371b8fd12d Remove mirroring of 'lx_rpath' in 'app/chroot'
Thanks to the exclusive use of SCM rights for delegating access rights
to memory objects and RPC entrypoints, Genode processes outside of core
won't need to access any files.

06ce0a8ef1 loader: Fix warnings about uninitialized variable
g++ 4.4.5 outputs the following warnings in our code using the loader
session:

.../base/include/base/capability.h: In member function 'typename Genode::Trait::Call_return<typename IF::Ret_type>::Type Genode::Capability<RPC_INTERFACE>::call() const [with IF = Loader::Session::Rpc_view_geometry, RPC_INTERFACE = Loader::Session]':
.../base/include/base/capability.h:207: warning: 'ret.Genode::Capability<Loader::Session>::Return<Loader::Session::Rpc_view_geometry>::_value.Loader::Session::View_geometry::width' may be used uninitialized in this function
.../base/include/base/capability.h:207: warning: 'ret.Genode::Capability<Loader::Session>::Return<Loader::Session::Rpc_view_geometry>::_value.Loader::Session::View_geometry::height' may be used uninitialized in this function
.../base/include/base/capability.h:207: warning: 'ret.Genode::Capability<Loader::Session>::Return<Loader::Session::Rpc_view_geometry>::_value.Loader::Session::View_geometry::buf_x' may be used uninitialized in this function

This is easily fixed with providing a default constructor.

Because of the C++ rules regarding initialer lists code that used
them for View_geometry had to be modified to use a normal construction
call.  In my tests only Nitpicker had to be changed.

94ea3a0acb Move away drivers from generic base-repository
Driver definitions which are used by kernel/core in base-hw, and also by other
drivers (e.g. from the os repository) have to reside in the generic
base-repository, for instance some uart drivers. All drivers which are
interesting for one of the sites only (sp804 for timer driver, or
cortex_a9 cpu driver for base-hw) should reside in the respective repos.

Factorize cpu context out of Cortex A9 specific definitions. Moreover, there
is already a Cpu_state object containing all common ARM registers. We use
this as a base for the cpu context switching done by the base-hw kernel.
The Cpu_state class get extended by a cpu-exception field, that stores the kind
of exception raised when the corresponding context got interrupted. This
information is used not only by the base-hw kernel, but also by the TrustZone
VMM that is build currently.

96d45c1159 Define board declarations in a more generic fashion
By naming all board declaration (previously in base/include/drivers/board) the
same way, and putting them in platform-specific include-pathes, we save additional
declaration redirection in the base-hw kernel, and in driver definitions.

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.

64245dde3a Avoid superfluous compiler warnings
GCC warns about uninitialized local variables in cases where no
initialization is needed, in particular in the overloads of the
'Capability::call()' function. Prior this patch, we dealt with those
warnings by using an (unreliable) GCC pragma or by disabling the
particular warning altogether (which is a bad idea). This patch removes
the superfluous warnings by telling the compiler that the variable in
question is volatile.

6862ab481a NOVA: drop special utcb handling of main thread
Unify handling of UTCBs. The utcb of the main thread is with commit
ea38aad30e at a fixed location - per convention.
So we can remove all the ugly code to transfer the utcb address during process
creation.

To do so also the UTCB of the main thread of Core must be inside Genode's
thread context area to handle it the same way. Unfortunately the UTCB of the
main thread of Core can't be chosen, it is defined by the kernel.

Possible solutions:
- make virtual address of first thread UTCB configurable in hypervisor
- map the utcb of the first thread inside Core to the desired location

This commit implements the second option.

Kernel patch: make utcb map-able
With the patch the Utcb of the main thread of Core is map-able.

Fixes #374

Noux actually uses the sp variable during thread creation and expects to be
set accordingly. This wasn't the case for the main thread, it was ever set
to the address of the main thread UTCB.

5c36639031 Fix UDP checksum calculation (fixes #360)
Missing parantheses around the calculation of last byte address in a UDP
Packet led to dereferencing the wrong value, thereby the UDP checksum
calculation failed, whenever an odd byte-count UPD packet was calculated.
Many thanks to Markus Partheymueller who discovered this issue and its
resolution.

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.

9651974448 Add stdcxx-4.6.1 to libports, fix #339
This patch adds libstdc++ to libports. With the previous version of the
stdcxx library, the build system used the C++ standard library that
comes with the compiler. This mechanism was prone to inconsistencies of
types defined in the header files used at compile time of the tool chain
and the types provided by our libc. By building the C++ standard library
as part of the Genode build process, such inconsistencies cannot happen
anymore.

Note that the patch changes the meaning of the 'stdcxx' library for
users that happened to rely on 'stdcxx' for hybrid Linux/Genode
applications. For such uses, the original mechanism is still available,
in the renamed form of 'toolchain_stdcxx'.

47ef3bb1cb NOVA: Fix ldso test for 64bit
The generic parent_cap.cc overwrote the beginning of the data segment with
to much. Reserved are solely 16 byte, for 64bit we use however 32byte.

Actually, the parent_cap copying is not required at all. The parent cap
selector is at a fixed define place, so that no exported symbols are required
for determination of the parent_cap.

Remove it.

7e0a1cc0eb Allocate DMA buffer for block packet stream
By allocating the packet-stream dataspace for block sessions as
uncached, we can use DMA to directly read and write into the client
buffer. Currently, the OMAP4 SD-card driver is using this feature.

0f6110ea97 Let OMAP4 SD-card driver use DMA and interrupts
With this patch, the driver code gets complemented with DMA support.
The support for master DMA, in turn, cleared the way for using
interrupts to wait for the completion of transfers, which largely
relieves the CPU compared to the polling PIO mode. Consequently, the new
version has a much lower CPU footprint.

In the current version, both modes of operation PIO and DMA are
functional. However, PIO mode is retained for benchmarking purposes only
and will possibly be removed to keep the driver simple. It is disabled
in the driver's 'main.cc'.

e9497a183f Improve measurement accuracy
This patch replaces the jiffies thread in 'sd_card/omap4/bench' calls to
'Timer::Session::elapsed_ms()'. This way, we use wall-clock time for the
measurements. Depending on the load of the rest of the system, the
previous version used to accumulate the inaccuracy for each 'msleep'
call.
