* 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
|
