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.

f2d81a8d62 Remove superfluous, generic Thread_state definition
The 'Cpu_state' in 'base/include/base/cpu_state.h' is not needed anymore.
Moreover, it's inconsistent with the architecture-specific definitions
of 'Cpu_state' that all reside in <cpu/cpu_state.h>.

6cd0c02dcd base-hw: introduce VM session interface

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.

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.

1c064d9e70 core: implement missing context area functions
This patch implements the following functions:

base:
- Context_area_rm_session::detach()
- Context_area_ram_session::free()

base-nova:
- unmap_local()

base-fiasco, base-pistachio:
- unmap_local() stub

This patch partially resolves issue #394.

837f913094 Noux: more useful gettimeofday() implementation
There are certain programs that need gettimeofday(), e.g.
network-related tools like ping(1) etc. but also filesystem-related
programs like find(1) etc. and of course time-related programs like
date(1).

As there is currently no interface in Genode for actually using clock
devices like RTC on x86 (though there is a driver for it) we "abuse"
the timeout_scheduler thread to at least provide flow-of-time.

Noux: add clock_gettime() implementation

For now, only CLOCK_SECOND is supported.

Noux: add utimes() dummy

17dc60eb66 cxx: make 'operator delete(void *)' a weak symbol
The 'delete (void *)' operator gets referenced by compiler generated code,
so it must be publicly defined in the 'cxx' library. These compiler
generated calls seem to get executed only subsequently to explicit
'delete (void *)' calls in application code, which are not supported by
the 'cxx' library, so the 'delete (void *)' implementation in the 'cxx'
library does not have to do anything. Applications should use the
'delete (void *)' implementation of the 'stdcxx' library instead. To make
this possible, the 'delete (void *)' implementation in the 'cxx' library
must be 'weak'.

Fixes #419.

a287831537 L4Linux: dimension block cache correctly (fix #426)
In Genode's paravirtualized block driver a request cache is used to find again
Linux request structures via corresponding block-session packets. To work
correctly the cache needs to have at least the same size like the
block-session's queue-size.

4a3d852b65 Core: Shared IRQ support for Nova/FOC/OKL4
Implement shared IRQs using 'Irq_proxy' class.

Nova: Added global worker 'Irq_thread' support in core and adapted Irq_session.

FOC: Adapted IRQ session code, x86 has shared IRQ support, ARM uses the old
model. Read and set 'mode' argument (from MADT) in 'Irq_session'.

OKL4: Use generic 'Irq_proxy'

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.
