nios2: Add new architecture
PATCH 1/2 nios2: Add new architecture
From: Ezequiel Garcia <[email protected]>
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.

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.

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

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

* find . -name 'ld-*.so' will identify which ld-2.xx.so, which will tell you the version of glibc

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!

PATCH 1/2 nios2: Add new architecture

From: Ezequiel Garcia <[email protected]>
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.
Then you probably want to exclude it from the buildroot toolchain.
Ok, I'll take a look.
I want to support buildroot toolchain, but I'm not sure when I'll be able to do that.
Thanks,

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
