,but here only USDHC1 is initialized.
If only USDHC1 is initialized you can skip the for loop.
default:printf("Warning: you configured more USDHC controllers""(%d) than supported by the board\n", i + 1);return 0;}if (fsl_esdhc_initialize(bis, &usdhc_cfg[i]))printf("Warning: failed to initialize mmc dev %d\n", i);
If fsl_esdhc_initialize() fails you are returning 0, whic is wrong.
You want this probably:
ret = fsl_esdhc_initialize(bis, &usdhc_cfg[i]); if (ret) return ret;
Or if only USDHC1 is used you can do:
ret = fsl_esdhc_initialize(bis, &usdhc_cfg[0]); if (ret) return ret;
}return 0;+} +#endif

You should use imx_ddr_size() here.
