 Also included are Zynq SoC configuration fragments and a generalised

 Support for MicroBlaze and Zynq has been available in upstream and
 linux-yocto for a number of releases. This series does not require any
 patching of the kernel source to enable any functionality of the target
 BSPs and is purely kernel configuration.

 Additionally included in this series is a fragment for debug purposes
 that enables the kernels DEBUG_DYNAMIC feature.

I noticed a missing config for zynq related to tiny kernel type after
doing some more testing with the 4.12 updates. Due to how tiny.scc
includes standard.scc (which includes arm.scc), however it ignores the
.cfg files, which meant CONFIG_ARM_THUMB was not enabled for tiny
kernels. I've sent a patch to add this for the 4.9,4.10,master
branches.

Otherwise all looks good, and I have sent a patch for the 4.12 changes as well.

Thanks,

With the qemumicroblaze* targets in the future once all changes have
been applied to oe-core you should be able to test them with just qemu
if needed.

But I am good to keep a look out on changes to the linux-yocto kernel
and test/validate for these configs.

I had not yet tested these with 4.10 (which is reason why RFC), though
just tested against v4.10/-dev and all looks good.

However there are some minor changes that are needed for 4.12 as these
cfgs were targeting 4.11 and earlier. I will send a follow up patch
once sorted to handle the 4.12 differences.

These are really clean, and self documenting. I wouldn't have a problem
carrying these along with the main kernel-cache branches.

I don't have the h/w .. so obviously you'd control all the updates (and
any necessary fixes) that weren't clear to me (i.e. options that have
disappeared, or dependency issues, I can handle).

I had one question about the BE machine, but that is mostly for my
information only.

I'll queue these up for my 4.10 and master branch (which is now 4.12+
for linux-yocto-dev).
