Subject: [PATCH] MIPS: zboot: put appended dtb into a section
|
||
|
|
|
||
|
|
This will make a separated section for dtb appear in ELF, and we can
|
||
|
|
then use objcopy to patch a dtb into vmlinuz when RAW_APPENDED_DTB
|
||
|
|
is set in kernel config.
|
||
|
|
|
||
|
|
command to patch a dtb:
|
||
|
|
objcopy --set-section-flags=.appended_dtb=alloc,contents \
|
||
|
|
--update-section=.appended_dtb=<target>.dtb vmlinuz vmlinuz-dtb
|
||
