From mboxrd@z Thu Jan 1 00:00:00 1970 From: Dick Olsson Date: Fri, 18 Dec 2020 20:27:57 +0000 Subject: [Buildroot] [PATCH v3 09/11] configs/qemu_aarch64_virt_efi_defconfig: new config for QEMU Virt EFI In-Reply-To: <20201218202646.1060123-1-hi@senzilla.io> References: <20201218202646.1060123-1-hi@senzilla.io> Message-ID: <20201218202646.1060123-10-hi@senzilla.io> List-Id: MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit To: buildroot@busybox.net This introduces a configuration for QEMU Virt that boots Linux with ATF and the EDK2 EFI firmware without any additional bootloaders. ATF is loading EDK2 in EL2 using the BL33 payload configuration.
