The platform driver is used to access the features provided by the
Videocore mboxes, i.e., power configuration and framebuffer setup. The
framebuffer driver uses the platform interface to setup a screen mode of
1024x768.
At the current stage, the USB HID and storage drivers are prinicpally
working but not stable. If interrupts are not processed fast enough,
devices will get sporadically disconnected.
The USB host-controller driver is not part of the normal Linux kernel.
For this reason, we need to download it separately. There exists a
'prepare_rpi' rule in the 'dde_linux/Makefile' to automate this process.
Provide core-local signal service before other services to enable the use
of signal connections while initialzing the other services. This has been
introduced due to the use of the signal framework by the pager lib in
base-hw (RM service).

The copy constructor of Signal did not copy the Signal::Data contents of
the copy source. This bug could survive undetected because the compiler
can optimize code in a way, that copy constructor and destructor are not
necessary when returning by value from simple functions. I assume that
it creates the object in CPU registers instead of RAM and reuses it
instead of copying it to save time. This way the bug triggered first
after wait_for_signal was changed in a way that avoided optimization.
ref #912
The new 'String' buffer type is meant to replace the manually created
character buffers that are scattered throughout Genode. It plainly holds
a null-terminated string to be stored as a member variable (e.g., a
session label) or passed as RPC argument. It is not intended to become a
string API.
To prevent multiple execution of main-bootstrap, I moved the code to a
statically initialized object. The reason for this change is that
_main() is exeuted twice when starting dynamic binaries. Now, the object
is part of the base-common library which is linked with ld.lib.so.
Originally, the convenience utility for accessing a process
configuration came in the form of a header file. But this causes
aliasing problems if multiple compilation units access the config while
the configuration gets dynamically updated. Moving the implementation of
the accessor to the singleton object into a library solves those
problems.
