commit: https://git.buildroot.net/buildroot/commit/?id=793ee1011e84bd79fa3d146dbe6c14c7fba39648
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/master
The support for this architecture has been removed from the upstream
Linux kernel, as of commit:
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=aec499c75cf8e0b599be4d559e6922b613085f8f
Which states:
The nds32 architecture, also known as AndeStar V3, is a custom
32-bit RISC target designed by Andes Technologies. Support was added
to the kernel in 2016 as the replacement RISC-V based V5 processors
were already announced, and maintained by (current or former) Andes
employees.
As explained by Alan Kao, new customers are now all using RISC-V,
and all known nds32 users are already on longterm stable kernels
provided by Andes, with no development work going into mainline
support any more.
There has also been little to no maintenance done in Buildroot for
this architecture in recent times, so let's follow the Linux kernel
community decision and drop support for this CPU architecture.
