Changes v6 -> v8 (Liviu Dudau):
- Add support for Juno r0
- Documentation updated with boot parameter configuration
- Created a buildroot defconfig for each Juno model
Changes v6 -> v7 (Arnout Vandecappelle):
- Commit id was updated
- Custom image name was removed from buildroot' defconfig
Changes v5 -> v6 (Arnout Vandecappelle):
- replace Juno r1 for Juno (applicable to r0 and r1)
- some configs were removed from defconfig
Changes v4 -> v5:
-Added changelog to the patch
Changes v3 -> v4(Thomas Petazzoni):
-The kernel' arm64 defconfig lacks a considerable amount of configuration items regarding the Juno board, and that is the reason of this custom kernel configuration file.
-The ARM Juno needs a kernel image called Image, and that it the reason why BR2_LINUX_KERNEL_IMAGE_TARGET_CUSTOM is being used. -A new readme.txt was produced.

I am not sure why your v9 does not appear in patchwork, but v8 does. Anyway, this is still not good, because the kernel commit your defconfig uses no longer exists in the Linaro Git repository, so the download fails:

linux 0d752ce2de3057e12e220d104beb02744147be4f Downloading

Doing full clone
Cloning into bare repository 'linux-0d752ce2de3057e12e220d104beb02744147be4f'...
fatal: not a tree object

It works for you because you have the tarball'ed kernel in your $(BR2_DL_DIR), but it won't work for anyone else.

You should make sure to use a commit in a branch that the Linaro developers will not rebase, otherwise the commit will disappear in the future.

Also, another problem of your submission is that you're adding two defconfigs, while there's no reason to do so. The only difference between the two is the Device Tree to be built. And we can perfectly build two Device Trees in a single defconfig.

So could you apply the attached patch on top of yours (which addresses this problem), and squash it with your commit ?

Thanks!

Thomas

PATCH v9 1/1 board: add support for ARM Juno r0 and r1 Development Boards

Hi Thomas,

I will check it and send a v10 today. Thanks for the buildroot' defconfig tip.
