From: Uwe Hermann Date: Sat, 6 Nov 2010 23:36:49 +0000 (+0000) Subject: Various Super I/O fixes and corrections. X-Git-Url: http://wien.tomnetworks.com/gitweb/?p=coreboot.git;a=commitdiff_plain;h=8c02368e2d2e0574cf3999939f7cd26407cdf93a Various Super I/O fixes and corrections. - VIA VT1211: - Add missing LDNs and respective code to handle them. - Add some TODOs for other stuff that needs fixing. - Use VT1211_SP1 instead of hardcoding the LDN number (2). - Fixup pnp_dev_info[] as per datasheet, but some TODOs remain. - Various coding style fixes and changes to u8/u16/etc. - Serverengines Pilot: Various coding style fixes and changes to u8/u16/etc. Signed-off-by: Uwe Hermann Acked-by: Uwe Hermann git-svn-id: svn://svn.coreboot.org/coreboot/trunk@6030 2b7e53f0-3cfb-0310-b3e9-8179ed1497e1 --- diff --git a/src/superio/renesas/m3885x/superio.c b/src/superio/renesas/m3885x/superio.c index a6118b30c..1a5fbe627 100644 --- a/src/superio/renesas/m3885x/superio.c +++ b/src/superio/renesas/m3885x/superio.c @@ -44,15 +44,14 @@ static void m3885x_init(device_t dev) m3885_configure_multikey();
