From 472e0393eb1a8f212994f7152daa4eb5e8554ef3 Mon Sep 17 00:00:00 2001 From: Tom Warren Date: Wed, 30 Jul 2014 16:26:21 -0700 Subject: ryu: Add mainboard_init_xxx functions to get it building again Rush has its EC on SPI, and Ryu has it on I2C, so need both mainboard_init_ec_spi and mainboard_init_ec_i2c in both builds, due to romstage.c being in the common tegra132 subdir. BUG=none BRANCH=rush_ryu TEST=Built both rush and rush_ryu images OK. Will try to boot on Ryu later.
