Subject: [PATCH 1/4] firmware-utils: ptgen: add GPT support
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Add GPT support to ptgen, so we can generate EFI bootable images.
Introduced two options:
-g generate GPT partition table
-G GUID use GUID for disk and increase last bit for all partitions
We drop The alternate partition table to reduce size, This may cause
problems when generate vmdk images or vdi images. We must pad enough
sectors when generate these images.

Subject: [PATCH 2/4] grub2: split to grub2 and grub2-efi packages
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
EFI bootable images need grub2 host packages with efi platform,
but grub2 can not build efi platform and pc platform together,
so we split it to grub2 and grub2-efi packages.

Subject: [PATCH 3/4] x86: add EFI images and make iso images EFI bootable
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Add EFI bootable images for x86 platforms. These images can also
boot from legacy BIOS. And iso images can boot from EFI now.
EFI System Partition need to be fat12/fat16/fat32 (not need to load
filesystem drivers), so the first partition of EFI images are not ext4
filesystem any more.
GPT partition table has an alternate partition table, we did not
generate it. This may cause problems when use these images as qemu disk,
kernel can not find rootfs, we pad enough sectors will be ok.
