From 37eac3f4609c4a6b7c8c3a2f4046fbc5deb07299 Mon Sep 17 00:00:00 2001 From: Prabhakar Kushwaha Date: Tue, 19 Jul 2016 15:54:33 +0530 Subject: [PATCH] armv8: ls1012a: Update Refresh cycle for DDR Refresh cycle value must be selected based on the frequency of DDR. tREFI = 7.8 us as per JEDEC. The value for MDREF[REF_CNT] should be based on round up (tREFI/tCK) formula. For 500MHz, mdref value should be 0x0f3c8000.
