From 267dbb74d28e4d5d13e892488563ab439398513d Mon Sep 17 00:00:00 2001 From: Randall Spangler Date: Thu, 27 Jun 2013 13:06:19 -0700 Subject: Add common interface to EC flash commands ectool and burn_my_ec need to use the same lower-level interface to the EC flash commands, rather than duplicating calling the low-level flash read/write/erase commands. This is a precursor to refactoring the low-level commands to support SPI/STM32L in a follow-up CL.
