Hello,
The upstream Linux kernel community has removed the NDS32 architecture
support in commit
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=aec499c75cf8e0b599be4d559e6922b613085f8f.
There has been very little to no activity in Buildroot around this CPU
architecture recently, so let's drop the support for this CPU
architecture.
Thomas

As we're about to remove the nds32 architecture support, remove the
only defconfig that used this CPU architecture.

-Subject: [PATCH] scripts/dtc: Remove redundant YYLOC global declaration
-
-gcc 10 will default to -fno-common, which causes this error at link
-time:
-
- (.text+0x0): multiple definition of `yylloc'; dtc-lexer.lex.o (symbol from plugin):(.text+0x0): first defined here
-
-This is because both dtc-lexer as well as dtc-parser define the same
-global symbol yyloc. Before with -fcommon those were merged into one
-defintion. The proper solution would be to to mark this as "extern",
-however that leads to:
-
- dtc-lexer.l:26:16: error: redundant redeclaration of 'yylloc' [-Werror=redundant-decls]
- 26 | extern YYLTYPE yylloc;
- | ^~~~~~
-In file included from dtc-lexer.l:24:
-dtc-parser.tab.h:127:16: note: previous declaration of 'yylloc' was here
- 127 | extern YYLTYPE yylloc;
- | ^~~~~~
-cc1: all warnings being treated as errors
-
-which means the declaration is completely redundant and can just be
-dropped.

-=====
-
-Andestech(nds32) AE300 Platform
-
-The AE300 prototype demonstrates the AE300 example platform on the FPGA.
-It is composed of one Andestech(nds32) processor and AE300.
-
-How to build it
-===============
-
-Configure Buildroot
--------------------
-
-The andes_ae300_defconfig configuration is a sample configuration with
-all that is required to bring the FPGA Development Board:
-
- $ make andes_ae300_defconfig
-
-Build everything
-----------------
-Note: you will need to have access to the network, since Buildroot will
-download the packages' sources.
-
- $ make
-
-Result of the build
--------------------
-
-After building, you should obtain this tree:
-
-output/images/
- +-- vmlinux
- +-- rootfs.cpio
- +-- rootfs.tar
-
-How to run it
-=============
-
-Run
----
-
- Setup the Console with the rate 38400/8-N-1.
-
- $ cd output/images
- $ ../host/bin/nds32le-linux-gdb vmlinux
- $ target remote [your host]
- $ lo

Buildroot, drop the toolchain-external-andes-nds32 external toolchain
package.

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.
