Details
mountinfo provides information about mounts in the process's mount namespace.
mountinfo is provided by proc_namespace.ko. See also mounts, mountstats and the mount_namespaces(7) man page.
Excerpt from the proc(5) man page:
/proc/[pid]/mountinfo (since Linux 2.6.26)
This file contains information about mounts in the
process's mount namespace (see mount_namespaces(7)). It
supplies various information (e.g., propagation state,
root of mount for bind mounts, identifier for each mount
and its parent) that is missing from the (older)
/proc/[pid]/mounts file, and fixes various other problems
with that file (e.g., nonextensibility, failure to
distinguish per-mount versus per-superblock options).
The file contains lines of the form:
36 35 98:0 /mnt1 /mnt2 rw,noatime master:1 - ext3 /dev/root rw,errors=continue
(1)(2)(3) (4) (5) (6) (7) (8) (9) (10) (11)
The numbers in parentheses are labels for the descriptions
below:
(1) mount ID: a unique ID for the mount (may be reused
after umount(2)).
(2) parent ID: the ID of the parent mount (or of self for
the root of this mount namespace's mount tree).
If a new mount is stacked on top of a previous
existing mount (so that it hides the existing mount)
at pathname P, then the parent of the new mount is
the previous mount at that location. Thus, when
looking at all the mounts stacked at a particular
location, the top-most mount is the one that is not
the parent of any other mount at the same location.
(Note, however, that this top-most mount will be
accessible only if the longest path subprefix of P
that is a mount point is not itself hidden by a
stacked mount.)
If the parent mount lies outside the process's root
directory (see chroot(2)), the ID shown here won't
have a corresponding record in mountinfo whose mount
ID (field 1) matches this parent mount ID (because
mounts that lie outside the process's root directory
are not shown in mountinfo). As a special case of
this point, the process's root mount may have a
parent mount (for the initramfs filesystem) that lies
outside the process's root directory, and an entry
for that mount will not appear in mountinfo.
(3) major:minor: the value of st_dev for files on this
filesystem (see stat(2)).
(4) root: the pathname of the directory in the filesystem
which forms the root of this mount.
(5) mount point: the pathname of the mount point relative
to the process's root directory.
(6) mount options: per-mount options (see mount(2)).
(7) optional fields: zero or more fields of the form
"tag[:value]"; see below.
(8) separator: the end of the optional fields is marked
by a single hyphen.
(9) filesystem type: the filesystem type in the form
"type[.subtype]".
(10) mount source: filesystem-specific information or
"none".
(11) super options: per-superblock options (see mount(2)).
Currently, the possible optional fields are shared,
master, propagate_from, and unbindable. See
mount_namespaces(7) for a description of these fields.
Parsers should ignore all unrecognized optional fields.
For more information on mount propagation see:
Documentation/filesystems/sharedsubtree.txt in the Linux
kernel source tree.

The (main/scrpn/boot/arm/prx/atom/rtl) label in the Model column shows which CPU is meant for Multi-Linux models.
Note that this list comes from Supportdata2 probes, which can have arbitrary settings and come from different firmware versions.
It doesn't say much if a model is not listed here. It may be a missing supportdata2 file or just a disabled feature.
