Subject: [PATCH 2/2] MIPS: lantiq: make it possible to build in no device tree
|
|
|
|
|
|
|
|
|
|
Now it is possible to build in no device tree at all and depend on the
|
|
|
|
|
boot loader providing one or someone concatenating a device tree to the
|
|
|
|
|
end of the image.

+ Legacy bootloaders do not pass a DTB pointer to the kernel, so
|
|
|
|
|
+ if a "wrapper" is not being used, the kernel will need to include
|
|
|
|
|
+ a device tree that matches the target board.

|
|

|
|
+ The builtin DTB will only be used if the firmware does not supply
|
|
|
|
|
+ a valid DTB.
