Depending on the value programmed into the SDRAM_TYPE field of the
EMIFF SDRAM operation register, either the ac parameters for SDRAM or the
ac parameters for mobile DDR are supported; that is, the SDRAM frequency
field is decoded into the values in either Table 33 or Table 34, not both. See
section 3.3.7 for more information.
