Subject: [PATCH] arc add OWRTDTB section
|
|
|
|
This change allows OpenWRT to patch resulting kernel binary with
|
|
external .dtb.
|
|
|
|
That allows us to re-use exactky the same vmlinux on different boards
|
|
given its ARC core configurations match (at least cache line sizes etc).
|
|
|
|
""patch-dtb" searches for ASCII "OWRTDTB:" strign and copies external
|
|
.dtb right after it, keeping the string in place.
