Rename xilinx_zynqmp_rpu BSP variant to zynqmp_rpu_lock_step to
emphasize that this BSP is for the lock-step mode RPU configuration.
Add BSP variants zynqmp_rpu_split_0 and zynqmp_rpu_split_1 for the split
mode RPU configuration for core 0 and 1 respectively.
Make the clock driver parameters configurable. Use the maximum counter
frequency to get the best time resolution. Decouple the CPU counter from the
timecounter. Make the tick catch up handling more robust. Add a validation
test for the tick catch up.
Pass the parameter of the clock interrupt handler to
Clock_driver_support_at_tick() and Clock_driver_timecounter_tick(). This makes
it possible to use the interrupt handler argument in clock drivers.
Use the interrupt handler provided by Clock_driver_support_install_isr() to
avoid local delarations of Clock_isr().
Update #4862.
We observed a strange behavior of the 1Hz timer when running cFS on Zynq
RPU. After some investigation, we reduced the error to the truncation
issue. This patch fixes the issue.
