From a348226cd2f1e87f82d2489e8b04b665cd0fcc20 Mon Sep 17 00:00:00 2001 From: hauke Date: Fri, 20 Feb 2009 16:19:46 +0000 Subject: [atheros]: move files for kernel 2.6.26 to a special directory. In kernel 2.6.28 the directory structure has chanced, so for kernel 2.6.26 a own files directory is needed. git-svn-id: svn://svn.openwrt.org/openwrt/trunk@14583 3c298f89-4303-0410-b956-a3cf2f4a3e73 --- .../include/asm-mips/mach-atheros/ar531x.h | 149 +++++++++++++++++++++ 1 file changed, 149 insertions(+) create mode 100644 target/linux/atheros/files-2.6.26/include/asm-mips/mach-atheros/ar531x.h (limited to 'target/linux/atheros/files-2.6.26/include/asm-mips/mach-atheros/ar531x.h') diff --git a/target/linux/atheros/files-2.6.26/include/asm-mips/mach-atheros/ar531x.h b/target/linux/atheros/files-2.6.26/include/asm-mips/mach-atheros/ar531x.h new file mode 100644 index 000000000..8148b76fb --- /dev/null +++ b/target/linux/atheros/files-2.6.26/include/asm-mips/mach-atheros/ar531x.h @@ -0,0 +1,149 @@ +#ifndef __AR531X_H +#define __AR531X_H + +#include +#include +#include +#include +#include + +#if (LINUX_VERSION_CODE >= KERNEL_VERSION(2,6,24)) +extern void (*board_time_init)(void); +#endif + +/* + * Atheros CPUs before the AR2315 are using MIPS 4Kc core, later designs are + * using MIPS 4KEc R2 core.
