Subject: ARM: HYP/non-sec: Fix the ARCH Timer frequency setting.
X-Git-Tag: v2015.01-rc4~29^2~7
X-Git-Url: https://git.librecmc.org/?a=commitdiff_plain;h=73a1cb27c0d9e93d97cd7a344fd341f638ba3a2a;p=oweals%2Fu-boot.git
ARM: HYP/non-sec: Fix the ARCH Timer frequency setting.
For some SoCs, the system clock frequency may not equal to the
ARCH Timer's frequency.
This patch uses the CONFIG_TIMER_CLK_FREQ instead of
CONFIG_SYS_CLK_FREQ, then the system clock macro and arch timer
macor could be set separately and without interfering each other.
