[v10,0/5] aarch64 -> aarch32 cross compilation support

  Add support for aarch32 cross build in meson
and add aarch64 -> aarch32 cross build to Travis.

Aarch32 is an execution state that allows execution of 32-bit code on
armv8 machines. This execution state contains a superset of previous
armv7 32-bit instructions and features. Thus the aarch32 build is
distinct from arvm7 build.

v4:
Removed disabled drivers which actually build on arm32.
Also tested the patchset with series 9609 which fixes underlying
failures.

v5:
Changed the condition for running test-null.sh in ci.
Re-uploaded after underlying fixes have been committed.

v6:
Changed the condition for running test-null.sh again.
Reworked the patch to do aarch32 build instead of arvm7-a build.
Simplified meson build flags. Changed commit msgs.
Added 32b qualifier to .travis.yml.
Added a patch with fixes for bnxt.
Added a patch with cross compilation docs.

v7:
Rebased the patchset.

v8:
Removed Makefile additions from net/bnxt patch.

v9:
Changed ci test-null.sh condition, only run it if not
cross-compiling aarch64 nor aarch32.
Cleaned up docs.

v10:
Fixed doc: add aarch32 build guidance commit message.

Hi Folks,

This patch series has been submitted more than a month ago. There have been no comments. Should I just wait a bit more or what should I do?

Thanks,
Juraj

First thing to do is to get acks from Arm maintainers.
There are other patchset in the same area that I'm not sure they are ready.
It seems Arm team is a bit behind recently.

I previously thought I sent an ACK for this series.
