Ensure No Unnecessary Errors During Code Update

This commit fixes the problem of partitions that have
either been deleted or had their name changed. The partitions
are only preserved if they exist in both the running and
read only directories, otherwise, they are skipped and the
error is not triggered.

Tested:
Performed code update and verified that there were no errors
called.

Preserved Partition Change

This commit fixes the problem of corrupted or changed preserved
partitions. If one of the partitions becomes corrupted, or it
the size of the partition needs to be changes, these changes will
allow for the copying of the old partition, forcing the new one
to take its place.

Tested:
When a PRESERVED partition is altered (corrupted or contents
deleted) ensured that the contents was not copied into the
prsv directory and the working partition appeared upon
reboot.

openpower: mmc: physical reset triggers bios reset

The service openpower-bios-factory-reset runs during startup and
calls bios_reset_check. This method determines whether the
factory-reset-toggle gpio has changed since the last reboot and
triggers a bios reset if it has. This decouples the code to check
for bios resets from the code in item_updater_mmc::reset and from
the BMC factory reset code.

Tested: Verified that the reset-gpio-val file was created to store
the previous value of the environment variable rwreset. Added files
to /media/hostfw and verified that they were removed upon reboot
when the value in reset-gpio-val differed from rwreset.

mmc: Handle missing pnor.toc file

The pnor.toc file is a mboxd implemenation, and therefore will not exist
once the host uses PLDM instead, which uses .lid files instead of pnor
partition files. As part of the transition, the pnor.toc file is being
built into a .lid file for images that do not contain pnor partition
files. Handle this transition by creating a symlink from pnor partition
file to .lid file. This would remain in place until all the PLDM support
from the hostboot side is in place and mboxd is removed.

Tested: Verified rainier powers on and mboxd starts successfully, and
the volatile partition gets cleared.

mmc: Copy only LID files during update

This is one step closer in replacing the PNOR partition files with LID
files:
- During an update, only copy LID files to the read-write directory. The
update-bios-attr-table service will create symlinks from PNOR
partition files to LID files.
- Use the pnor.toc from the read-only directory to get the list of
preserved partitions, since there won't be a pnor.toc file in the
read-write directory anymore. A future commit will read the PLDM file
table to determine which LID files to preserve.
- Preserve the symlink target (LID file) instead of the symlink name
(partition file name), otherwise the symlink gets broken if we copy a
file that was a symlink.

Tested: Verified after code update that all the partition files were
symlinks to a LID file, and a subsequent update preserved the LID files
that correspond to the preserved partitions.

item_updater_mmc: Implement bios factory reset

Implemented the method ItemUpdaterMMC::reset. It clears files in
/media/hostfw/ related to managing console and virtualization
information, then recreates those files using bus calls to service
files. Added checks to obmc-flash-bios so it doesn't cause problems
when its methods are run multiple times. Modified latest services to
allow them to run more than once. Services which depend on the init
service will run after it.

Tested: Created extra files in the directories that the reset method
removes. Called the reset method using busctl. Verified that the
added files were removed and that the removed files that belong were
recreated. Verified that all services called were run.

mmc: Move process host firmware to own service

The process-host-firmware subcommand waits for the Entity Manager
interface to appear in D-Bus. It's currently run from the mmc-init
script. But if a system does not support Entity Manager, then the init
service never exits, blocking its dependencies like PLDM from starting.

Move the process-host-firmware to its own service file so that if needs
to wait forever, it doesn't interfere with other processes. Need to
start it after the mmc-init so that all the directories are setup before
the symlinks are created.

Tested: Verified on tacoma that the service remains running and PLDM
starts successfully. Verified on rainier that the symlinks are created.

Also don't delete patches when updating the running version
because it's not known if it's just a side switch. This should

mmc: Add read-only directory to support mboxd

The mboxd implementation assumes that there is a read-only and
read-write directory. During a write request, mboxd copies the
contents of the read-only to the read-write directory. To continue
to support mboxd, mount a read-only directory of the hostfw image
for mboxd to use. Otherwise the write command fails (can't copy
the file to itself) and mboxd exits.

Tested: Verified mboxd didn't fail and system powered on.

mmc: Setup hostfw directories

The BMC updater will take care of writing the new hostfw image
to flash since it's delivered in the single tarball file, but
when the BMC starts up, need to setup the directories so that
the contents of the host FW are visible to consumers like pldm.

The first service is to setup the patch directory. This is
similar to UBI. The path that mboxd expects (pnor) will point to
a directory in the hostfw partition. Then create a similar
symlink (hostfw) for pldm to use. Eventually pldm will replace
mboxd.

The second service is an init setup. We need to make the 2 hostfw
versions visible. The secondary (non-running) will just be a
read-only mount of the non-running image. The primary (running)
version needs to be read-write. The mboxd code currently
handles 3 directories: ro, rw, prsv. This was deemed too complex
for pldm to replicate, so it was decided to have a single rw
directory, then pldm would determine if it allowed a write or not.
To handle the preserved files (that are not updated on an update),
need to copy them off to a tmp space, then set up the primary
directory with the contents of the running image, then restore the
preserved files. Currently only the PNOR contents are preserved,
at a later point the pldm files will be preserved and a different
list like the pnor.toc file will be added.

Finally, like the vpnor util does, if the version has changed on,
remove the patch files. Just that we need to do this when the init
service starts because the symlinks will not change at runtime
(the host fw version is tied to the bmc version).
