From: Brent Casavant Date: Wed, 22 Jun 2005 00:16:01 +0000 (-0700) Subject: [PATCH] ioc4: CONFIG split X-Git-Tag: v2.6.13-rc4~130^2~202^2~83 X-Git-Url: http://pilppa.com/gitweb/?a=commitdiff_plain;h=e5d310b349b2cbcc0dab31139c92201f332695bb;p=linux-2.6-omap-h63xx.git [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.
