TI中文支持网各位TI的工程师大家好，我们这边项目需要AM335X的控制系统支持wifi功能，所以我选择了一个高通的方案qca9377，该模块接口是SDIO接口。我用的是EMMC2，驱动移植遇到了一个问题，驱动移植手册里的方法是，在linux-3.14.26-g2489c02\drivers\mmc\host\sdhci-esdhc-imx.c,在sdhci-esdhc-imx.c文件里添加WIFI扫描函数，但是我发现内核中并没有编译该文件，在Makefile中发现该文件的编译依赖于obj-$(CONFIG_MMC_SDHCI_ESDHC_IMX) += sdhci-esdhc-imx.o这个选项，内核中没有发现该选项，请问有没有遇到过类似的情况的，是否该编译选项依赖于其他的选项呢？
