TFTP server requiring absolute directory names are supported (better) -
specify in RUN_OPT "--tftp-absolute" to create Pulsar config with absolute
path names for PXE boot.
Additional a symbolic link is created from the build directory to
"$PXE_TFTP_DIR_BASE$PXE_TFTP_DIR_OFFSET" automatically. This eases the use
together with autopilot for x86.
If the target machine is connected locally one may specify
"serial" as target in the RUN_OPT variable to get the test output.
Used for panda and arndale on foc and hw.
genode_until_run can be called now with a spawn id to able to reattach to a
spawned process (amt, serial output). Run scripts can now call genode_until_run
multiple times.
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.
Fixes#665.
Eliminate prints to stderr for normal messages, because it leads to exceptional
returns in TCL-scripts e.g. when run-script is triggered by the autopilot even
if the script's return code itself will be zero.
When invoking the bootstrap build in the L4RE build-system to create
a single elf-image containing all needed files to boot a scenario, don't
use the 'ENTRY' variable, but 'E' variable instead. Otherwise 'ENTRY'
might get overridden (dependent on the make-version). Moreover, using
'E' seems to be the way L4Re is expecting it has to be invoked.
Fixes#226
