Subject: [PATCH] busybox: add posibility to specify correct rtc device for
 hwclock init script
MIME-Version: 1.0
Content-Type: text/plain; charset=utf8
Content-Transfer-Encoding: 8bit

With this patch it's now possible to specify rtc device using HWCLOCKDEVICE
variable in /etc/default/hwclock and the system time is then set using correct
device and vice versa. It's wise to have such functionality, beacuse there're
SBCs with more then one rtc device, for example ts72xx.
