[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,

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.

Tested-by: Mischa Jonker <mjonker@synopsys.com>

Thanks,

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?

Thanks!

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.
