Accesses to the L2C registers performed by the L2C driver are now
serialized with spin locks. This avoids concurrent access to the L2C
registers by multiple processors. Proposed by GRLIB-TN-0021.
Update #4925.
This updates the implementation of the LEON3 processor power-down
function.
It now contains the workaround for the GR712RC power-down errata
described in GR712RC-UM, version 2.16, section 1.7.8. The workaround is
compatible with other LEON3/LEON4 components.
Update #4875.
Properly serialize explicit thread priority changes (for example
rtems_task_set_priority()) and thread priority changes carried out by
thread queues (locking protocols such as priority inheritance).
Update #5159.
Test the proper serialization of explicit thread priority changes (for
example rtems_task_set_priority()) and thread priority changes carried
out by thread queues (locking protocols such as priority inheritance).
With RTEMS_DEBUG enabled, the new test case fails with an assertion. It
is fixed in a follow up commit.
Update #5159.
Change the time to convert so that rounding issues do not propergate to
the second next digit. Properly round the result used for the precision
estimate.
The two RTCs supported by that driver (MCP7940M and EOZ9) use slightly
different register order. Add support for a different order to the
i2c-rtc driver.
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.
