conf/machine: Remove mpc8315e-rdb machine

Browse Source 
This hardware is old/obsolete and unobtainable. Its proving hard to support
with nobody fixing bugs or helping keep the platform running/up to date.

Whilst there is value in real hardware testing, this platform ist just too
old and obsolete to support. This does leave a gap for the power architecture
but at this point there is nobody willing to step up to cover it.

The TSC did discuss and agree support for this platform should be removed.

It calls into question the support/testing of the architecture by Yocto
Project which is being discussed by the TSC and governing board.

3. Insert the SD card into the Beaglebone and boot the board.
Freescale MPC8315E-RDB (mpc8315e-rdb)
=====================================
The MPC8315 PowerPC reference platform (MPC8315E-RDB) is aimed at hardware and
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
* Straight-thru 9-conductor serial cable (DB9, M/F) connected from your
PC to UART1
* Ethernet connected to the first ethernet port on the board
--- Preparation ---
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.
Note: To boot from USB disk you need u-boot that supports 'ext2load usb'
command. You need to setup TFTP server, load u-boot from there and
flash it to NOR flash.
Beware! Flashing bootloader is potentially dangerous operation that can
brick your device if done incorrectly. Please, make sure you understand
what below commands mean before executing them.
Load the new u-boot.bin from TFTP server to memory address 200000
=> tftp 200000 u-boot.bin
Disable flash protection
=> protect off all
Erase the old u-boot from fe000000 to fe06ffff in NOR flash.
The size is 0x70000 (458752 bytes)
=> erase fe000000 fe06ffff
Copy the new u-boot from address 200000 to fe000000
the size is 0x70000. It has to be greater or equal to u-boot.bin size
=> cp.b 200000 fe000000 70000
Enable flash protection again
=> protect on all
Reset the board
=> reset
--- Booting from USB disk ---
1. Flash partitioned image to the USB disk
# dd if=core-image-minimal-mpc8315e-rdb.wic of=/dev/sdb
2. Plug USB disk into the MPC8315 board
3. 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
4. Power up or reset the board and press a key on the terminal when prompted
to get to the U-Boot command line
5. Optional. Load the u-boot.bin from the USB disk:
=> usb start
=> ext2load usb 0:1 200000 u-boot.bin
and flash it to NOR flash as described above.
6. Load the kernel and dtb from the first partition of the USB disk:
=> usb start
=> ext2load usb 0:1 1000000 uImage
=> ext2load usb 0:1 2000000 dtb
7. Set bootargs and boot up the device
=> setenv bootargs root=/dev/sdb2 rw rootwait console=ttyS0,115200
=> bootm 1000000 - 2000000
--- Booting from NFS root ---
Load the kernel and dtb (device tree blob), and boot the system as follows:
1. Get the kernel (uImage-mpc8315e-rdb.bin) and dtb (uImage-mpc8315e-rdb.dtb)
files from the tmp/deploy directory, and make them available on your TFTP
server.
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 1000000 uImage-mpc8315e-rdb.bin
=> tftp 2000000 uImage-mpc8315e-rdb.dtb
=> bootm 1000000 - 2000000
--- Booting from JFFS2 root ---
1. First boot the board with NFS root.
2. Erase the MTD partition which will be used as root:
$ flash_eraseall /dev/mtd3
3. Copy the JFFS2 image to the MTD partition:
$ flashcp core-image-minimal-mpc8315e-rdb.jffs2 /dev/mtd3
4. Then reboot the board and set up the environment in U-Boot:
=> setenv bootargs root=/dev/mtdblock3 rootfstype=jffs2 console=ttyS0,115200
