Or maybe imply? 'select' makes it impossible to switch configuration options off. We should only use it if really needed. 'imply' is fine here. Configuration options should appear in *_defconfig files in the same sequence as in the generated .config file. CONFIG_RTC_PL031 precedes CONFIG_SCSI. Please, add a commit message to the next version of the patch.

Basically I don't care whether those two go into defconfig or ARCH_QEMU, but as far as RTC_PL031 is concerned, it always comes with qemu's VM and "selecting" it at ARCH_QEMU is quite reasonable. Turning off this option only saves hundreds of bytes for VM. Who cares? That's said, we will go for 'imply.' For CMD_DATE, it will be automatically turned on if DM_RTC. To make RTC_PL031 independent from CMD_DATE, we also have to modify rtc/date.c's dependency (DM_RTC). > Configuration options should appear in *_defconfig files in the same > sequence as in the generated .config file. CONFIG_RTC_PL031 precedes > CONFIG_SCSI. So they will go away from *_defconfig.
