interesting behavior, i thought svn could do moves.
the result should be ok though.. the purpose is dropping the old i82801er southbridge code and using the ich5r code instead because its the same chip but the code looks more solid and is used by many more systems. Some of the old i82801er features have been ported (like hpet enable) git-svn-id: svn://svn.coreboot.org/coreboot/trunk@2241 2b7e53f0-3cfb-0310-b3e9-8179ed1497e1
