Subject[PATCH 6/7] edac: mpc85xx fsb ecc
From: Konstantin Olifer <kolifer@gmail.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.
