[<rob...@us...>]

Update of /cvsroot/gc-linux/linux/drivers/exi
In directory sc8-pr-cvs1.sourceforge.net:/tmp/cvs-serv17179/drivers/exi

Modified Files:
	gcn-exi-lite-tmbinc-exi_c.c 
Log Message:
Added the SD and MMC card driver (alpha)
Modified gcn-exi-lite-tmbinc-exi_c.c to output 0xff's upon *reading* 
from the exi bus, instead of outputting semi-random data. 
This is a requirement to meet the SD spec, and should not influence
other drivers using the exi framework
