	+	'''This is a work in progress'''
	+	Explains what to change in order to build the 2.6.31 LF Explorer kernel for Didj. Use your DJHI to boot the zImage from uSD.
	+
	+	1. make lf1000_ts_defconfig
	+
	+	2. edit .config. (we are enabling jffs2 and giving the right bootargs):
	+
	+	<code>
	+
	+	CONFIG_CMDLINE="mem=18M mlc_fb=0x01200000,0x01200000 init=/sbin/init console=ttyS0,115200 root=31:06 ro rootflags=noatime rootfstype=jffs2 ubi.mtd=Brio ubi.mtd=prg_Brio ubi.mtd=Cartridge"
	+
	+	CONFIG_JFFS2_FS=y
	+
	+	</code>
	+
	+	3. edit line 184 of linux2.6/Makefile to point to your cross compiler (or comment it out if you know the varaible is set elsewhere).
	+
	+	4. edit include/asm/mach-types.h (the number has changed to 2028 - but the boot loader only knows about 1235)
	+
	+	(you may need to 'make' once and ctrl-c to get the mach-types file generated the first time.)
	+	<code>
	+
	+	//define MACH_TYPE_ZIR2412 1235
	+
	+	define MACH_TYPE_DIDJ 1235
	+
	+	...
	+
	+	//define MACH_TYPE_DIDJ 2028
	+
	+	</code>
	+
	+	4.1 instead of editig mach-types.h you can edit the file that it is generated from, mach-types (no.h!)
	+	in /linux-2.6/arch/arm/tools, edit the file and look for 2028, copy everything on the line upto 2028:
	+
	+	'''didj MACH_DIDJ DIDJ '''
	+
	+	comment out the 2028 line and now search for 1235 and replace the line with the above, make sure you add 1235 to the end:
	+
	+	'''didj MACH_DIDJ DIDJ 1235'''
	+
	+	This allows you to do 'make clean' without having to re-edit mach-types.h each time, if you also own an explorer you might not want to do this.
	+
	+	5. edit drivers/mtd/nand/lf1000.c (using didj's 9 partition scheme)

	+	#define MLC_MAJOR 251
	+	#define MLC_LAYER_MAJOR 250
	+	This will enable the mlc driver to work with /dev/mlc
