QorIQ U-Boot binary for SD card booting compiled during build process (either u-boot.bin or u-boot-with-spl.bin) cannot be directly loaded by QorIQ pre-PBL BootROM. Compiled U-Boot binary first needs to be processed by Freescale boot_format tool as described in doc/README.mpc85xx-sd-spi-boot 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 code. Boot sector needs to be at the beginning of the image, so when compiling only proper U-Boot without SPL then it needs to be in proper U-Boot. When compiling SPL with proper U-Boot then it needs to be only in SPL. Support can be enabled by a new config option FSL_PREPBL_ESDHC_BOOT_SECTOR. 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 image could be stored on the SD card.
