README.hardware: add Freescale MPC8315E-RDB; other minor tweaks

* Add Freescale MPC8315E-RDB instructions (based on Wind River README passed
  on by Bruce Ashfield)
* Add short info paragraph for RouterStation Pro (to match BeagleBoard)
* Add example for connecting to RouterStation Pro serial console with picocom

+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.
+
+Setup instructions
+------------------
+
+You will need the following:
+* nfs root setup on your workstation
+* tftp server installed on your workstation
+
+The original U-Boot image on board can't boot kernel versions 2.6.34 or later
+successfully, so the U-Boot image should be upgraded to the latest U-Boot.
+
+ 1. First build a new U-Boot image for mpc8315e-rdb, u-boot.bin.mpc8315erdb,
+    then make it available on your tftp server. To compile the new u-boot:
+
+ $ git clone git://git.denx.de/u-boot.git
+ $ cd u-boot
+ $ git checkout -b v2010.09-mpc8315erdb v2010.09
+ $ make ARCH=powerpc CROSS_COMPILE=<powerpc cross compiler path> MPC8315ERDB_config
+ $ make ARCH=powerpc CROSS_COMPILE=<powerpc cross compiler path> all
+ $ cp u-boot.bin u-boot.bin.mpc8315erdb
+
+ 2. Set up the environment in U-Boot:
+
+ =>setenv ipaddr <board ip>
+ =>setenv serverip <tftp server ip>
+
+ 3. Flash the new U-Boot image:
+
+ =>tftp 200000 u-boot.bin.mpc8315erdb
+ =>protect off all
+ =>erase fe000000 +60000
+ =>cp.b 200000 fe000000 60000
+
+Then the kernel can be booted successfully:
+
+ 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. Set up the environment in U-Boot:
+
+ =>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.
+
+ =>tftp 800000 uImage.mpc8315erdb
+ =>tftp 780000 mpc8315erdb.dtb
+ =>bootm 800000 - 780000

 Ubiquiti Networks RouterStation Pro (routerstationpro)
 ======================================================
 
+The RouterStation Pro is an Atheros AR7161 MIPS-based board. Geared towards
+networking applications, it has all of the usual features as well as three
+type IIIA mini-PCI slots and an on-board 3-port 10/100/1000 Ethernet switch,
+in addition to the 10/100/1000 Ethernet WAN port which supports
+Power-over-Ethernet.
