bool "Support 256KB OCRAM"
depends on MX6D || MX6Q
help
Allows using the full 256KB size of the OCRAM on the MX6Q/MX6D series
of chips, such as for SPL. The OCRAM of the Lite series of chips is
only 128KB, so using this option will prevent the resulting code from
working on those chips.

help
Say "Y" if your board uses dynamic (per-boot) DDR calibration.
If unsure, say N.
