312. Memory Map

332.1. The memory map should look pretty much like this:
34
35     0x0000_0000     0x7fff_ffff     DDR		     2G
36     0x8000_0000     0x9fff_ffff     PCI MEM		     512M
37     0xc000_0000     0xdfff_ffff     Rapid IO		     512M
38     0xe000_0000     0xe00f_ffff     CCSR		     1M
39     0xe200_0000     0xe2ff_ffff     PCI IO		     16M

46
473.1 Explanation of NEW definitions in:
48
49	include/configs/MPC8349ADS.h
50
51    CONFIG_MPC83xx	    MPC83xx family
52    CONFIG_MPC8349	    MPC8349 specific
53    CONFIG_MPC8349ADS	    MPC8349ADS board specific
54    CONFIG_TSEC_ENET	    Use on-chip 10/100/1000 ethernet
55

574. Compilation
58
59    Assuming you're using BASH shell:
60
61	export CROSS_COMPILE=your-cross-compile-prefix
62	cd u-boot
63	make distclean
64	make MPC8349ADS_config
65	make
66
675. Downloading and Flashing Images
68
695.0 Download over serial line using Kermit:
70
71	loadb
72	[Drop to kermit:
73	    ^\c
74	    send <u-boot-bin-image>
75	    c
76	]
77
78
79    Or via tftp:
80
81	tftp 10000 u-boot.bin
82
835.1 Reflash U-boot Image using U-boot
84
85    tftp 10000 u-boot.bin
86    protect off fe000000 fe09ffff
87    erase fe000000 fe09ffff
88
89    cp.b 10000 fe000000 xxxx
90or
91    cp.b 10000 fe000000 a0000
92
93You might have to supply the correct byte count for 'xxxx' from
94the TFTP.  Maybe a0000 will work too, that corresponds to the
95erased sectors.
