From 272c5265ed8f4bf1f02f2d2b38828fbf8939cac3 Mon Sep 17 00:00:00 2001 From: Yuan Yao Date: Fri, 17 Oct 2014 15:26:34 +0800 Subject: [PATCH] ls102xa: ifc: nor: fix the write issue when bytes unaligned Add define CONFIG_SYS_WRITE_SWAPPED_DATA. For LS1021AQDS and LS1021QTWR nor flash write should swap the bytes when handle unaligned tail bytes. Because of the ending, if the date bus width is 16-bits and the number of bytes is odd, we should swap the byte when write the last one.
