[U-Boot] [PATCH v7 1/4] Exynos: Clock.c: Use CONFIG_SYS_CLK_FREQ macro

Chander Kashyap chander.kashyap at linaro.org
Thu Feb 2 10:11:24 CET 2012


CONFIG_SYS_CLK_FREQ_C210 macro giving notion of S5PC2XX (Exynos4)
architecture. Replace CONFIG_SYS_CLK_FREQ_C210 with CONFIG_SYS_CLK_FREQ
to make it generic for exynos architecture.
