28.4.7 Cache Tag Storage (FMC_TAGVDW3Sn)
The cache is a 4-way, set-associative cache with 8 sets. The ways are numbered 0-3 and
the sets are numbered 0-7. In TAGVDWxSy, x denotes the way, and y denotes the set.
This section represents tag/vld information for all sets in the indicated way.

28.4.8 Cache Data Storage (upper word) (FMC_DATAW0SnU)
The cache of 64-bit entries is a 4-way, set-associative cache with 8 sets. The ways are
numbered 0-3 and the sets are numbered 0-7. In DATAWxSyU and DATAWxSyL, x
denotes the way, y denotes the set, and U and L represent upper and lower word,
respectively. This section represents data for the upper word (bits [63:32]) of all sets in
the indicated way.
