[roll] Roll fuchsia [kernel][phys] Ensure the correct allocations will survive into hand-off There are two cases around BootZbi::Load() in which we were ending up with duplicate allocations with type kKernel and kDataZbi: (1) In physboot, we Load() a kernel ZBI alone, yielding a spurious data ZBI allocation from its empty tail, which we then overwrite. (2) TrampolineBoot allocates staging kernel and data ZBI images for the purposes of trampolining, but these clash with the fixed-address versions we reserve ahead of time. We expediently address both of these situations with simple freeing or recharacterization of types post-Load(). This is easy enough to do, readable, and in (1) involves codepaths that are not long for this world. As logging feedback that the correct kKernel and kDataZbi allocations do end up surviving, we add these types to those included in the desired set of hand-off allocations.

This repository contains Fuchsia's Global Integration manifest files.
All changes should be made to the internal version of this repository. Our infrastructure automatically updates this version when the internal one changes.
Currently all changes must be made by a Google employee. Non-Google employees wishing to make a change can ask for assistance via the IRC channel #fuchsia on Freenode.
First install Jiri.
Next run:
$ jiri init $ jiri import minimal https://fuchsia.googlesource.com/integration $ jiri update
Third party projects should have their own subdirectory in ./third_party.
