Upstream linux DT naming doesn't align with the U-Boot DT, which may not always be the case so this allows using BOOTENV_EFI_SET_FDTFILE_FALLBACK where it might be appropriate for some boards. Signed-off-by: Peter Robinson <pbrobinson@gmail.com> Signed-off-by: Tom Warren <twarren@nvidia.com>

* Memory layout for where various images get loaded by boot scripts:
|
|

|
|
* scriptaddr can be pretty much anywhere that doesn't conflict with something
|

|

|
|
* kernel_addr_r must be within the first 128M of RAM in order for the
|
|
* kernel's CONFIG_AUTO_ZRELADDR option to work. Since the kernel will
|
|
* 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.
