[Buildroot] [PATCH 0/4] mender updates

[aduskett at gmail.com]

From: Adam Duskett <aduskett@gmail.com>

The upstream developers asked me to update the mender packages as a favor, as
they are pretty outdated right now.

This patch series includes updates to all of the mender packages and a small
change that removes auto-selecting uboot-tools if uboot is selected in
mender/Config.in (the patch itself has an explination as to why.)

Adam Duskett (4):
  package/mender-artifact: bump to version 3.4.1
  package/mender: bump version to 2.4.2
  package/mender-grubenv: bump version to
    f39c2c7ec7c9c24aae0108a9b04a0e6e61a3e96b
  package/mender: Do not automatically select uboot tools if uboot is
    selected

[Buildroot] [PATCH 3/4] package/mender-grubenv: bump version to f39c2c7ec7c9c24aae0108a9b04a0e6e61a3e96b

[aduskett at gmail.com]

From: Adam Duskett <aduskett@gmail.com>

According to the developers, mender-grubenv is no longer tagging releases for
the mender-grubenv project. However, they asked me if I could submit a patch
upstream to update the package to the latest commit, including quality of life
improvements since the last official 1.3.0 release.

Notable improvements are:
  - Support for separate A/B kernel partitions.
  - Use regexp to dynamically set mender_grub_storage_device
  - Add "rootwait" as a default rootfs argument

Other changes:
  - Update license hashes due to a copyright year bump.

[Buildroot] [PATCH 4/4] package/mender: Do not automatically select uboot tools if uboot is selected

[aduskett at gmail.com]

From: Adam Duskett <aduskett@gmail.com>

Because uboot requires a set of unique patches for each board, the upstream
package developers are phasing out supporting uboot wherever possible.
Instead, they recommend using Grub as a secondary bootloader and using
mender-grubenv whenever possible.

As such, remove selecting uboot tools when uboot is selected, and instead add
a note in the help section about what Mender requires for uboot and grub-based
systems.

It's a bit odd to drop these.

Indeed, here you are precisely saying that fw_printenv is needed. What
about keeping the selects *and* adding your Config.in comment, perhaps
without the "uboot-tools must be selected". It would be nice to have
some more specific reference to the Mender U-Boot patches.

What about selecting BR2_PACKAGE_MENDER_GRUBENV then when
BR2_TARGET_GRUB is enabled?

Thanks!

Not really, because mender-grubenv has it's own fake fw_printenv.

The problem with this suggestion is that mender-grubenv has its own
fw_printenv. So if both were built then
uboot's fw_printenv may be built last, which would overwrite the
fw_printenv provided by mender-grubenv.

I could provide a URL to the meta-mender repository for links to the
uboot patches. Would that work?

Ah, so the problem comes from the situation where both U-Boot and grub
are enabled, I see. I still find that a very odd combination, are there
really people who do that?

That being said, with that info, indeed you can't really know if
U-Boot's fw_printenv should be used, or mender-grubenv's fw_printenv
should be used, so not selecting any of them probably makes the most
sense.

That would certainly be a useful addition.

Thanks!

Yes actually! Mender recommends doing it this way because then a developer
only needs to use mender-grubenev instead of porting the uboot patches to every
new platform. Uboot is indeed capable of loading grub as a kernel image which is
quite nice!

I'm glad you agree!

Thanks, I've applied those patches to master!

I do have a few comments/questions on this one, so I'll reply to it
directly.
