Instead of holding SPEC-variable dependent files and directories inline within the repository structure, move them into 'spec' subdirectories at the corresponding levels, e.g.: repos/base/include/spec repos/base/mk/spec repos/base/lib/mk/spec repos/base/src/core/spec ... Moreover, this commit removes the 'platform' directories. That term was used in an overloaded sense. All SPEC-relative 'platform' directories are now named 'spec'. Other files, like for instance those related to the kernel/architecture specific startup library, where moved from 'platform' directories to explicit, more meaningful places like e.g.: 'src/lib/startup'.

================================
Genode's Rump Kernel kernel port
================================
This repository contains the Genode version of the [http://wiki.netbsd.org/rumpkernel/ - rump kernel].
The kernel is currently used to gain file-system access from within Genode. In
order to achieve that, a Genode file-system server is located at
_src/server/rump_fs_. For accessing the server through the libc, the _libc_fs_
plugin can be facilitated, which is available in the _libports_ repository.
Building instructions
#####################
In order to build the file-system server, issue
! make prepare
from the directory this file is contained in.
Add
! REPOSITORIES += $(GENODE_DIR)/repos/dde_rump
to your _etc/build.conf_ file of you build directory.
Finally,
! make server/rumps_fs
called from your build directory will build the server. You may also specify
! make run/rump_ext2
to run a simple test scenario.
Configuration
#############
Here is an example snippet that configures the server:
!<start name="rump_fs">
! <resource name="RAM" quantum="8M" />
! <provides><service name="File_system"/></provides>
! <config fs="ext2fs"><policy label="" root="/" writeable="yes"/></config>
!</start>
The server is looking for a service that provides a Genode block session. If
there is more than one block session in the system, the block session must be
routed to the right block-session server. The value of the _fs_ attribute of
the _config_ node can be one of the following: _ext2fs_ for EXT2, _cd9660_ for
ISO-9660, or _msdos_ for FAT file-system support. _root_ defines the directory
of the file system as seen as root directory by the client. The server hands
most of its RAM quota to the rump kernel. This means the larger the quota is,
the larger the internal block caches of the rump kernel will be.
