commit a2dea87820ce5a52425bb3f088bd8590ced362f6 Author: Rudolf Marek r.marek@assembler.cz Date: Sun Nov 4 12:26:03 2012 +0100
Add the Asus F2A85-M
Add the Asus F2A85-M, while at it, add also SBxxx specific snippets which may be used by future boards. It contains handy stuff to enable the LPC decodes and also it enables clock output if SB clockchip is used.
