From 728b393f3b012ac46505151b80af1d4334786845 Mon Sep 17 00:00:00 2001 From: Bin Meng Date: Wed, 4 Feb 2015 16:26:12 +0800 Subject: x86: Add SPI support to quark/galileo The Quark SoC contains a legacy SPI controller in the legacy bridge which is ICH7 compatible. Like Tunnel Creek and BayTrail, the BIOS control register offset in the ICH SPI driver is wrong for the Quark SoC too, unprotect_spi_flash() is added to enable the flash write.
