From: Vitaly Bordug Date: Sat, 17 Sep 2005 02:28:00 +0000 (-0700) Subject: [PATCH] ppc32: Add ppc_sys descriptions for PowerQUICC I devices X-Git-Tag: v2.6.14-rc2~5^2~30 X-Git-Url: http://pilppa.com/gitweb/?a=commitdiff_plain;h=514ccd4e6c414d8064d53235f7fc09fc02ec2078;p=linux-2.6-omap-h63xx.git [PATCH] ppc32: Add ppc_sys descriptions for PowerQUICC I devices Added ppc_sys device and system definitions for PowerQUICC I devices. This will allow drivers for PQI to be proper platform device drivers. Currently sys section contains only MPC885 and MPC866. Identification should be done with identify_ppc_sys_by_name call, with board-specific "name" string passed, since PQI do not have any register that could identify the SOC.
