+Booting from an SD card on RK3188
+=================================
+
+For rk3188 boards the general storage onto the card stays the same as
+described above, but the image creation needs a bit more care.
+
+The bootrom of rk3188 expects to find a small 1kb loader which returns
+control to the bootrom, after which it will load the real loader, which
+can then be up to 29kb in size and does the regular ddr init.
+
+Additionally the rk3188 requires everything the bootrom loads to be
+rc4-encrypted. Except for the very first stage the bootrom always reads
+and decodes 2kb pages, so files should be sized accordingly.

+GPT partition layout
+----------------------------
+
+Rockchip use a unified GPT partition layout  in open source support.
+With this GPT partition layout, uboot can be compatilbe with other components,
