Subject: [PATCH] arm: compressed: add appended DTB section
|
|
|
|
This adds a appended_dtb section to the ARM decompressor
|
|
linker script.
|
|
|
|
This allows using the existing ARM zImage appended DTB support for
|
|
appending a DTB to the raw ELF kernel.
|
|
|
|
Its size is set to 1MB max to match the zImage appended DTB size limit.
|
|
|
|
To use it to pass the DTB to the kernel, objcopy is used:
|
|
|
|
objcopy --set-section-flags=.appended_dtb=alloc,contents \
|
|
--update-section=.appended_dtb=<target>.dtb vmlinux
|
|
|
|
This is based off the following patch:
