>BootROM requires that image on SD card must contain special boot sector.
>Implement support for generating this special boot sector directly in U-Boot start

>Support can be enabled by a new config option

>Via other two additional options FSL_PREPBL_ESDHC_BOOT_SECTOR_START and
>FSL_PREPBL_ESDHC_BOOT_SECTOR_DATA it is possible to tune how final U-Boot
