+Platform Data
+-------------
+
+  Whenever a device has platform specific data that is specified
+  on a per-machine basis, care should be taken to ensure the
+  following:
+
+    1) that default data is not left in the device to confuse the
+       driver if a machine does not set it at startup
+
+    2) the data should (if possible) be marked as __initdata,
+       to ensure that the data is thrown away if the machine is
+       not the one currently in use.
+
+       The best way of doing this is to make a function that
+       kmalloc()s an area of memory, and copies the __initdata
+       and then sets the relevant device's platform data. Making
+       the function `__init` takes care of ensuring it is discarded
+       with the rest of the initialisation code
+
+       static __init void s3c24xx_xxx_set_platdata(struct xxx_data *pd)
+       {
+           struct s3c2410_xxx_mach_info *npd;
+
+	   npd = kmalloc(sizeof(struct s3c2410_xxx_mach_info), GFP_KERNEL);
+	   if (npd) {
+	      memcpy(npd, pd, sizeof(struct s3c2410_xxx_mach_info));
+	      s3c_device_xxx.dev.platform_data = npd;
+	   } else {
+              printk(KERN_ERR "no memory for xxx platform data\n");
+	   }
+	}
+
+	Note, since the code is marked as __init, it should not be
+	exported outside arch/arm/mach-s3c2410/, or exported to
+	modules via EXPORT_SYMBOL() and related functions.

+ * Theory of operation
+ * -------------------
+ *
+ * This file provides the core code for a forward memory copy used in
+ * the implementation of memcopy(), copy_to_user() and copy_from_user().
+ *
+ * The including file must define the following accessor macros
+ * according to the need of the given function:
+ *
+ * ldr1w ptr reg abort
+ *
+ *	This loads one word from 'ptr', stores it in 'reg' and increments
+ *	'ptr' to the next word. The 'abort' argument is used for fixup tables.
+ *
+ * ldr4w ptr reg1 reg2 reg3 reg4 abort
+ * ldr8w ptr, reg1 reg2 reg3 reg4 reg5 reg6 reg7 reg8 abort
+ *
+ *	This loads four or eight words starting from 'ptr', stores them
+ *	in provided registers and increments 'ptr' past those words.
+ *	The'abort' argument is used for fixup tables.
+ *
+ * ldr1b ptr reg cond abort
+ *
+ *	Similar to ldr1w, but it loads a byte and increments 'ptr' one byte.
+ *	It also must apply the condition code if provided, otherwise the
+ *	"al" condition is assumed by default.
+ *
+ * str1w ptr reg abort
+ * str8w ptr reg1 reg2 reg3 reg4 reg5 reg6 reg7 reg8 abort
+ * str1b ptr reg cond abort
+ *
+ *	Same as their ldr* counterparts, but data is stored to 'ptr' location
+ *	rather than being loaded.
+ *
+ * enter reg1 reg2
+ *
+ *	Preserve the provided registers on the stack plus any additional
+ *	data as needed by the implementation including this code. Called
+ *	upon code entry.
+ *
+ * exit reg1 reg2
+ *
+ *	Restore registers with the values previously saved with the
+ *	'preserv' macro. Called upon code termination.
