD register
(containing the capacity information of older SD cards).

dd47129bef nic session: link-state change handling
A Nic::Session client can install a signal handler that is used to
propagate changes of the link-state by calling 'link_state_sigh()'.
The actual link state is queried via 'link_state()'.

The nic-driver interface now provides a Driver_notification callback,
which is used to forward link-state changes from the driver to the
Nic::Session_component.

The following drivers now provide real link state: dde_ipxe, nic_bridge,
and usb_drv. Currently, OpenVPN, Linux nic_drv, and lan9118 do not
support link state and always report link up.

98616a1812 i.MX53: SD-card driver and bench
The driver for the Freescale eSDHCv2 doesn't support the highest
available bus frequency by now and also the bus width may be set to a
higher value but that needs further checks on the capabilities of the
inserted card.

The commits provide a benchmark as it exists for the OMAP4 SDHC driver.

2380fc442f ahci: avoid to reinstantiate backend driver
Instead of fixing the missing dynamic facilities of the AHCI driver
backends for x86 and Exynos5, just avoid to create/destroy the backend
for every new connection, but always use one and the same object.
The AHCI drivers need to be re-written anyway, see issue #1352 for instance,
we can make it more robust for the dynamic case then.

786fe805da base: introduce caching attributes (fix #1184)
On ARM it's relevant to not only distinguish between ordinary cached memory
and write-combined one, but also having non-cached memory too. To insert the
appropriated page table entries e.g.: in the base-hw kernel, we need to preserve
the information about the kind of memory from allocation until the pager
resolves a page fault. Therefore, this commit introduces a new Cache_attribute
type, and replaces the write_combined boolean with the new type where necessary.

0ed68a56b7 Use signals for delivering input events
This patch changes both the Input::Session interface and the skeleton
for the server-side implementation of this interface
('input/component.h').

The Input::Session interface offers a new 'sigh' function, which can be
called be the client to register a signal handler. The signal handler
gets notified on the arrival of new input. This alleviates the need to
poll for input events at the client side.

The server-side skeleton for implementing input services underwent a
redesign to make it more modular and robust. I.e., there are no
global functions needed at the server side and the event-queue
enable/disable mechanism is implemented at a central place (in the root
component) rather than inside each driver.
