570156b38c l4lx: allocate memory in chunks
When L4Linux tries to allocate a dataspace of the size of its physical
memory, this allocation can fail, because the 'l4re_ma_alloc()' function
in the 'l4lx' library always tries to allocate a contiguous dataspace of
the given size and there might be no contiguous free area left.

With this patch, memory gets allocated in chunks: if the size to be
allocated exceeds the configured chunk size, a managed dataspace gets
created and filled with multiple memory chunks of at most the chunk size.

The chunk size is 16M by default and can be configured in an l4linux
config node:

<config args="...">
	<ram chunk_size="16M"/>
</config>

Fixes #695.

3ae2c1712e base-foc: Do not touch memory during map operation
Don't do anything in Mapping::prepare_map_operation.  At this point and in the
current implementation, the memory has been mapped and cleared already. Touching
the memory may only pollute the cache causing data corruption in DMA memory.

Fixes issue #452

452624e1a6 Fiasco(.OC) KDB UART driver
The KDB UART driver uses the Fiasco(.OC) kernel debugger console as backend
for input and output. This is useful in the case that only one UART is
available.

b8eb9b534d Switch to Seoul VMM repository instead of NUL
In this version of the transition the Hip structure from Genode is reused,
@nfeskes seoul_libc_support is used for the string functions and the
nul/config.h is replaced by just using a constant value in the one place where
the file was needed.

b38fee2867 L4Linux stability improvements
- search for alternative virtual address regions upwards, starting from
  the given start address, in the 'l4re_rm_attach()' and
  'Region_manager::reserve_range()' functions

- don't treat memory locations above 0x80000000 in l4linux's virtual
  address space as device memory

- align the start address of the vmalloc area according to the assumption
  in 'devicemaps_init()'

ce58a63fb6 Remove 'epit' from generic i.MX platform spec
Remove the 'epit' variable from the generic imx31 and imx53 specification,

Moreover, fix some const-ness issues in the platform_timer implementation
for the EPIT timer.

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.

38b2a3dbb4 nova: support to run script automatically with AMT
This enables us to use the run scripts applied to a native machine equipped
with Intel's AMT. If the environment variables are correctly set up, the remote
test machine is reseted via 'amttool', then via 'amtterm' the serial output
is collected and the normal run script matching pattern for success/failure of
the run script are applied.

'amttool' and 'amtterm' are part of the package called 'amtterm' shipped with
the Linux distributions like Ubuntu, Debian and lot more.

Following environment variables are required, to run the run scripts with a
native AMT test machine:

PXE_TFTP_DIR_BASE   - absolute path of TFTP directory
PXE_TFTP_DIR_OFFSET - relative path to PXE_TFTP_DIR_BASE where the config file
                      will be generated - named 'config-00-00-00-00-00-00'

AMT_TEST_MACHINE_IP  - TCP/IP address of target AMT test machine
AMT_TEST_MACHINE_PWD - password of target AMT test machine

6f2e36279a Use mkisofs to create ISO images
mkisofs is the original ISO creation tool from cdrtools available on
many UNIX systems. genisoimage on the other hand is part of a mostly
unmaintained fork of cdrtools very specific to Debian Linux and its
derivates (e.g., Ubuntu). Fortunately, genisoimage (as we used it) is
completely invocation-compatible to mkisofs.
