[Buildroot] [PATCH] raspberrypi2: kernel version does no more exist

[Jérôme Pouiller]

It looks like version 2c4959b of Raspberry kernel does no more exist:

$ git clone https://github.com/raspberrypi/linux.git
[...]
$ cd linux
$ git co 23c76b7f608e51258c6fca02aebeb5d588583149
fatal: reference is not a tree: 23c76b7f608e51258c6fca02aebeb5d588583149

Replace it by lastest version of 3.19 branch

I mean 'version 23c76b7' does no more exist.

Yeah, the RPi people are annoying, they constantly rebase their
branches so there's no way to have a stable commit. Yann posted an
issue to their github: https://github.com/raspberrypi/linux/issues/915.
Maybe we need to look into what they propose, apparently they have some
stable branches.

I've nonetheless applied your commit, after tweaking the commit log.

(Hint: "does no more exist" isn't proper English as far as I know, you
should say "does not exist anymore" I believe. Though I'm not a native
English speaker, so I might be wrong.)

 In that issue, popcornmix writes:

> The stable branches (e.g. 3.18.y) don't get rebased, so should have a linear history

so perhaps we should stick to the stable 3.18 branch instead? The
raspberry_dt_defconfig is based off the 3.18 branch, so why not do the same for
the RPi2?

 Arnout

Absolutely. I'm hoping to see some patches about this from our RPi
contributors. Yann? :-)

I recently tried a Raspberry Pi 2 with the 3.19 kernel from
raspberrypi2_defconfig, and it had issues mounting an ext2 rootfs
(presumably due to not finding mmcblk0p2, but I didn't debug). I
switched to a 3.18 kernel, and everything worked fine.

I don't mind sending a patch to switch to the 3.18 branch, but before
I did so, was there anything I missed on this issue? It looks like
it's been a couple of weeks since this email, and I didn't see other
RPi commits.

Thanks,
Frank
