Do we need to care about other DDR speeds than 2133?

[lbmeng]

build/Makefile defines DDR_SPEED as 2133, but lists some other possible speeds

#DDR_SPEED 1:1600. 2:2133 3:2800 4 :3200
DDR_SPEED = 2133

I believe these are all supported speeds by the DDR controller on the JH7100 SoC.

When upstream, do we need to care about other possible DDR speeds the SoC supports? Or do we plan to create board variants that have a different DRAM chip mounted with different frequency?

@MichaelZhuxx could you please check with the SoC team about these questions from @lbmeng?

Recommend only use 2133 as major DDR speed after discuss with SoC team @pdp7 @lbmeng

Thanks @MichaelZhuxx for the clarification.
