From 83d2aed4440c47acc813abeac4acf4390cb40a8c Mon Sep 17 00:00:00 2001 From: Finn Thain Date: Tue, 15 Jan 2019 15:18:56 +1100 Subject: scsi/atari_scsi: Don't select CONFIG_NVRAM On powerpc, setting CONFIG_NVRAM=n builds a kernel with no NVRAM support. Setting CONFIG_NVRAM=m enables the /dev/nvram misc device module without enabling NVRAM support in drivers. Setting CONFIG_NVRAM=y enables the misc device (built-in) and also enables NVRAM support in drivers. m68k shares the valkyriefb driver with powerpc, and since that driver uses NVRAM, it is affected by CONFIG_ATARI_SCSI, because of the use of "select NVRAM". We can avoid the "select" here, but drivers still have to interpret the CONFIG_NVRAM symbol consistently regardless of platform. In this patch and the subsequent fbdev driver patch, the convention is adopted across all relevant platforms whereby NVRAM functionality gets enabled in a given device driver when the nvram misc device is built-in or when both drivers are modules.
