[Buildroot] [PATCH v3 0/7] Add Microblaze internal toolchain

[Buildroot] [PATCH v3 0/7] Add Microblaze internal toolchain

[Spenser Gilliland]

This patch series adds a Microblaze internal toolchain from the sources at
http://github.com/Xilinx .

This series requires that the arc toolchain patches and github helper
patches are applied.

v2->v3:
  - Incorporated all review suggestions.
  - Rebased on arc v2 patches and github helper.

Spenser Gilliland (7):
  binutils: add microblaze internal toolchain
  gcc: add microblaze internal toolchain
  glibc: add microblaze internal toolchain
  gdb: add microblaze internal toolchain
  toolchain: enable microblaze toolchain
  toolchain: uclibc does not support microblze
  defconfigs: update microblaze defconfigs to use new toolchain

Hum, I see a libc/sysdeps/linux/microblaze in my uClibc tree. And also,
since there are some no-MMU variant of Microblaze processors, which C
library other than uClibc could they use?

That being said, I don't *require* you to add the support for uClibc.
Having glibc/eglibc support is already good. We can add uClibc support
later on.

Best regards,

Thomas

In the distant past there may have been a version of uclibc that worked
with microblaze.  However from my limited testing, the current toolchain
does not work with uclibc.

Sounds great.

Ok. But then which C library are Microblaze non-MMU users using?

Likely a version from petalinux.  This needs to be investigated further to
see if uclibc support is possible with newer toolchains and any patches
from petalinux.

Tried it here, and everything builds fine. I even enabled a couple of random packages, and no problems seen. Note that I don't have a platform to actually run the binaries on, so this is a build-only test.
