Subject: [PATCH 6/7] edac: mpc85xx fsb ecc

From: Konstantin Olifer <kolifer@...il.com>

Patch is for Kernel 2.6.33. e752x_edac suppose that fsb ECC exist, for example, on
Celeron + 3100. That is wrong. 
ECC FSB supported only on Xeon for our vision (www.setdsp.ru) and datasheet from developer intel www. 
Fixed.
