Get rid of early_serial, it is now a generic function in early_init.
Add some more enables to the s1850. Signed-off-by: Ronald G. Minnich <rminnich@gmail.com> Acked-by: Stefan Reinauer <stepan@coresystems.de> git-svn-id: svn://svn.coreboot.org/coreboot/trunk@4736 2b7e53f0-3cfb-0310-b3e9-8179ed1497e1
