Tom Warrenf01b6312012-12-11 13:34:18 +000034 * kernel_addr_r must be within the first 128M of RAM in order for the
35 * kernel's CONFIG_AUTO_ZRELADDR option to work. Since the kernel will
36 * decompress itself to 0x8000 after the start of RAM, kernel_addr_r
37 * should not overlap that area, or the kernel will have to copy itself
38 * somewhere else before decompression. Similarly, the address of any other
39 * data passed to the kernel shouldn't overlap the start of RAM. Pushing
Jonathan Hunterf16e3112019-02-12 16:03:14 +000040 * this up to 32M allows for a sizable kernel to be decompressed below the
Tom Warrenf01b6312012-12-11 13:34:18 +000041 * compressed load address.
42 *
Jonathan Hunterf16e3112019-02-12 16:03:14 +000043 * fdt_addr_r simply shouldn't overlap anything else. Choosing 48M allows for
44 * the compressed kernel to be up to 32M too.

Jonathan Hunterf16e3112019-02-12 16:03:14 +000046 * ramdisk_addr_r simply shouldn't overlap anything else. Choosing 49M allows
Tom Warrenf01b6312012-12-11 13:34:18 +000047 * for the FDT/DTB to be up to 1M, which is hopefully plenty.
