From 463ec1caa3cb9401da8f788fc7d4eee08a5f0edc Mon Sep 17 00:00:00 2001 From: Vladimir Zapolskiy Date: Thu, 19 Apr 2012 04:33:10 +0000 Subject: devkit3250: add Timll DevKit3250 board initial support This change adds a basic support for Embest/Timll DevKit3250 board, NOR and UART are the only supported peripherals for a moment. The board doesn't require low-level init, because the initial SDRAM and GPIO configuration is performed during kickstart bootloader execution.
