Actually, check how it's distributed:

$ git grep mxsmmc_initialize board | sed "s at .*/@@"
apx4devkit.c:   return mxsmmc_initialize(bis, 0, NULL, NULL);
m28evk.c:       return mxsmmc_initialize(bis, 0, m28_mmc_wp, NULL);
mx28evk.c:      return mxsmmc_initialize(bis, 0, mx28evk_mmc_wp, NULL);
mx23_olinuxino.c:       return mxsmmc_initialize(bis, 0, NULL, mx23_olx_mmc_cd);
sc_sps_1.c:     return mxsmmc_initialize(bis, 0, NULL, NULL);

We have quite a bit of variance there. I wonder if using cpu_mmc_init() is worth 
it.
