[U-Boot] [PATCH 1/3] drivers: block: Kconfig: set default n to CONFIG_DISK

[Mugunthan V N]

When a platform is converted to support DM and when its scsi
driver is not converted to support DM, there is a build break as
multiple definition of scsi_init(). So select CONFIG_DISK only
when the platform supports CONFIG_DISK.

drivers/built-in.o: In function `scsi_init':
/home/mugunthan/workspace/git/work/u-boot/dm-sata/drivers/block/disk-uclass.c:37: multiple definition of `scsi_init'
board/sunxi/built-in.o:/home/mugunthan/workspace/git/work/u-boot/dm-sata/board/sunxi/ahci.c:74: first defined here
Makefile:1171: recipe for target 'u-boot' failed
make: *** [u-boot] Error 1
