Update the ddimage script to allow it to work on Mac OS too. The biggest
difference is sysfs vs diskutil and in the syntax of the stat command
between Mac OS and Linux, unfortunately. Workarounds using ls, cut, and
columns got really fragile really quickly. Relying on stat and switching
on uname seemed the more robust solution.

When running automated tests (or just generally interacting with)
boards whose serial console devices are on the board itself and thus
disappear when powered down or practically disconnected, such as the
BeagleBone white, some terminal programs (e.g. picocom) will exit when
the device disappears and need to be restarted after the serial device
returns. This script handles this automatically for such terminal
programs.

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.

oe-core removed the prerequisite to have sh as bash. POSIX doesn't define
any options and furthermore allows 'echo -e' to be the default behavior.
This means that in dash 'echo -e' will actually print '-e' and interpret
backslashes by default. We use instead 'printf' builtin command with or
without '\n' to simulate 'echo -e' or 'echo -n'.
'printf' needs format while 'echo' can be used without any arguments. So
'echo >' was replaced by 'printf "" >'.
'echo' without '-n' flag adds a new line by default so to keep the same
behavior of two new lines while using 'echo "\n"', 'printf "\n\n"' is
used.
