Add PC87382 support
This patch adds support for NSC PC87382 Super I/O. It is used in many Lenovo Notebooks as Docking LPC Switch. v2 because of: - Skip some empty files - Fix newlines in Kconfig and Makefile.inc - chip.h missed uart8250.h include - add the Kconfig option in sorted order Thanks to idwer on irc for pointing that out. Signed-off-by: Sven Schnelle <svens@stackframe.org> Acked-by: Peter Stuge <peter@stuge.se> git-svn-id: svn://svn.coreboot.org/coreboot/trunk@6332 2b7e53f0-3cfb-0310-b3e9-8179ed1497e1
