From a904f9ef691062a43baa5542cf63daed45a1185a Mon Sep 17 00:00:00 2001 From: Hung-Te Lin Date: Thu, 11 Apr 2013 15:58:12 +0800 Subject: ec/google: Isolate EC bus protocol implementation. The Chrome EC can be connected by different types of bus like LPC / I2C / SPI, and the current implementation is only for LPC. To support other types, we must first isolate the LPC protocol stuff and add configuration variable (EC_GOOGLE_CHROMEEC_LPC) to specify bus type. Verified by building google/link (with chromeec) configuration successfully.
