+WARNING:
+--------
+This file should contain the bin_hdr generated by the original Marvell
+U-Boot implementation. As this is currently not included in this
+U-Boot version, we have added this placeholder, so that the U-Boot
+image can be generated without errors.
+
+If you have a known to be working bin_hdr for your board, then you
+just need to replace this text file here with the binary header
+and recompile U-Boot.

+Install U-Boot on eMMC:
+-----------------------
+
+The ROM loads the bootloader from eMMC first boot partition at offset 0. This
+is unlike load from SD card that is at offset 512. As a result, the offset of
+the main U-Boot image on the eMMC boot partition changes. Set
+CONFIG_SYS_MMCSD_RAW_MODE_U_BOOT_SECTOR to 0x140 for SPL to load U-Boot from
+the correct location.
+
+To make SPL load the main U-Boot image from the eMMC boot partition enable
+eMMC boot acknowledgement and boot partition with the following U-Boot
+command:
+
+  mmc partconf 0 1 1 0
+
+Install U-Boot on eMMC boot partition from Linux running on Clearfog:
+
+  echo 0 > /sys/block/mmcblk0boot0/force_ro
+  dd if=u-boot-spl.kwb of=/dev/mmcblk0boot0
+
+Note that the SD card is not accessible when the Clearfog SOM has eMMC.
+Consider initial boot from UART (see below).
