* as that will normally be within the kernel lowmem and thus visible via
* bootm_size and we only run on platforms with 256MB or more of memory.
+ *
+ * As a temporary storage for DTBO blobs (which should be applied into DTB
+ * blob), we use the location 15.5 MB above the ramdisk. If someone wants to
+ * use ramdisk bigger than 15.5 MB, then DTBO can be loaded and applied to DTB
+ * blob before loading the ramdisk, as DTBO location is only used as a temporary
+ * storage, and can be re-used after 'fdt apply' command is done.
