From cf7b4989083cb3fd1adf34dc5e07d4ac253e8f85 Mon Sep 17 00:00:00 2001 From: Edward O'Callaghan Date: Wed, 23 Apr 2014 21:52:25 +1000 Subject: superio/fintek/*: Factor out generic romstage component The romstage of Fintek Super I/O's is identical, leading to replication of essentially the same code prone to bitrot. Herein we consolidate the early pre-ram UART initialisation code into fintek/common, rather we leave the exceptions to be implemented under model/. More precisely we provide a well documented version of early_serial.c under fintek/common and select by way of Kconfig as a generic romstage component to Super I/O support. We leave future Super I/O's the option to implement `non-standard` initialisation code should such a (unlikely) need araise. A primary advantage is that new support for romstage serial is now trival to add. We also provide some Kconfig documentation while here.
