[Avila] GW2201 8 port Serial board linux drivers?

[Mark Kelly]

I figured it out, what turned out to be my problem is that I've been
flashing an old image file to the router.  My binaries automatically
went to my tftp server directory, and as it turns out the file names for
the images got changed in the OpenWrt trunk, and I've been reflashing
one that's a couple of days old over and over.  Not sure who to thank
for that one :)

but these are the options I ended up enabling:

  KCONFIG:= \
        CONFIG_SERIAL_8250_PCI=y\
        CONFIG_SERIAL_8250_NR_UARTS=10\
        CONFIG_SERIAL_8250_RUNTIME_UARTS=10\
        CONFIG_SERIAL_8250_EXTENDED=y\
        CONFIG_SERIAL_8250_SHARE_IRQ=y\
        CONFIG_SERIAL_8250_DETECT_IRQ=y\
        CONFIG_SERIAL_8250_MANY_PORTS=y\
        CONFIG_SERIAL_8250_FOURPORT=y\
        CONFIG_SERIAL_8250_RSA=n

Not sure I need all of those now, as I kept selecting more since it
never seemed to work...


I see this on boot now:
