Subject: [PATCH edk2-platforms v2 05/13] Platform/ARM/Juno: import ArmJunoPkg from EDK2
Date: Thu, 16 Nov 2017 17:58:35 +0000	[thread overview]
Message-ID: <20171116175839.30012-6-ard.biesheuvel@linaro.org> (raw)
In-Reply-To: <20171116175839.30012-1-ard.biesheuvel@linaro.org>

Move ArmJunoPkg into edk2-platforms, so it can be removed from the main
EDK2 tree.

This allows use to remove the dodgy -I arguments to GCC to build shared
modules with a different copy of ArmPlatform.h, which was making it very
difficult to properly split the various modules into their own packages.
