bb00aebc9e hw & signal: consider initial SLAB blocks
By now Signal_session_component has allocated initial SLAB
blocks in constructor, wich crashed with the root
components assumptions about the RAM quota needs of
session creation. Thus, if the background allocator was already
exhausted from component allocation the session was created
with broken initial SLAB blocks.

5fe29e8e4a Express affinities via Cartesian coordinates
This patch introduces new types for expressing CPU affinities. Instead
of dealing with physical CPU numbers, affinities are expressed as
rectangles in a grid of virtual CPU nodes. This clears the way to
conveniently assign sets of adjacent CPUs to subsystems, each of them
managing their respective viewport of the coordinate space.

By using 2D Cartesian coordinates, the locality of CPU nodes can be
modeled for different topologies such as SMP (simple Nx1 grid), grids of
NUMA nodes, or ring topologies.

e717ad656f base-hw: preserve symbolic link bin/core
In this case "mv A B" works slightly different than "cp A B; rm A" as
symbolic links come into play. The statements should copy the contents
of A into the symboliv link at B (preserving it as is) and remove A. The
mv would replace the link B by the binary A.

21de42c45d core: Introduce 'Address_space' interface
The new core-internal 'Address_space' interface enables cores RM service
to flush mappings of a PD in which a given 'Rm_client' thread resides.
Prior this patch, each platform invented their own way to flush mappings
in the respective 'rm_session_support.cc' implementation. However, those
implementations used to deal poorly with some corner cases. In
particular, if a PD session was destroyed prior a RM session, the RM
session would try to use no longer existing PD session. The new
'Address_space' uses the just added weak-pointer mechanism to deal with
this issue.

Furthermore, the generic 'Rm_session_component::detach' function has
been improved to avoid duplicated unmap operations for platforms that
implement the 'Address_space' interface. Therefore, it is related to
issue #595. Right now, this is OKL4 only, but other platforms will follow.

a99193ad90 Rework the internal lock interface
With this patch, the 'futex' syscall gets used for blocking and unblocking
of threads in the Linux-specific lock implementation.

The 'Native_thread_id' type, which was previously used in the
lock-internal 'Applicant' class to identify a thread to be woken up,
was not suitable anymore for implementing this change. With this patch,
the 'Thread_base*' type gets used instead, which also has the positive
effect of making the public 'cancelable_lock.h' header file
platform-independent.

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.

bcdc706f42 Unify 'ipc.h' and 'ipc_generic.h' across platforms
The distinction between 'ipc.h' and 'ipc_generic.h' is no more. The only
use case for platform-specific extensions of the IPC support was the
marshalling of capabilities. However, this case is accommodated by a
function interface ('_marshal_capability', '_unmarshal_capability'). By
moving the implementation of these functions from the headers into the
respective ipc libraries, we can abandon the platform-specific 'ipc.h'
headers.

959df5d46b Generalize handling of PD-session arguments
On Linux, we want to attach additional attributes to processes, i.e.,
the chroot location, the designated UID, and GID. Instead of polluting
the generic code with such Linux-specific platform details, I introduced
the new 'Native_pd_args' type, which can be customized for each
platform. The platform-dependent policy of init is factored out in the
new 'pd_args' library.

The new 'base-linux/run/lx_pd_args.run' script can be used to validate
the propagation of those attributes into core.

Note that this patch does not add the interpretation of the new UID and
PID attributes by core. This will be subject of a follow-up patch.

bcabbe2c92 Add 'Thread_base::join()'
Using the new 'join()' function, the caller can explicitly block for the
completion of the thread's 'entry()' function. The test case for this
feature can be found at 'os/src/test/thread_join'. For hybrid
Linux/Genode programs, the 'Thread_base::join()' does not map directly
to 'pthread_join'. The latter function gets already called by the
destructor of 'Thread_base'. According to the documentation, subsequent
calls of 'pthread_join' for one thread may result in undefined behaviour.
So we use a 'Genode::Lock' on this platform, which is in line with the
other platforms.

31d57a6257 Nested init on i.MX31 via base_hw. Rework base_hw.
Implies support for the ARMv6 architecture through 'base-hw'.

Get rid of 'base/include/drivers' expect of 'base/include/drivers/uart'.

Merge with the support for trustzone on VEA9X4 that came from
Stefan Kalkowski.

Leave board drivers in 'base/include/platform'.

Rework structure of the other drivers that were moved to
'base_hw/src/core' and those that came with the trustzone support.

Beautify further stuff in 'base_hw'.

Test 'nested_init' with 'hw_imx31' (hardware) and 'hw_panda_a2' (hardware),
'demo' and 'signal' with 'hw_pbxa9' (qemu) and 'hw_vea9x4'
(hardware, no trustzone), and 'vmm' with 'hw_vea9x4'
(hardware, with trustzone).

8393ac6895 base-hw: implement vm_session for TrustZone
* Introduces Schedule_context
* Use fast-interrupts or normal interrupts
* Add mode-transition between secure/non-secure world
* Limit system resources for Genode apps due to non-secure world

This commit implements the newly introduced Vm session interface to be used
on top of TrustZone capable Armv7 CPUs. Therefore a new Schedule_context is
introduced in the kernel. Threads and Vms are both Schedule_contexts used
by the scheduler. In contrast to a thread a vm uses a different assembler
mode switch to the non-secure, virtual world, as well as another exception
is used, when the non-secure world is left. For both worlds to co-exist
the interrupt-controller needs to be configured, so that the secure (Genode)
world uses fast-interrupts only, and the non-secure world only legacy
interrupts.
The only TrustZone capable platform the base-hw kernel works on top of
is the CoreTile Express 9x4 for the Versatile Express motherboard. For a
virtual machine working properly on top some platform resources must be
reserved. Therefore there exist two flavours of this platform now, one with
the 'trustzone' spec-variable enabled, and one without. If 'trustzone' is
specified most platform resources (DDR-RAM, and most IRQs) are reserved
for the Vm and not available to the secure Genode world.

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.

6cd0c02dcd base-hw: introduce VM session interface
The VM session interface is meant to be generic, but first will be used in the context
of TrustZone only.

dc3d784e6d Introduce platform-specific services for core
By now all services in core where created, and registered in the generic
main routine. Although there exists already a x86-specific service (I/O ports)
there was no possibility to announce core-services for certain platforms only.
This commit introduces a hook function in the 'Platform' class, that enables
registration of platform-specific services. Moreover, the io-port service
is offered on x86 platforms only now.

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.
