[Buildroot] freescale_imx31_3stack_defconfig fails to build

[Thomas Petazzoni]

Vincent, Gary, Fabio,

I'm contacting you because the freescale_imx31_3stack_defconfig
doesn't build anymore, with the following error during the kernel
build:


arch/arm/mach-imx/built-in.o: In function `init_mmdc_lpddr2_settings':

See:

Is one of you interested in maintaining/fixing this board ? If so,
could you fix it and also submit a patch to add yourself to the
DEVELOPERS file ?

Thanks!

I can send a patch converting the defconfig to use a mainline kernel instead.

Would be good, thanks! Do you have a way of testing it, or you don't
have access to the HW platform ?

If nobody has access to the HW platform, I think we could just as well
drop the defconfig.

Best regards,

Yes, we have a mx31pdk board in the office.

I will try to have access to it this week and give it a try with mainline.

The mx31pdk board I have access to is bricked and it will take me some
time to unbrick it.

If anyone else has access to this board and would like to maintain it
in Buildroot with a mainline kernel, then I am OK to drop the
defconfig.

Thanks

Ops, I meant "If anyone else does not have access to this board..."

Fabio, Vincent,

The freescale_imx31_3stack_defconfig in Buildroot no longer builds,
because the Linux kernel version used in this defconfig is too old, and
doesn't build with gcc 5.x.

Has one of you access to this platform, and be willing to update this
defconfig?

See
http://free-electrons.com/~thomas/pub/buildroot-defconfigs/freescale_imx31_3stack_defconfig.log.FAIL
for the full build log.

Thanks!

Thomas

I think we should be able to use the latest mainline on mx31pdk.

I will try to get access to a mx31pdk and will give it a try with
latest mainline.

Thanks

Great, thanks!

Bonus point for other improvements to the defconfig, such as adding the
build for the bootloader, etc :)

Thanks,

Yes, I thought about that as well. Mainline U-Boot should also boot
fine on this board, so hopefully I will be able to test it next week.

Thanks

If this platform is difficult to get access to, and rarely used, then
maybe we should just remove the defconfig in Buildroot? It doesn't make
a lot of sense to have defconfig for platforms that are not in use.

Yes, even for me it will be difficult to get access to a mx31pdk
board, so I am OK with removing its defconfig from Buildroot.
