From 207774b213caa3c72ebd6c9f6d1e4a3a666938b7 Mon Sep 17 00:00:00 2001 From: York Sun Date: Fri, 20 Mar 2015 19:28:08 -0700 Subject: armv8/ls2085a: Fix generic timer clock source The timer clock is system clock divided by 4, not fixed 12MHz. This is common to the SoC, not board specific. Primary core is fixed when u-boot still runs in board_f. Secondary cores are fixed by reading a variable set by u-boot.
