build: Rework patch mechanism for Fuel submodules
While refactoring the patching mechanism, take care of: - Sync submodule handling with Fuel@OPFNV; - build: Investigate/prepare for moving patches to Fuel@OPNFV; - build: Investigate divergent fuel-mirror; - ISO build: cacheid for Fuel comps should not depend on Armband git commit; CHANGE: Rename/shuffle patches while grouping them in "features", preparing for upstreaming them to Fuel@OPNFV and beyond. CHANGE: Allow linking patches for better representing the dependency between one patch and different features. e.g. 0001-Add-arch-to-nailgun-release-and-target-image.patch: - part of `multiarch-fuel`, because it extends Fuel; - part of `direct-kernel-boot`, as arch is required for that; - part of `cross-bootstrap`, target image is arch-dependent; NOTE: Patch links are not staged to Fuel@OPNFV, they only serve as markers that a specific patch is part of a feature. CHANGE: Kill all Fuel component submodules, now handled in Fuel@OPNFV: - fuel-agent - fuel-astute - fuel-library - fuel-mirror - fuel-nailgun-agent - fuel-web CHANGE: Move armband-fuel-config.mk to armband git root. FIXME: m1.micro-Increase-profile-RAM-size-to-128MB.patch is NOT part of `cross-bootstrap` feature, but patch context says so ... FIXME: 0001-Add-arm64-deb-repositories-setup.patch is broken at `make patches-export` by removing spaces at EOL. v2 -> v3: * Phony patch support (links to show a patch belongs to a feature); * Updated README.md v3 -> v7: * Re-export Fuel submodules & plugins patches (update patch context); * Update Cavium mail addresses (s/caviumnetworks.com/cavium.com/); * Ignore submodule changes; * Add armband git repo info to gitinfo_fuel.txt at build time; Implements: ARMBAND-136 Closes-bug: ARMBAND-95 Closes-bug: ARMBAND-93 Closes-bug: ARMBAND-92 Change-Id: I1a236d9f43b2e6dca22055911f696b43c22b5973 Signed-off-by: Alexandru Avadanii <Alexandru.Avadanii@enea.com>

+Subject: [PATCH] Use qemu-debootstrap for image creation
+
+This commit adds qemu-debootstrap support and a command line argument
+`target_arch` which can be used for choosing the architecture to build
+the image for. The architecture detection from environment settings is
+not yet implemented.

+
+arm64 udev in Ubuntu Trusty is broken, so we had to provide our own
+patched udev package in armband MOS repos.
+
+Due to dpkg version comparison algorithm, our MOS version of udev
+is considered a downgrade, which requires --force-yes for
+apt-get dist-upgrade to work and pick up this version, otherwise
+bootstrap/target image build would fail with apt-get error code 100.
+
+This change can be dropped later, if other packages do not manifest
+the same behavior.
