[PATCH] Support for Asus M4A78-EM mainboard

[Juhana Helovuo]

Hello,

Here is a patch to get Asus M4A78-EM supported and booting Linux.

Files attached are:

* Boot log with the patches applied.

* Board-specific patch for SVN 6139

* Resend of Myles Watson's patch for AMD Northbridge, because the 
original did not work for me without manual editing. It is also needed 
for booting Linux.

Before applying the patch, the board directory should be created with

% svn cp src/mainboard/asus/m4a785-m src/mainboard/asus/m4a78-em
