[U-Boot] [PATCH 1/9] ddr: altera: Configuring SDRAM extra cycles timing parameters

Chin Liang See clsee at altera.com
Thu Sep 15 09:26:44 CEST 2016 

To enable configuration of sdr.ctrlcfg.extratime1 register which enable
extra clocks for read to write command timing. This is critical to
ensure successful LPDDR2 interface
