咨询6657的spi nor flash加载的ddr table

各位大神：

我的6657双核加载起来了 但没使用DDR TABLE

想咨询一下6657的DDR TABLE如何添加？
我看6657的文档 没有提到任何有关ddr configuration table的资料

难道6657不需要ddr configuration table 6678需要ddr configuration table？？？

文档没有有关说明：

/*******************************************************************************

UINT32 configSelect_lsw; /* Bit map defining which registers to set */

UINT32 pllPrediv; /* Values of all 0s will disable the pll */
UINT32 pllMult;
UINT32 pllPostDiv;
