41.	Memory Map
5	The memory map looks like this:
6
7	0x0000_0000	0x03ff_ffff	DDR		 64M
8	0x8000_0000	0x8fff_ffff	PCI MEM		 256M
9	0x9000_0000	0x9fff_ffff	PCI_MMIO	 256M
10	0xe000_0000	0xe00f_ffff	IMMR		 1M
11	0xd000_0000	0xd3ff_ffff	PCI IO		 64M
12	0xfe00_0000	0xfeff_ffff	NOR FLASH (CS0)	 16M
13
142.	Compilation
15
16	Assuming you're using BASH (or similar) as your shell:
17
18	export CROSS_COMPILE=your-cross-compiler-prefix-
19	make distclean
20	make MPC8323ERDB_config
21	make
22
233.	Downloading and Flashing Images
24
253.1	Reflash U-Boot Image using U-Boot
26
27	N.b, have an alternate means of programming
28	the flash available if the new U-Boot doesn't boot.
29
30	First try a:
31
32	tftpboot $loadaddr $uboot
33
34	to make sure that the TFTP load will succeed before
35	an erase goes ahead and wipes out your current firmware.
36	Then do a:
37
38	run tftpflash
39
40	which is a shorter version of the manual sequence:
41
42	tftp $loadaddr u-boot.bin
43	protect off fe000000 +$filesize
44	erase fe000000 +$filesize
45	cp.b $loadaddr fe000000 $filesize
46
47	To keep your old U-Boot's environment variables, do a:
48
49	saveenv
50
51	prior to resetting the board.
52
533.2	Downloading and Booting Linux Kernel
54
55	Ensure that all networking-related environment variables are set
56	properly (including ipaddr, serverip, gatewayip (if needed),
57	netmask, ethaddr, eth1addr, rootpath (if using NFS root),
58	fdtfile, and bootfile).
59
60	Then, do one of the following, depending on whether you
61	want an NFS root or a ramdisk root:
62
63	run nfsboot
64
65	or
66
67	run ramboot
68
694	Notes
