Second thought.
With generic mmc framework, we can instance multiple mmc devices. Then
we can probe one of them when we want.
#ifdef CONFIG_GENERIC_MMC
int board_mmc_init(bd_t *bis)
{
int rc = 0;
#ifdef CONFIG_MMC_SPI
extern int mmc_spi_init(uint bus, uint cs, uint speed, uint mode);
mmc_spi_init(CONFIG_MMC_SPI_BUS,
CONFIG_MMC_SPI_CS_0,
CONFIG_MMC_SPI_SPEED,
CONFIG_MMC_SPI_MODE);
mmc_spi_init(CONFIG_MMC_SPI_BUS,
CONFIG_MMC_SPI_CS_1,
CONFIG_MMC_SPI_SPEED,
CONFIG_MMC_SPI_MODE);
#endif
return rc;
}
#endif
