From 1da177e4c3f41524e886b7f1b8a0c1fc7321cac2 Mon Sep 17 00:00:00 2001 From: Linus Torvalds Date: Sat, 16 Apr 2005 15:20:36 -0700 Subject: Linux-2.6.12-rc2 Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip! --- include/asm-arm/hardware/locomo.h | 206 ++++++++++++++++++++++++++++++++++++++ 1 file changed, 206 insertions(+) create mode 100644 include/asm-arm/hardware/locomo.h (limited to 'include/asm-arm/hardware/locomo.h') diff --git a/include/asm-arm/hardware/locomo.h b/include/asm-arm/hardware/locomo.h new file mode 100644 index 000000000000..5f10048ec54e --- /dev/null +++ b/include/asm-arm/hardware/locomo.h @@ -0,0 +1,206 @@ +/* + * linux/include/asm-arm/hardware/locomo.h + * + * This file contains the definitions for the LoCoMo G/A Chip + * + * (C) Copyright 2004 John Lenz + * + * May be copied or modified under the terms of the GNU General Public + * License.
