|
||
|
|
* decompress itself to 0x8000 after the start of RAM, kernel_addr_r
|

* 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
|
||
|
|
* the compressed kernel to be up to 16M too.
|
||
|
|
*
|
||
|
|
* ramdisk_addr_r simply shouldn't overlap anything else. Choosing 33M allows
|
||
|
|
* for the FDT/DTB to be up to 1M, which is hopefully plenty.
