[Buildroot] [PATCH 0/8] configs: defconfigs for Atmel boards

[Alexandre Belloni]

Hi,

This series updates and adds defconfigs for the recent(ish) atmel boards. They
use Atmel's u-boot and kernel tree and are meant to be flashed on the NAND
flash.

Alexandre Belloni (8):
  configs: update at91sam9g45m10ek defconfig
  configs: add defconfig for Atmel at91sam9rlek
  configs: add defconfig for Atmel at91sam9x5ek
  configs: add defconfig for Atmel sama5d3xek
  configs: add defconfig for Atmel sama5d4ek
  configs: add defconfig for Atmel sama4d4 Xplained Ultra
  configs: add defconfig for Atmel sama5d3 Xplained
  configs: rename atmel_xplained_defconfig

[Buildroot] [PATCH 8/8] configs: rename atmel_xplained_defconfig

[Alexandre Belloni]

For consistency, rename atmel_xplained_defconfig to
atmel_sama5d3_xplained_mmc_defconfig as this configuration supports
booting the sama5d3 Xplained with an MMC card (as opposed to the NAND
flash).

Since you are moving all of the Atmel boards to use NAND boot
configuration, it would be good to have a 'README' that explains how
to load the boards utilizing the SAM-BA tool (it appears all the NAND
configurations are using this). At minimum it would be to point to
Linux4SAM wiki for loading instructions.

Thoughts?

Thanks,
-Ryan

I believe the readme.txt under board/atmel/xplained should be updated
to say atmel_sama5d3_xplained_mmc_defconfig instead of
atmel_xplained_defconfig.

Thanks

Sure, I'm actually planning to provide the tcl scripts to use with
SAM-BA to help people load the generated images on their board.

Indeed, I'll update it.

'linux-3.18-at91' appears to be a branch which means that it could be
updated and break this config?

I believe in order to ensure that a build is reproducible for everyone
that this should be a tag or commit SHA. This would also apply to all
your other new NAND configurations for the Atmel boards.

Thanks,

That is the expected behaviour. This branch must not break. I'm not
saying it won't break but if it ever breaks, it will definitively be
fixed.

OK - that is fine as I don't really have a strong opinion on this so
leaving it as the branch is fine with me. I was more so making the
observation.

Dear Alexandre Belloni,

No, please don't use a branch. Never ever. This makes the build
non-reproducible. And also means that once a
linux-linux-3.18-at91.tar.gz tarball has been created in $(DL_DIR), it
is never redownloaded even if the branch is updated.

So please do like Ryan said: use a tag or a commit ID. Feel free to
update this commit ID or tag as often as you want by sending patches,
but don't use a branch name.

Thanks,

Thomas

[Buildroot] [PATCH 0/8] configs: defconfigs for Atmel boards

Fully agreed.

Alexandre, please also include generating a NAND capable filesystem
image as part of those defconfig, so that they can easily be
flashed/used on the boards. I guess UBI images is going to be the most
appropriate solution. But clearly, such defconfigs should not generate
just a tarball.

Thanks

Typo in the commit title: sama4d4 -> sama5d4.

 Actually, I think it's better to use SD card images where possible.

- If you're using it just for experimentation, then the SD card is a much more
flexible and less risky way to experiment. Personally, I even prefer
kernel-linked-with-initramfs (and DTB) images, since that's just a single file
and it automatically gives you the rest of the SD card as a FAT partition.

- If you want to use it for an actual product (prototype), then you're anyway
going to have to study in a bit more detail how the flash works and you'll
probably want to do a slightly more complicated flash partitioning.


 That said, I do think it's really useful to have those tcl scripts for using
SAM-BA.


 And of course, since I never use the defconfigs myself, my opinion is probably
not that important.


 Regards,
 Arnout
