[PATCH 0/5] Introduce powerpc64 LE architecture support

[Khem Raj]

This patchset adds base support for building ppc64 in Litte-Endian mode,
the linux-yocto changes and qemu related changes will make it buildable
target out of box, but that is not yet made available

The following changes since commit ecbf203e34484731dcb6acc5e75df79cb86e55dc:

  sstatesig: Improve debug output if getpwuid() fails (2020-01-16 22:33:09 +0000)

are available in the Git repository at:

  git://git.yoctoproject.org/poky-contrib kraj/ppc64le
  http://git.yoctoproject.org/cgit.cgi/poky-contrib/log/?h=kraj/ppc64le

Khem Raj (5):
  classes,conf,lib: Add support for powerpc64le
  gcc: Enable 32bit powerpcle at multi-arch for powerpc64le
  openssl: Add powerpc64 LE support

[PATCH 1/5] classes, conf, lib: Add support for powerpc64le

[Khem Raj]

LE is default for modern powerpc64, power8+

PowerPC64 Little Endian Linux ABI specifies Power8 as the minimum ISA.
The basic ABI can run on earlier versions of the 64 bit PowerPC ISA,
but it was helpful to define a new, minimum instruction set for Linux
distribution releases during the switch to Little Endian.

[PATCH 2/5] gcc: Enable 32bit powerpcle at multi-arch for powerpc64le

[Khem Raj]

Even though we do not expect any legacy ( 32bit ) for LE, linux-yocto
does enable the compat code, so enable 32bit support to get that going
