Subject: [Buildroot] [PATCH v3 05/11] configs/aarch64_efi_defconfig: build the EDK2 firmware from source
Date: Fri, 18 Dec 2020 20:27:33 +0000	[thread overview]
Message-ID: <20201218202646.1060123-6-hi@senzilla.io> (raw)
In-Reply-To: <20201218202646.1060123-1-hi@senzilla.io>

Prior to this, you had to manually download a pre-built EDK2 flash
device image (QEMU_EFI.fd) in order to boot this configuration with
QEMU. Now, the configuration is building EDK2 from source.

Signed-off-by: Dick Olsson <hi@senzilla.io>

Revision 3:

 * post-image.sh will now provide resized flash devices
 * readme.txt suggests pflash instead of bios

Revision 2:

 * Explicitly added the default EDK2 platform to defconfig
