initfs: update: check individual mtd partitions for mounts

Instead of checking for any mtd device, only check mtd devices
that are to be updated.  Include child mtd devices when looking
for mounted filesystems.

If this check is suppressed flash updates are suppressed.
Suppressing the check may be useful to verify a update could
succeed at shutdown.

Build Status


OpenBMC uses Yocto/Open-Embedded for a build system, which supports an out-of-tree build. It is recommended that you create an empty directory somewhere to hold the build. This directory will get big.

On Ubuntu 14.04 the following packages are required to build the default target

sudo apt-get install -y git build-essential libsdl1.2-dev texinfo gawk chrpath diffstat

On Fedora 23 the following packages are required to build the default target:

sudo dnf install -y git patch diffstat texinfo chrpath SDL-devel bitbake
sudo dnf groupinstall "C Development Tools and Libraries"

To start a build:

cd <builddir>
. <repodir>/openbmc-env
bitbake obmc-phosphor-image
