From beb0f2631fe6e49e86687cc3a7cf63ce41157a45 Mon Sep 17 00:00:00 2001 From: Edward O'Callaghan Date: Tue, 29 Apr 2014 13:09:50 +1000 Subject: [PATCH] superio/winbond/w83627hf: Avoid .c includes in mainboards MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Move towards the removal of the superio model specific xxx_serial_enable implementation. Make remaining superio romstage parts link-time symbols and fix corresponding mainboards to match. The following mainboards remain unconverted as they are ROMCC: - mainboard/supermicro/x6dai_g - mainboard/supermicro/x6dhe_g - mainboard/supermicro/x6dhr_ig - mainboard/supermicro/x6dhr_ig2 and so block the final removal of w83627hf_serial_enable(). Special cases: - mainboard/supermicro/h8qme_fam10: Provide local pnp_ sio func Provide local superio pnp_ programming entry/exit functions as to avoid making superio implementation global symbols. Although this is not the proper/final solution, it does mitigate possible symbol collisions and allow for continued superio refactorisation.
