But in set_efs_table, it has case for Stoneyridge. The boards also

When fetching antirollback information for the kernel, it is not always
known ahead of time what the current size of the kernel secdata area
is. If the incorrect size is passed, the TPM will return back the
correct size, but at the cost of an extra transaction; when using cr50
over I2C, this can be as much as 20ms. Currently, the first attempt uses
the minimium size (aka version 0 or 0.2), and if another size is used
(which is the case for all modern cr50-based boards, version 1 or 1.0),
then a transaction is wasted on every boot.
Therefore, change the default size sent to the TPM to be the default one
used in the VB2 API instead of the minimum one.

This patch adds cbfs_get_size() and cbfs_get_type() helper functions
(and _ro_ variations) to look up the size or type of a CBFS file without
loading it. Generally, use of these should be discouraged because that
tends to mean that the file needs to be looked up more than once, and
cbfs_alloc() or cbfs_type_load() are usually the more efficient
alternative... but sometimes they're unavoidable, so we might as well
offer them.
Also remove the <cbfs_private.h> header which had already become sort of
unnecessary with previous changes. cbfs_boot_lookup() is now exported in
<cbfs.h> for use in inlines, but should not be used directly by other
files (and is prefixed with an underscore to highlight that).
