+ * The 'boot' image needs to know the OBP path name of the root
+ * device. It also needs to know the initial block number of
+ * 'core' (which is 'diskboot' concatenated with 'kernel' and
+ * all the modules, this is created by grub-mkimage). This resulting
+ * 'boot' image is 512 bytes in size and is placed in the second block
+ * of a partition.
+ *
+ * The initial 'diskboot' block acts as a loader for the actual GRUB
+ * kernel. It contains the loading code and then a block list.
+ *
+ * The block list of 'core' starts at the end of the 'diskboot' image
+ * and works it's way backwards towards the end of the code of 'diskboot'.
+ *
+ * We patch up the images with the necessary values and write out the
+ * result.
