From 2ac07f75d1977008e829d00bcce16143e171765d Mon Sep 17 00:00:00 2001 From: David Lechner Date: Fri, 26 Feb 2016 00:46:07 -0600 Subject: arm: Add support for LEGO MINDSTORMS EV3 This is based on the davinci da850evm. It can boot from either the on-board 16MB flash or from a microSD card. It also reads board information from an I2C EEPROM. The EV3 itself initally boots from write-protected EEPROM, so no u-boot SPL is needed.
