Subject: sh: tmu: Zap get_tbclk and timer_read_counter
X-Git-Tag: v2018.11-rc1~120^2~1
X-Git-Url: https://git.librecmc.org/?a=commitdiff_plain;h=0e286c529f395947dbb96da93081883aca40a57f;p=oweals%2Fu-boot.git

sh: tmu: Zap get_tbclk and timer_read_counter

Replace those two functions with generic ones by defining the
timer macros in include/config/*.h .
