Subject: [PATCH v3 edk2-platforms 2/2] Platform/ARM: import BootMonFs and ArmShellCmdRunAxf from EDK2
Date: Mon,  4 Dec 2017 22:12:35 +0000	[thread overview]
Message-ID: <20171204221235.11807-3-ard.biesheuvel@linaro.org> (raw)
In-Reply-To: <20171204221235.11807-1-ard.biesheuvel@linaro.org>

BootMonFs and ArmShellCmdRunAxf are only used on development boards
manufactured by ARM itself, so let's keep it under Platform/ARM where
it belongs.
