8e9e866161 Unify framebuffer driver binary names (fix #720)
Introduce 'framebuffer' SPEC variable to distinguish hardware framebuffer
drivers furthermore from the SDL framebuffer driver used by Genode/Linux.

da2076e52a usb: fix support for HID keyboard
This fixes issues with several HID keyboards by implementing
get_unaligned_le16(), which obviously may also fix other not-yet-known
issues. Hint: I had to look out for suspicious lines like follows in the
verbose log.

  [init -> usb_drv] get_unaligned_le16 called, not implemented

Also, quirks for cherry keyboards are now applied.

1730132ef1 usb: fix linux header include setup phase
In usb.inc all required Linux include files of the Linux code are looked up
by 'sed'ing through the files of SRC_C and SRC_CC. The Linux include files
are then added as dependency to the SRC_C and SRC_CC files and during dependency
resolution symbolic links to the lx_emul.h will be created.

In the platform specific usb.mk file there are the Linux driver files
added, but unfortunately after including usb.inc. So, for them no dependency
to any Linux include header file is generated and so no symbolic files are
generated.

If the driver code file is compiled as first, as for asix.c, the symbolic links
of the include files are missing and compilation fails.

Add the Linux driver code files to SRC_C before including usb.inc in the
platform specific usb.mk files.

fae63f4fa9 Merge base libraries into a single library
This patch simplifies the way of how Genode's base libraries are
organized. Originally, the base API was implemented in the form of many
small libraries such as 'thread', 'env', 'server', etc. Most of them
used to consist of only a small number of files. Because those libraries
are incorporated in any build, the checking of their inter-dependencies
made the build process more verbose than desired. Also, the number of
libraries and their roles (core only, non-core only, shared by both core
and non-core) were not easy to capture.

Hereby, the base libraries have been reduced to the following few
libraries:

- startup.mk contains the startup code for normal Genode processes.
  On some platform, core is able to use the library as well.
- base-common.mk contains the parts of the base library that are
  identical by core and non-core processes.
- base.mk contains the complete base API implementation for non-core
  processes

Consequently, the 'LIBS' declaration in 'target.mk' files becomes
simpler as well. In the most simple case, only the 'base' library must
be mentioned.

af66043b79 New Input::Event::FOCUS, rename keycode to code
This patch introduces keyboard-focus events to the 'Input::Event' class
and changes the name 'Input::Event::keycode' to 'code'. The 'code'
represents the key code for PRESS/RELEASE events, and the focus state
for FOCUS events (0 - unfocused, 1 - focused).

Furthermore, nitpicker has been adapted to deliver FOCUS events to its
clients.

9dae5ee490 USB: Use real HID driver in dde_linux

13d4108fea Unify 'Signal_dispatcher' interfaces
Several users of the signal API used custom convenience classes to
invoke signal-handling functions on the reception of incoming signals.
The 'Signal_dispatcher' pattern turned out to be particularly useful. To
avoid the duplication of this code across the code base, this patch
adds the interface to 'base/signal.h'.

Furthermore, the patch changes the 'Signal::num()' return type from int
to unsigned because negative numbers are meaningless here.

0dbb5e1696 Propagate 'Range_allocator::alloc_aligned' errors
This patch reflects eventual allocation errors in a more specific way to
the caller of 'alloc_aligned', in particular out-of-metadata and
out-of-memory are considered as different conditions.

Related to issue #526.

cfa0a40d5e base_hw & omap4: USB HID and framebuffer driver.
Implement 'Signal_receiver::pending()'.

Provide display-subsystem MMIO.

Avoid method ambiguousness in 'Irq_context' in
'dde_linux/src/drivers/usb/signal/irq.cc'
(it derives from two list element classes when using 'base_hw').

Enables demo scenario with 'hw_panda_a2'.

d3902e8538 Make nic_bridge's MAC address range configurable
By adding a "mac=XX:XX:XX:XX:XX:XX" attribute/value pair to the nic_bridge's
configuration one can define the first MAC address from which the nic_brigde
will allocate MACs for it's clients. Note: that the least relevant byte will
be ignored, and ranges from 0-255. Fixes #424.

3e406a1077 Increase quota of USB driver
The memory allocation heuristics in the usb driver provided by dde_linux
changed with the recent commit 71b2b42936.
Apparently, the new variant requires a larger memory pool. Increasing
the quota is a temporary fix until the memory allocator gets revisited.

c98a80251c USB: Sync interrupts
On systems that use multiple UHCI/EHCI controllers, synchronize access to low
level interrupt handler. Let 'device_may_wakeup' return 1, so suspended
controllers will send interrupts upon device connection. Make sure URBs are
shutdown upon disconnect.

3207b4eed0 USB: Performance improvements
Added SKB bitmap allocator, use Nic::Packet_allocator in packet stream, use slab
allocators on top of back-end AVL allocator, split allocators in cached/uncached
for general purpose/DMA allocation, added patch to original code to distinguish
cached or uncached memory requests, take advantage of and implement TX bursts
(or SKB batching), call interrupt handlers until they return unhandled.

e1435a3f57 Replace old test/block with test/ahci
The block test at test/ahci is indeed not AHCI-specific. It is a generic
block read/write test for the block-session interface. But in contrast
to the original test/block, it restores the block device content (at
least when the test succeeds). Hence, we remove the original (dangerous)
block test and always use code of test/ahci.

9f73476b37 New DDE-Linux-based USB driver
The new 'dde_linux' repository will host device drivers ported from the
Linux kernel. In contrast to the original 'linux_drivers' repository,
'dde_linux' does not contain any 3rd-party source code. To download the
Linux kernel source code and extract the drivers, execute the 'make
prepare' rule of the top-level Makefile. The initial version of the
'dde_linux' repository comes with an USB driver. The porting methodology
follows the path of the Intel GEM port. Instead of attempting to provide
a generic Linux environment that works across drivers, each driver comes
with a specially tailored DDE.

The DDE consists of Genode-specific implementations of Linux API
functions as declared in 'lx_emul.h'. Most of these functions are
dummies that must merely be provided to resolve dependencies at the
linking stage. They are called by unused code-paths.

As of now, the USB driver support UHCI, EHCI on the x86_32 platform. I
exposes USB HID devices and USB storage devices via Genode's input-session
and block-session respectively.

The USB driver is accompanied with two run scripts 'run/usb_hid.run' and
'run/usb_storage.run'.
