* We setup defaults based on constraints from the Linux kernel, which should

* the kernel), FDT above 128MB (the maximum location for the end of the
* kernel), and the ramdisk 512KB above that (allowing for hopefully never
* seen large trees). We say all of this must be within the first 256MB
* 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.
