Subject: armv7: timer: init timer with bootstage
X-Git-Url: http://git.dujemihanovic.xyz/?a=commitdiff_plain;h=c596877ee6e8f235b6d6a8e0d4a9366ce086a3ed;p=u-boot.git

armv7: timer: init timer with bootstage

In initf_bootstage() we call bootstage_mark_name() which ends up calling
timer_get_us() before timer_init(); that cause crash for stm32mp1.

This patch solve the issue without changing the initialization sequence.
See also commit 97d20f69f53e ("Enable CONFIG_TIMER_EARLY with bootstage")
for other solution when DM is activated for TIMER.
