+Freescale MPC8323ERDB Board
+-----------------------------------------
+
+1. Memory Map
+ The memory map looks like this:
+
+ 0x0000_0000 0x03ff_ffff DDR 64M
+ 0x8000_0000 0x8fff_ffff PCI MEM 256M
+ 0x9000_0000 0x9fff_ffff PCI_MMIO 256M
+ 0xe000_0000 0xe00f_ffff IMMR 1M
+ 0xd000_0000 0xd3ff_ffff PCI IO 64M
+ 0xfe00_0000 0xfeff_ffff NOR FLASH (CS0) 16M
+
+2. Compilation
+
+ Assuming you're using BASH (or similar) as your shell:
+
+ export CROSS_COMPILE=your-cross-compiler-prefix-
+ make distclean
+ make MPC8323ERDB_config
+ make
+
+3. Downloading and Flashing Images
+
+3.1 Reflash U-boot Image using U-boot
+
+ N.b, have an alternate means of programming
+ the flash available if the new u-boot doesn't boot.
+
+ First try a:
+
+ tftpboot $loadaddr $uboot
+
+ to make sure that the TFTP load will succeed before
+ an erase goes ahead and wipes out your current firmware.
+ Then do a:
+
+ run tftpflash
+
+ which is a shorter version of the manual sequence:
+
+ tftp $loadaddr u-boot.bin
+ protect off fe000000 +$filesize
+ erase fe000000 +$filesize
+ cp.b $loadaddr fe000000 $filesize
+
+ To keep your old u-boot's environment variables, do a:
+
+ saveenv
+
+ prior to resetting the board.
+
+3.2 Downloading and Booting Linux Kernel
+
+ Ensure that all networking-related environment variables are set
+ properly (including ipaddr, serverip, gatewayip (if needed),
+ netmask, ethaddr, eth1addr, rootpath (if using NFS root),
+ fdtfile, and bootfile).
+
+ Then, do one of the following, depending on whether you
+ want an NFS root or a ramdisk root:
+
+ run nfsboot
+
+ or
+
+ run ramboot
+
+4 Notes
+
+ The console baudrate for MPC8323ERDB is 115200bps.
