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).
