From 0241c3131dd4c19a1116c863d622358eb2680462 Mon Sep 17 00:00:00 2001 From: Alexey Brodkin Date: Thu, 9 Apr 2015 19:50:58 +0300 Subject: board: axs10x - support v3 mother-board There're 2 versions of motherboards that could be used in ARC SDP. The only important difference for U-Boot is different NAND IC in use: [1] v2 board (we used to support up until now) sports MT29F4G08ABADAWP while [2] v3 board sports MT29F4G16ABADAWP They are almost the same except data bus width 8-bit in [1] and 16-bit in [2]. And for proper support of 16-bit data bus we have to pass NAND_BUSWIDTH_16 option to NAND driver core - which we do now knowing board type we're running on.
