Installation:

Serial Port/TFTP

 1. Setup tftp server on the local network
 2. Connect to UART with TTL
 3. Interupt uboot process with Ctrl-C
 4. Setup appropriate ipaddr and serverip in setenv:
	a) setenv ipaddr 192.168.1.1
	b) setenv serverip 192.168.1.2
 5. On TFTP Server - copy openwrt-ath79-generic-ruckus_r500-initramfs-kernel.bin to /srv/tftp/1600000A.img
 6. On R500 boot into initrd image
	a) tftpboot
	b) bootm
 7. On TFTP server - scp openwrt-ath79-generic-ruckus_r500-squashfs-sysupgrade.bin [email protected]:/tmp
 8. On R500 - sysupgrade /tmp/openwrt-ath79-generic-ruckus_r500-squashfs-sysupgrade.bin

enabling wifi onn start-up

Our hardware supports the R4K FPU, so lets enable it. Without this
option, we are getting 'illegal instruction' errors. Enabling this
allows us to compile software with hardware-float enabled (-mhard-float)
and yields the following results from tst-ieee754 [0]:

Iomega Storcenter ix4-200d is a four-bay SATA NAS powered by a Marvell
Kirkwood SoC clocked at 1.2GHz. It has 512MB of RAM and 32MB of
flash memory, 3x USB 2.0 and 2x 1Gbit/s NIC

Specification:
- SoC: Marvell Kirkwood 88F6281
- CPU/Speed: 1200Mhz
- Flash size: 32 MiB
- RAM: 512MB
- LAN: 2x 1Gbit/s
- 3x USB 2.0

Notes:
- The blue drive LED is triggered by HDD activity, it can not be controlled
  via GPIO.
- The LCD screen requires proprietary code and does not function at this time.
- Due to a kernel-related issue with the Marvell 88SE6121 SATA controller,
  currently only trays numbered #3 and #4 work, #1 and #2 do not. [1]

Switches uarts to 8250_mtk driver, disables uart loopback test at boot,
enables fifo for uart openwrt#3, adds mt7915dan and flow control support to
the btmtkuart driver and derives bluetooth address from system's mac
address. Both uarts need switching because the serial0 alias doesn't
appear to work, and the bluetooth uart gets claimed for the console
when it loads before the generic driver.
