Subject: 85xx: Show DDR memory data rate in addition to the memory clock frequency.
X-Git-Tag: v1.3.3-rc1~123^2~6
X-Git-Url: https://git.librecmc.org/?a=commitdiff_plain;h=e9ea679918fbc9a53fa2f2a904aac874ea736036;p=oweals%2Fu-boot.git

85xx: Show DDR memory data rate in addition to the memory clock frequency.

Show the DDR memory data rate in addition to the memory clock
frequency.  For DDR/DDR2 memories the memory data rate is 2x the
memory clock.
