From 66ab3a74c5ce737effc2c64391e036b0938b1c36 Mon Sep 17 00:00:00 2001
From: Jesper Nilsson <jesper.nilsson@axis.com>
Date: Tue, 21 Apr 2009 11:44:57 +0200
Subject: [PATCH 1/4] CRIS: Merge machine dependent boot/compressed and
 boot/rescue

Merge the machine dependent boot directories for v10 and v32.
This avoids some code duplication and eases the way for further
merging later on.

-Creation of the self-extracting compressed kernel image (vmlinuz)
------------------------------------------------------------------
-$Id: README,v 1.1 2001/12/17 13:59:27 bjornw Exp $
-
-This can be slightly confusing because it's a process with many steps.
-
-The kernel object built by the arch/etrax100/Makefile, vmlinux, is split
-by that makefile into text and data binary files, vmlinux.text and 
-vmlinux.data.
-
-Those files together with a ROM filesystem can be catted together and
-burned into a flash or executed directly at the DRAM origin.
-
-They can also be catted together and compressed with gzip, which is what
-happens in this makefile. Together they make up piggy.img. 
-
-The decompressor is built into the file decompress.o. It is turned into
-the binary file decompress.bin, which is catted together with piggy.img
-into the file vmlinuz. It can be executed in an arbitrary place in flash.
-
-Be careful - it assumes some things about free locations in DRAM. It
-assumes the DRAM starts at 0x40000000 and that it is at least 8 MB,
-so it puts its code at 0x40700000, and initial stack at 0x40800000.

Subject: [PATCH 4/4] CRISv32: Fix typo compile error in ARTPEC-3 gpio driver.

arch/cris/arch-v32/drivers/mach-a3/gpio.c:
+spin_lock_irqrestore(&gpio_lock, flags);
arch/cris/arch-v32/drivers/mach-a3/gpio.c:
+spin_lock_irqrestore(&gpio_lock, flags);

  should that not be "spin_unlock_irqrestore()"?

The code in question was inside an (most often) undefined ifdef.
