From e5d310b349b2cbcc0dab31139c92201f332695bb Mon Sep 17 00:00:00 2001 From: Brent Casavant Date: Tue, 21 Jun 2005 17:16:01 -0700 Subject: [PATCH] ioc4: CONFIG split The SGI IOC4 I/O controller chip drivers are currently all configured by CONFIG_BLK_DEV_SGIIOC4. This is undesirable as not all IOC4 hardware features are needed by all systems. This patch adds two configuration variables, CONFIG_SGI_IOC4 for core IOC4 driver support (see patch 1/3 in this series for further explanation) and CONFIG_SERIAL_SGI_IOC4 to independently enable serial port support.
