Subject: [PATCH 4/7] ipq806x: import bootargs-append from IPQ40xx
|
|
|
|
This imports the patch that adds bootargs-append support from IPQ40xx.
|
|
|
|
This way we can append additional boot arguments from DTS instead of only being able to overwrite them.
|
|
|
|
This way dual firmware devices can use the rootfs number that bootloader passes to decide from what to boot.
|
|
But we still need to append console info and ubi root info.
|
|
|
|
This is used by Edgecore ECW5410.
