Re: [parisc-linux] Booting C100

Greg,

The ccio detection via GSC port is really a hack.   I will commit your patch
since we do not have a better way to detect the driver atm :)  Hopefully my
local tree will shape up today, and I can commit a new and improved ccio
driver.  Than I will start working on the I/O tree to eliminate this hack.

Thanks for the patch!

- Ryan
