From c995f3a3c5263c2e424064fac81f169846b6d25e Mon Sep 17 00:00:00 2001 From: Masahiro Yamada Date: Sat, 28 Jan 2017 06:53:44 +0900 Subject: [PATCH] ARM: uniphier: use gd->bd->bi_dram for memory reserve on LD20 SoC For LD20 SoC, the last 64 byte of each DRAM bank is used for the dynamic training of DRAM PHY. The regions must be reserved in DT to prevent the kernel from using them. Now gd->bd->bi_dram reflects the actual memory banks. Just use it instead of getting access to the board parameters.
