Currently the code considers the absence of the NVRAM firmware
rollback space a a trigger for invoking the TPM factory initialization
sequence.
Note that the kernel rollback and MRC cache hash spaces are created
after the firmware rollback space. This opens an ever so narrow window
of opportunity for bricking the device, in case a startup is
interrupted after firmware space has been created, but before kernel
and MRC hash spaces are created.
The suggested solution is to create the firmware space last, and to
allow for kernel and MRC cache spaces to exist during TPM factory
initialization.

The TPM spaces created by the RO need to have different attributes
depending on the space's use. The firmware rollback counter and MRC
hash spaces are created by the RO code and need to be protected at the
highest level: it should be impossible to delete or modify the space
once the RO exits, and it is how it is done before this patch.
The rest of the spaces should be possible to modify or recreate even
after the RO exits. Let's use different set of NVRAM space attributes
to achieve that, and set the 'pcr0 unchanged' policy only for the
firmware counter and MRC cache spaces.
The definitions of the attributes can be found in "Trusted Platform
Module Library Part 2: Structures", Revision 01.16, section "13.2
TPMA_NV (NV Index Attributes)."
