mion dunfell-2020.10 "Achill"

All,

This is the dunfell-2020.10 "Achill" release of the Network Grade Linux Project, mion.

Features:

• Initial Release!
• ONIE images built with Yocto Project
• Direct to disk images both with and without containers.
• Mender root filesystem update support
• Switched to Yocto multiconfig - parallel building of host and containers
• Removed Application and System Profiles in favour of standard images
• BSP supporting APS Networks bf2556x-1t switch
• Defined BSP format for future switches
• ONLPv1 support
• Initial work on ONLPv2 recipe
• Container prebuilt feed
• Container CAPS working for ONLP*
• Removed all oryx code except for orxycmd which is now named “srunc”
• Extensive documentation at docs.mion.io
• mc_build.sh script for multiconfig builds (replaces scripts/build.py)
• Extensive code cleanup and refactoring
• Working KCONFIG for the APS Networks 25G switch

Known Issues:

• ONIE images are incompatible with containers/meta-mender but we do allow it to be built. We should probably bb.warn or bb.error when this happens.
• meta-mender needs to be disabled for ONIE images. If you require an ONIE image, you MUST remove the meta-mender layer or else things break.
• ONLPv2's onlpdump.py seems to be broken with the APS Networks 25G switch.
• Barefoot SDE is not on image. We know how this needs to happen, but we're bumping this to 1.1 as the SDE has a lot of specific requirements.
• We should introduce dynamic layers in bblayers for meta-mion- layers.
• QA automated testing is pretty minimal atm. ONLP has no test suite that we know of so this poses a bit of an issue.

Many thanks goes to the folks at APS Networks and Togán Labs for their
work on this exciting release.
