[Xen-devel] [PATCH STABLE] tools/firmware: update OVMF Makefile, when necessary

[Ian Jackson <ian.jackson@xxxxxxxxxx>]

On advice from Wei, I am about to push this squashed backport to the
stable trees.  We think this will help fix osstest on those branches
following the upgrade to Debian stretch.

Ian.

Subject: [PATCH] tools/firmware: update OVMF Makefile, when necessary

[ This is two commits from master aka staging-4.12: ]

OVMF has become dependent on OpenSSL, which is included as a
submodule.  Initialise submodules before building.

tools: only call git when necessary in OVMF Makefile

Users may choose to export a snapshot of OVMF and build it
with xen.git supplied ovmf-makefile. In that case we don't
need to call `git submodule`.

Fixes b16281870e.
