+ * kernel_addr_r must be within the first 128M of RAM in order for the

+ * should not overlap that area, or the kernel will have to copy itself
+ * somewhere else before decompression. Similarly, the address of any other
+ * data passed to the kernel shouldn't overlap the start of RAM. Pushing
+ * this up to 16M allows for a sizable kernel to be decompressed below the
+ * compressed load address.

+ * fdt_addr_r simply shouldn't overlap anything else. Choosing 32M allows for

+ * ramdisk_addr_r simply shouldn't overlap anything else. Choosing 33M allows
