Tom Warren07067142013-01-28 13:32:13 +0000[diff] [blame]33 * kernel_addr_r must be within the first 128M of RAM in order for the
34 * kernel's CONFIG_AUTO_ZRELADDR option to work. Since the kernel will
35 * decompress itself to 0x8000 after the start of RAM, kernel_addr_r
36 * should not overlap that area, or the kernel will have to copy itself
37 * somewhere else before decompression. Similarly, the address of any other
38 * data passed to the kernel shouldn't overlap the start of RAM. Pushing
Jonathan Hunterf16e3112019-02-12 16:03:14 +0000[diff] [blame]39 * this up to 32M allows for a sizable kernel to be decompressed below the
Tom Warren07067142013-01-28 13:32:13 +0000[diff] [blame]40 * compressed load address.
41 *
Jonathan Hunterf16e3112019-02-12 16:03:14 +0000[diff] [blame]42 * fdt_addr_r simply shouldn't overlap anything else. Choosing 48M allows for
43 * the compressed kernel to be up to 32M too.

Jonathan Hunterf16e3112019-02-12 16:03:14 +0000[diff] [blame]45 * ramdisk_addr_r simply shouldn't overlap anything else. Choosing 49M allows
Tom Warren07067142013-01-28 13:32:13 +0000[diff] [blame]46 * for the FDT/DTB to be up to 1M, which is hopefully plenty.
