While working on the bootstage support for Armada XP (orion-timer) I noticed, that we currently have two API's supporting early timer functionality. These are:
a) timer_early_get_rate() & timer_early_get_count() which integrates into the "normal" timer functions like timer_get() & timer_get_us() in the early boot phase, if CONFIG_TIMER_EARLY is enabled b) timer_get_boot_us(), which was introduced with bootstage IIUTC
IMHO it makes more sense to not introduce a new API for this early timer functionality but re-use the "normal" API instead. This patchset migrates the timer_get_boot_us() implementations to the timer_early functions. This is done by:
- Implementing the timer_early functions in the drivers currently supporting timer_get_boot_us() - Migrating bootcount to using timer_get_us() instead of timer_get_boot_us() - Completely removing timer_get_boot_us()
With some minor tweaks in board_r/f for the dm_timer_init() and timer_init() call.
I've tested this on Armada XP and sandbox.
Thanks, Stefan
