From: Wang Huan <b18965@freescale.com>

The QorIQ LS1 family is built on Layerscape architecture,
the industry's first software-aware, core-agnostic networking
architecture to offer unprecedented efficiency and scale.

Freescale LS102xA is a set of SoCs combines two ARM
Cortex-A7 cores that have been optimized for high
reliability and pack the highest level of integration
available for sub-3 W embedded communications processors
with Layerscape architecture and with a comprehensive
enablement model focused on ease of programmability.

Dear Alison Wang,

In message <1409895853-17736-2-git-send-email-alison.wang@freescale.com> you wrote:

I think this should be simplified into a

	#ifndef CONFIG_DDR_CLK_FREQ
	#define CONFIG_DDR_CLK_FREQ	CONFIG_SYS_CLK_FREQ
	#endif

somewhere in a header file, and getting rid of the #ifdef here?


Best regards,

Dear Wolfgang,

I prefer to stay this way. In the past for mpc85xx, DDR clock source could come
from a dedicated clock, or from the system clock. If it comes from the dedicated
clock, different care is needed to calculate the DDR ratio. This SoC may go that
path as well.
