From d67e76568acff164328467a744a76de62b67f026 Mon Sep 17 00:00:00 2001 From: Eric Biederman Date: Fri, 28 May 2004 14:18:45 +0000 Subject: - Added volatile to asm statements in auto.c and failover.c - Updated the romcc version in Config.lb - Fixed type sizes in romcc_io.h and io.h inl() returning a byte was nasty git-svn-id: svn://svn.coreboot.org/coreboot/trunk@1583 2b7e53f0-3cfb-0310-b3e9-8179ed1497e1 --- src/arch/i386/include/arch/io.h | 12 ++++---- src/arch/i386/include/arch/romcc_io.h | 54 ++++++++++++++++++++++++++++------- 2 files changed, 49 insertions(+), 17 deletions(-) (limited to 'src/arch/i386') diff --git a/src/arch/i386/include/arch/io.h b/src/arch/i386/include/arch/io.h index c1207b3182..411098128f 100644 --- a/src/arch/i386/include/arch/io.h +++ b/src/arch/i386/include/arch/io.h @@ -11,34 +11,34 @@ */ #ifdef __ROMCC__ -static void outb(unsigned char value, unsigned short port) +static inline void outb(uint8_t value, uint16_t port) { __builtin_outb(value, port);
