+The rockchip bootrom can load and boot an initial spl, then continue to
+load a second-level bootloader(ie. U-BOOT) as soon as it returns to bootrom.
+Therefore RK3288 has another loading sequence like RK3036. The option of
+U-Boot is controlled with this setting in U-Boot:
+
+	#define CONFIG_SPL_ROCKCHIP_BACK_TO_BROM

+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.
+
+# copy tpl, pad to 1020 bytes and append spl
+cat tpl/u-boot-tpl.bin > tplspl.bin
+truncate -s 1020 tplspl.bin
+cat spl/u-boot-spl.bin >> tplspl.bin
+tools/mkimage -n rk3188 -T rksd -d tplspl.bin out
+
+# truncate, encode and append u-boot.bin

+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,
+like miniloader, trusted-os, arm-trust-firmware.
