Stefan Agner a19797b22c colibri_imx7: improve DDR3 timing ... This makes sure that all Colibri iMX7 modules work with the same timing. The changes are: - Disable ODT on read (JEDEC standard JESD79-3F says in chapter 5.2.3 ODT during Reads: "As the DDR3 SDRAM can not terminate and drive at the same time, RTT must be disabled at least half a clock cycle..." and also MX7D SABRESD is disabling it) This alone fixed memory issues for two Colibri iMX7 1GB modules which showed issues before - Make sure tRFC(min) is at least 260ns - Make sure tRC is >50.625ns - tRP needs to be >13.125ns, we can lower from 18.75ns to 15ns - tFAW is not relevant, leave at reset Signed-off-by: Stefan Agner <stefan.agner@toradex.com> Acked-by: Marcel Ziswiler <marcel.ziswiler@toradex.com>		2018-07-23 10:56:38 +02:00
