They are doing the same things: create live images, merge them into one
bbclass makes it easy to understand.

when we generate hddimage and use it to prepare SD card
using scripts/contrib/mkefidisk.sh as described here
http://elinux.org/Minnowboard:MinnowMaxYoctoProject
The content of startup.nsh contains
bootx64.efi
but this file is actually not in same dir as startup.nsh
its in /EFI/BOOT so for this to work entry in startup.nsh
should be
fs0:\EFI\BOOT\bootx64.efi
Otherwise the image is D-O-A

As mentioned when introducing the VM images
(https://bugzilla.yoctoproject.org/show_bug.cgi?id=7374), the
resulting images only work when the image is mounted as a disk that
results in the hard-coded path (/dev/sda in the current
default). Using the file system UUID to find the rootfs is more
flexible.
To enable this for boot-direct.bbclass and thus image-vm.bbclass (aka
FSTYPEs vdi/vmdk/qcow2), set SYSLINUX_ROOT =
"root=UUID=<<uuid-of-rootfs>>". The rootfs image must use an ext file
system.
The special string will get replaced in the APPEND line with the
actual UUID when the boot loader (grub-efi, syslinux or gummiboot)
writes the boot loader configuration files. At that time, the rootfs
image has already been created and its UUID can be extracted using
"tune2fs -l", which also should be available because the
e2fsprogs-native tools were needed to create the image in the first
place.

Add MLPREFIX to depends flag to ensure the correct gummiboot is
dependended upon.

Adds a gummiboot class similar to grub-efi class and makes the necessary
changes so it can be used for live/hddimg images as well.
One can set EFI_PROVIDER = "gummiboot" in local.conf to use gummiboot instead of grub-efi.
Gummiboot requires some kernel options that are not enabled by default, so one has to build
with KERNEL_FEATURES_append = " cfg/efi-ext".
The install scripts have been updated too, keeping the old behaviour around,
but accounting for the new boot loader config files (if they exist).
It can be argued that the installer and bootimg are a bit wierd and not necessarily correct,
but I wanted to have the exact same behviour with gummiboot.
With the default EFI_PROVIDER = "grub-efi" nothing changes, everthing should be just as before.
I've tested live boot, install and normal boot on:
- FRI2
- genericx86-64 on NUC
with:
EFI_PROVIDER = "gummiboot"
KERNEL_FEATURES_append = " cfg/efi-ext"
in local.conf.
