[PATCH v2 0/9] sparc: Simplify clock drivers and CPU counter

[Sebastian Huber]

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
