Stephen Warren131a1e62013-01-29 16:37:42 +0000157 * kernel_addr_r must be within the first 128M of RAM in order for the
158 * kernel's CONFIG_AUTO_ZRELADDR option to work. Since the kernel will
159 * decompress itself to 0x8000 after the start of RAM, kernel_addr_r
160 * should not overlap that area, or the kernel will have to copy itself
161 * somewhere else before decompression. Similarly, the address of any other
162 * data passed to the kernel shouldn't overlap the start of RAM. Pushing
163 * this up to 16M allows for a sizable kernel to be decompressed below the
164 * compressed load address.
165 *
166 * fdt_addr_r simply shouldn't overlap anything else. Choosing 32M allows for
167 * the compressed kernel to be up to 16M too.
168 *
169 * ramdisk_addr_r simply shouldn't overlap anything else. Choosing 33M allows
170 * for the FDT/DTB to be up to 1M, which is hopefully plenty.
