7f2f2d9120 base-hw: ease core build
Merge core only libs into the target make-files.

Use base-hw specific Board drivers that inherit
from generic Board_base.

Use Page_flags::access_t instead of additional
page_flags_t.

4dadd6a437 base-hw: Read and write whole thread states.
By now there is no use case for read/write a single register
of a thread state. Thus the new syscalls 'read_thread_state' and
'write_thread_state' replace the old ones 'read_register' and
'write_register'.

6cb89f79e3 base_hw & arm_v7: Use write-back caching.
Add 'resume_faulter' syscall that is similar to 'resume_thread', but
is called only when resuming a thread after resolving its pagefault.
This way the kernel can flush caches after resolving a pagefault. This is
because by now the MMU doesn't use caches when doing a pagetable walk.

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.

Related to #510.

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'.

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.

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.

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.
