From 3c016704d9c5418479e68e4690759cb2be6f90d3 Mon Sep 17 00:00:00 2001 From: ken kuo Date: Sat, 8 Jun 2013 11:14:09 +0800 Subject: nds32: Enable two banks of SDRAM on Andes board The original adp-ag101/adp-ag101p initialize only one bank(64MB) by default at boot time, but it is not enough for some application, so increasing to two banks(128M).
