From de3ac0f7f2326933a2b81eae8c18e09c312c9d00 Mon Sep 17 00:00:00 2001 From: stefanct Date: Fri, 25 Oct 2013 00:33:37 +0000 Subject: Refactor Intel Chipset Enables. - Combine enable_flash_ich_4e() and enable_flash_ich_dc() to enable_flash_ich_fwh(). - Remove unjustified (chipset) name parameters from various enable_flash_ich* functions. - Make Poulsbo and Tunnel Creek use generic enables by refining existing functions to work with them, including everything in ichspi.c. - Refactor enable_flash_ich_fwh_decode() to be called unconditionally for all chipsets. - Add support for Intel Atom Centerton (S12x0). - Recombine ICH2/3/4/5 to CHIPSET_ICH2345 because we treat them equally anyway. - Move spibar handling out of ich_init_spi() into enable_flash_ich_spi() - Various small cleanups.
