[poky] [PATCH 2/2] README.hardware: update MPC8315E-RDB instructions

[Paul Eggleton]

Update the instructions for setting up the MPC8315E-RDB so that they are
clearer, use correct filenames, match the other board instructions more
closely, and include details about how to set the MAC address variables
prior to building. Additionally, add notes about ordering MPC8315E-RDBA.

 Setup instructions
 ------------------
 
 You will need the following:
-* nfs root setup on your workstation
-* tftp server installed on your workstation
+* NFS root setup on your workstation
+* TFTP server installed on your workstation
+* Null modem cable connected from your workstation to the first serial port
+  on the board
+* Ethernet connected to the first ethernet port on the board
+
+--- Preparation ---
+
+Prior to building, obtain the ethernet MAC addresses from your MPC8315E-RDB
+system and set them in your build configuration:
+
+ 1. Connect the board's first serial port to your workstation and then start up
+    your favourite serial terminal so that you will be able to interact with
+    the serial console. If you don't have a favourite, picocom is suggested:
+
+  $ picocom /dev/ttyUSB0 -b 115200
+
+ 2. Power up or reset the board and press a key on the terminal when prompted
+    to get to the U-Boot command line
+
+ 3. Type bdinfo, press enter, and look for the ethaddr and eth1addr values
+
+ 4. Edit your local.conf and set MPC8315ERDB_MAC0 and MPC8315ERDB_MAC1 to the
+    ethaddr and eth1addr values (respectively) obtained in the previous step.
+
+Now you can build the desired image as normal. If you already built an image
+before this step you will need to rebuild the kernel (virtual/kernel target)
+before continuing.
+
+--- Booting from NFS root ---
+
+Load the kernel and dtb (device tree blob), and boot the system as follows:
 
-Load the kernel and boot it as follows:
+ 1. Get the kernel (uImage-mpc8315e-rdb.bin) and dtb (uImage-mpc8315e-rdb.dtb)
+    files from the Poky build tmp/deploy directory, and make them available on
+    your TFTP server.
 
- 1. Get the kernel (uImage.mpc8315erdb) and dtb (mpc8315erdb.dtb) files from
-    the Poky build tmp/deploy directory, and make them available on your tftp
-    server.
+ 2. Get access to the U-Boot command line as above
 
- 2. Set up the environment in U-Boot:
+ 3. Set up the environment in U-Boot:

- =>setenv serverip <tftp server ip>
- =>setenv bootargs root=/dev/nfs rw nfsroot=<nfsroot ip>:<rootfs path> ip=<board ip>:<server ip>:<gateway ip>:255.255.255.0:mpc8315e:eth0:off console=ttyS0,115200

- 3. Download kernel and dtb to boot kernel.
+ 4. Download the kernel and dtb, and boot:
 
- =>tftp 800000 uImage.mpc8315erdb
- =>tftp 780000 mpc8315erdb.dtb
- =>bootm 800000 - 780000
+ => tftp 800000 uImage-mpc8315e-rdb.bin
