This commit adds very basic support to build for the Nios II
architecture. Toolchain support is still missing and instead
we need to use an external custom toolchain.
Notice that this architecture had been previously removed in
Buildroot 2010.05-rc1 release (as explained in the CHANGES file)
and this commit adds it back.

Then you probably want to exclude it from the buildroot toolchain.

Why do you want to support two patchlevels of the same base version?

I want to support buildroot toolchain, but I'm not sure when I'll be able
to do that.

Yes, I was aware of that. I tried to find such information, but couldn't :-(
Any idea how do I get that information from the toolchain itself?

Not sure, actually. Just added all the options currently available.
Do you think is silly? Should I leave the latest one alone?

cross-gcc --version
cross-gdb --version
cross-ar --version
ls -l output/staging/lib*/libc-*.so
Kernel version is a bit more difficult: cat
output/staging/usr/include/linux/version.h and convert the decimal
version number to hex.
Look at the rest of the toolchain-external/Config.in for examples.
The supported architectures should also be mentioned, but that may be
more difficult.

Yes, only the latest one.
We do usually keep an older version around as well, but I'm not really
sure why. For the Sourcery toolchains it makes sense because they have
different gcc versions, but the Linaro toolchains often only have
bugfixes between one version and the next.

Arnout

Usually, all the Sourcery CodeBench toolchain have a document in
share/doc/<tuple>/pdf/getting-started.pdf with many details about the
toolchain.
Otherwise:
* nios-linux-gcc -v
* nios-linux-gdb -v
* find . -name 'ld-*.so' will identify which ld-2.xx.so, which will
tell you the version of glibc

Hum?
> Do you think is silly? Should I leave the latest one alone?
You can support multiple versions, but not multiple patchlevel of the
same version, because it's silly.
Since I know you know how kernel versions work, what you did is like
supporting 3.10.6 and 3.10.7: it's pointless, 3.10.7 is basically the
same as 3.10.6 with a few additional fixes. Of course, supporting both
3.9 and 3.10 might make sense.
Look at the other Sourcery Codebench toolchain entries in Buildroot. We
support multiple versions, but not multiple patchlevel of the same
version.
Thanks!
Thomas

See toolchain/Config.in. You can add a !BR2_nios2 in both
BR2_TOOLCHAIN_BUILDROOT and BR2_TOOLCHAIN_CTNG.

You can do that later. Just exclude the internal and crosstool-ng
backends for now.
Best regards,
Thomas

Ah, good hint. The PDFs have many details, indeed.

Yup, I manage to get up to here....

.. and I couldn't get to get the libc and binutils version.

Sure. Now I see why it was silly.

Mmm... what do you mean by supported architectures?
I'm not an expert Nios-II user (just started working on it) but there doesn't
seem to be any architectural variants.

Speaking of toolchains. Any recomendations on how to *choose* a toolchain?
Should I safely use Sourcery?
Should I prefer Buildroot internal (when we add support for it)?
Which should be the rationale behind such decision? (aside from the
fact the buildroot toolchain allows to be tuned)
Thanks a lot for the help!

External toolchain has the advantage that you don't have to spend time
(about an hour) on building it.
Internal toolchain has the advantage that it is configurable, and can
be uClibc based and therefore smaller. The difference between uClibc and
glibc is in the order of 1MB, so it only really makes sense when you want
a really small rootfs.

Arnout
