[Buildroot] [PATCH 0/4] configs: atmel: update of old boards

[Ludovic Desroches]

Hi,

Thomas reported me that some components (kernel or u-Boot) are no longer
compiling due to incompatibilities with gcc.

Since there is no longer official releases (linux4sam) for these products,
they will rely on mainline versions for U-Boot and Linux. AT91bootstrap is
bumped to a recent version.

Regards

Why enable both U-Boot and Barebox?

For the sake of reproducibility you should set this to the version you tested, 
say, 4.8.6. The same goes for other patches in this series.

I'm not sure this is actually useful because the amount of testing is
minimal and it just increases the maintenance burden.

I don't understand. How would locking a specific kernel version in the 
defconfig increase maintenance burden? Any tested kernel version would do. We 
just want to ensure consistent user experience. Otherwise the built kernel 
will change with the default value of BR2_LINUX_KERNEL_VERSION.

Yeah, that's my point. Any kernel version will do and that avoids having
to update it in the defconfig all the time, hence less maintenance. The
previous defconfig has not been building for a while (basically, since
the switch to gcc5).

That's the goal. Kernel was no longer compiling because it was too old
to be used with gcc5. We may have the same situation in the future and
we'll simply choose the latest kernel release for the update as I do today.
That's why Alexandre says that it will increase the maintenance.

I don't know why Barebox was selected but the 'official' bootloader is
U-Boot for all our products that's why I add it. I kept Barebox because
it was already selected and I don't know if someone is still using it or
not.

As Alexandre said, we don't want to spend time for the maintainance of these
old boards so sticking to the mainline seems to be the way to go. Giving a
version is a kind of commitment but we no longer perform tests on these
boards excepting kernel boot with kernelci.

But the end result is a defconfig that doesn't make any sense.

Please provide a defconfig that makes sense, and with an updated
readme.txt if you decide to change the bootloader (and therefore the
flashing instructions).

That's not Buildroot policy. We want defconfigs with fixed kernel and
bootloader versions, so that we know they have been tested.

If you are not able/willing to test those defconfigs, then we could
just as well remove them. But I'm not going to merge a defconfig that
doesn't comply with our policy of having a fixed kernel and a fixed
bootloader version.

Can I use a fixed version of the compiler too? It seems it makes sense
because this defconfig was tested but is no more compiling.

This could be an option indeed (reverting to gcc 4.x instead of gcc
5.x). However, the fact that no-one is willing to test/maintain this
defconfig is a sign that nobody is interested in it. So I'd rather
remove it, than keep a defconfig that gets never updated, even when
there is a build issue.

So, options are clear:

 1. Remove the defconfig entirely.

 2. Update the defconfig in the proper way, minimally tested on HW.

Thomas
