The RTEMS_UNREACHABLE() is a hint to the compiler that this code
location is unreachable. The compiler may use this information to
optimize the code. If a test case fails and we reach this code
location, then unpredictable things may happen making the test case
debugging more difficult than necessary.
In case of overflows, we may have an RTEMS_RECORD_UPTIME_HIGH event as
the first event. This uptime high event has no associated
RTEMS_RECORD_UPTIME_LOW event.
This code had a uint32_t local variable for seconds from a timespec.
This was assigning a time_t to a uint32_t and ultimately returning it.
This propgated to rtems_timespec_add_to().

Closes#5107.
The updated waf version deletes the waf cache directory in the build
tree. This removes also the build specification item cache. Move the
cache directory so that it works across configure commands.
The devfg driver loads the PL with a bitfile image. The driver can also
support scrubbing.
These drivers are from Patrick Gauvin <pggauvin at gmail.com> and a thread
on the devel list: https://lists.rtems.org/pipermail/devel/2017-May/017705.html
When using QEMU configurations that support SMP for Zynq7000 systems,
the second core is started at the same time as the first core instead of
waiting for an event to trigger a check for the value at 0xfffffff0
before jumping into RTEMS code. This makes the erroneously started core
wait as expected and prevents prefetch and data aborts from occurring
before the MMU has been properly configured. This was recently exposed
by cleanup done to the ARM GICv2 driver that removed some delays which
were allowing this to operate normally.
The general optclkbootcpu option is targeted at all ARM QEMU BSPs, but
is not actually linked in to the build tree. This links it in as
expected and removes a redundant and stale copy in the realview PBX BSP.
The RT_TSW_OK field is set to 1 if there was no error. The Message Error
(ME) field indicates an error and must be set to 0 if there was no error
so the result of tsw&RT_TSW_OK must be negated. It is then left-shifted
to the Messsage Error (ME) bit field of the message information word.
Fix issue CID 1399772
This removes the headers imported from the embeddedsw repository in
favor of a much thinner shim. This also removes the complicated build
system configuration necessary to support use of these headers. The
primary reason for removal is that certain external Xilinx libraries
also require use of these headers and this causes version mismatches and
header conflicts that can be avoided.
