[PATCH 1/2] m68k/atari: add platform device for Falcon IDE port

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Autoloading of Falcon IDE driver modules requires converting
these drivers to platform drivers.

Add platform device for Falcon IDE interface in Atari platform
setup code in preparation for this.

- define IDE interface address in atari/config.c, create platform device
  always (suggested by Geert Uytterhoeven <geert@xxxxxxxxxxxxxx>)
