+Bootloader storage options
+==========================
+
+There are a few different storage options for the bootloader.
+This document explores two of these: eMMC and removable SD/MMC.

 Flash the image to eMMC
 =======================

+Create a bootable SD/MMC
+========================
+
+The idbspl.img contains the first stage, and the u-boot.img the second stage.
+As explained in the Rockchip partition table reference [2], the first stage
+(aka loader1) start sector is 64, and the second stage start sector is 16384.
+
+Each sector is 512 bytes, which means the first stage offset is 32 KiB,
+and the second stage offset is 8 MiB.
+
+Note: the second stage location is actually not as per the spec,
+but defined by the SPL. Mainline SPL defines an 8 MiB offset for the second
+stage.
+
+Assuming the SD card is exposed by device /dev/mmcblk0, the commands
+to write the two stages are:
+
+  > dd if=idbspl.img of=/dev/mmcblk0 bs=1k seek=32
+  > dd if=u-boot.itb of=/dev/mmcblk0 bs=1k seek=8192
+
+Setting up the kernel and rootfs is beyond the scope of this document.

+And that is it
