[coreboot] s2892 and s2895 buildrom patch

[Myles Watson]

This patch adds support for Tyan s2892 and s2895 to buildrom.

First do this:

svn cp config/platforms/tyan-s2891.conf config/platforms/tyan-s2892.conf
svn cp config/platforms/tyan-s2891.conf config/platforms/tyan-s2895.conf
svn cp packages/kernel/conf/defconfig-tyan-s2881
packages/kernel/conf/defconfig-tiny-2.6.22
svn cp packages/kernel/conf/defconfig-serengeti_cheetah-x86_64
packages/kernel/conf/defconfig-tiny-2.6.22-x86_64
svn cp packages/kernel/tyan-s2891.mk packages/kernel/tiny-2.6.22.mk
svn cp packages/filo/conf/tyan-s2891-Config
packages/filo/conf/tyan-generic-Config
svn cp packages/coreboot-v2/tyan-s2891.mk packages/coreboot-v2/tyan-generic.mk

Then apply the patch.  It kept it a lot shorter.  I tried to only
create specialized files where needed.  That's why there's a
tyan-generic.mk and a tyan-generic-Config.  Especially now that we
have make kernel-config and friends it doesn't seem like we need so
many files for every added platform.
