This patch set simplifies the clock drivers and CPU counter
implementations of the sparc BSPs. For the GR712RC the Debug Support
Unit (DSU) is used as a performance optimization.
v2:
Improve code clarity.
Sebastian Huber (9):
bsps/leon3: Optional IRQ(A)MP timestamp support
sparc: Move CPU counter implementation
bsps/leon3: Make GPTIMER fall back mandatory
bsps/leon3: Simplify clock and CPU counter
bsps/leon3: Use custom CPU counter implementation
bsps/leon3: Move code blocks
bsps/leon3: Statically initialize get timecount
bsps/leon3: leon3_counter_use_irqamp_timestamp()
bsps/leon3: Use DSU time tag for GR712RC
