It should be possible to generate a disk to a file using a loopback
device with mkefidisk.sh, which is useful for booting simulators. To
make this possible the partitions for the loop back need to work
similarly to the mmc devices. The mkfs.vfat also requires and
additional argument to force it to write to something other then a
real disk.
Example:
qemu-img create -f raw bigdisk 4G
dev=`sudo losetup -f`
sudo losetup $dev bigdisk
mkefidisk.sh $dev tmp-eglibc/deploy/images/qemux86/core-image-minimal-qemux86.hddimg /dev/sda
sudo losetup -d $dev
Note:
Also a bug was fixed in the mkefidisk.sh where if the disk you are
writing to initially has an invalid label the size of the first
partition will be computed incorrectly. For the simulator disk
creation this is generally always the case, but this can happen with
real hardware as well.

Some automounters are rather overzealous and like to mount things
immediately after partitioning. This can happen if the disk is being
reused and the partitions align exactly with the existing partitions
which have already been formatted. Move the unmount code into a function
and call it before and after partitioning.

With automounters abounding it makes more sense to attempt to unmount
the device rather than abort, just like ddimage does.

While GPT works fine when writing to actual media, it cannot be reliably
used for distributing disk images as it requires the backup table to be
on the last block on the device, which of course varies from device to
device. Use MSDOS tables instead.
Use mkfs to label the filesystems as msdos tables do not support
partition labeling.

Most firmware implementations use the EFI specified
EFI/BOOT/bootia32.efi (and similar) boot paths. Only broken firmware
uses different paths for removable media. In those cases, the user can
add their own startup.nsh.
For the compliant case, selecting "Shell" from the EFI boot menu should
go to the shell.

Without a reliable way of knowing if the target device with be an
asyncronous block device on the target (MMC or USB), err on the side of
caution of always specifcy "rootwait", ensuring the kernel will wait for
the device to appear and not abort if it hasn't appeared in time for
mount.
Document the remaining kernel parameters added by this script on the
same line as rootwait.

There is no need to boot with "rw". Booting with "ro" will allow for
fsck to be run during boot, and a proper /etc/fstab will still ensure
the rootfs is "rw" by the time the user can interact with the system.
Change the "rw" to "ro" in the kernel parameters specified in the
generated grub.cfg file.
Fixes [YOCTO 4036] mkefidisk.sh hardcodes 'rw' as root mount option

The current script only replaces an existing root= kernel parameter
which can result images created without a root= paremeter, even though
the script expects a target rootfs parameter.
Rather than replacing the root= parameter, delete the root= parameter if
it exists, then append an appropriate root= parameter.
Fixes [YOCTO 4035] mkefidisk.sh forgets to add root= parameter

The script was creating a FAT fs with EFI files in it, but wasn't setting the GPT GUID.
Using 'gummiboot install' natively failed because of the missing GPT GUID, so fix that. While we're there also set the name to "EFI System Partition".

The script greps for 'Disk', which doesn't work when your crazy Dutch distro has parted call it 'Schijf', so force LANG=C.
The second problem is that 'Disk' might be a substring in the Model entry:

Sometimes it is convenient to prepare a bootable image from the
host rather than using a live-image to install to a disk on the
target.
This script takes a live image as input, partitions a device, and
performs the installation just as the installer would if run on
the target.
