From 3ebe59a54111ccc9d4044d73681e93599b5f51fa Mon Sep 17 00:00:00 2001 From: Lukas Bulwahn Date: Wed, 14 Sep 2022 16:27:12 +0200 Subject: [PATCH] ata: clean up how architectures enable PATA_PLATFORM and PATA_OF_PLATFORM There are two options for platform device PATA support: PATA_PLATFORM: Generic platform device PATA support PATA_OF_PLATFORM: OpenFirmware platform device PATA support If an architecture allows the generic platform device PATA support, it shall select HAVE_PATA_PLATFORM. Then, Generic platform device PATA support is available and can be selected. If an architecture has OpenFirmware support, which it indicates by selecting OF, OpenFirmware platform device PATA support is available and can be selected. If OpenFirmware platform device PATA support is selected, then the functionality (code files) from Generic platform device PATA support needs to be integrated in the kernel build for the OpenFirmware platform device PATA support to work. Select PATA_PLATFORM in PATA_OF_PLATFORM to make sure the needed files are added in the build. So, architectures with OpenFirmware support, do not need to additionally select HAVE_PATA_PLATFORM. It is only needed by architecture that want the non-OF pata-platform module. Reflect this way of intended use of config symbols in the ata Kconfig and adjust all architecture definitions. This follows the suggestion from Arnd Bergmann (see Link).
