Re: [RFC V2] EDK2 Platform Proposal

Hi Sakar,

Apologies for lag.
What follows are my thoughts, not really discussed with Andrew/Mike.

No, this was one of the original ideas, but we decided on using a
completely separate structure and utilise PACKAGES_PATH to link the
repositories together for building.

On the one hand, I see no reason to change the minnowboard UDK branch,
the one branch that will have a strict layout is
edk2-platforms/master. Others will probably align to a similar layout
for expedience, as time progresses.

That would be my view, yes. Clearly this would simplify migrating new
platforms to edk2/master when desired..

I originally envisioned something more like OpenPlatformPkg (well, I
would, wouldn't I). But one of the things we clarified during
discussions at the recent plugfest was that device drivers, for
devices usable across multiple platforms, belong in edk2/master. So
once NewDirStruct happens, I'm likely to start migrating the
standalone drivers from OpenPlatformPkg into there.

Leif
