README.hardware: update MPC8315E-RDB instructions 

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 a note about dealing with non-default MAC addresses.
Additionally, add a note about ordering MPC8315E-RDBA.

@ -239,30 +239,57 @@ software development of network attached storage (NAS) and digital media server
applications. The MPC8315E-RDB features the PowerQUICC II Pro processor, which
includes a built-in security accelerator.
(Note: you may find it easier to order MPC8315E-RDBA; this appears to be the
same board in an enclosure with accessories. In any case it is fully
compatible with the instructions given here.)
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
Load the kernel and boot it as follows:
--- Preparation ---
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.
Note: if you have altered your board's ethernet MAC address(es) from the
defaults, or you need to do so because you want multiple boards on the same
network, then you will need to change the values in the dts file (patch
linux/arch/powerpc/boot/dts/mpc8315erdb.dts within the kernel source). If
you have left them at the factory default then you shouldn't need to do
anything here.
2. Set up the environment in U-Boot:
--- Booting from NFS root ---
=>setenv ipaddr <board ip>
=>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
Load the kernel and dtb (device tree blob), and boot the system as follows:
3. Download kernel and dtb to boot kernel.
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.
=>tftp 800000 uImage.mpc8315erdb
=>tftp 780000 mpc8315erdb.dtb
=>bootm 800000 - 780000
2. 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
3. Power up or reset the board and press a key on the terminal when prompted
to get to the U-Boot command line
4. Set up the environment in U-Boot:
=> setenv ipaddr <board ip>
=> 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
5. Download the kernel and dtb, and boot:
=> tftp 800000 uImage-mpc8315e-rdb.bin
=> tftp 780000 uImage-mpc8315e-rdb.dtb
=> bootm 800000 - 780000
