Tom Warren23d7fe92012-12-11 13:34:18 +000030 * kernel_addr_r must be within the first 128M of RAM in order for the
31 * kernel's CONFIG_AUTO_ZRELADDR option to work. Since the kernel will
32 * decompress itself to 0x8000 after the start of RAM, kernel_addr_r
33 * should not overlap that area, or the kernel will have to copy itself
34 * somewhere else before decompression. Similarly, the address of any other
35 * data passed to the kernel shouldn't overlap the start of RAM. Pushing
Jonathan Hunter80239362019-02-12 16:03:14 +000036 * this up to 32M allows for a sizable kernel to be decompressed below the
Tom Warren23d7fe92012-12-11 13:34:18 +000037 * compressed load address.
38 *
Jonathan Hunter80239362019-02-12 16:03:14 +000039 * fdt_addr_r simply shouldn't overlap anything else. Choosing 48M allows for
40 * the compressed kernel to be up to 32M too.

Jonathan Hunter80239362019-02-12 16:03:14 +000042 * ramdisk_addr_r simply shouldn't overlap anything else. Choosing 49M allows
Tom Warren23d7fe92012-12-11 13:34:18 +000043 * for the FDT/DTB to be up to 1M, which is hopefully plenty.
