Both is possible. Older U-Boot versions only passed the bd_t struct to the 
kernel. For those U-Boot's the wrapper is needed. More recent U-Boot versions 
support passing a device-tree blob to the kernel. U-Boot patches the correct 
memory size in this blob.

As a matter of fact, I never used the wrapper before. U-Boot supports passing 
the device-tree blob to Linux since quite some time now.

Best regards,
Stefan
