+All Rockchip platforms, (except rk3128 which doesn't use SPL) generate a

 To write an image that boots from a SD card (assumed to be /dev/sda):

 ^^^
 
-The SPI boot method requires the generation of idbloader.img with help of the mkimage tool.
+Some platforms also generate a SPI flash full boot image, controlled by the
+CONFIG_ROCKCHIP_SPI_IMAGE configuration option.
 
-SPL-alone SPI boot image:
+This image can be copied onto an SD card and written to SPI flash. Note that
+the offset at which the image should be written to is different between SoCs.
