ARM DDI0198D
The line length of the cache is determined by the Len field. The Len field is bits [13:12]
for the DCache and bits [1:0] for the ICache. Table 2-9 shows the line length encoding.
The cache type register values for an ARM926EJ-S processor with the following
configuration are shown in Table 2-10:
