description |
I found that highbank systems (w/o ntpdate setup) always have their system time set to the epoch at boot. The rtc driver for these systems is rtc_pl031. This is currently built as a module, and not included in the initramfs. Looking at the kernel config for other platforms, it appears that this is normally resolved by linking platform rtc drivers in statically.

== SRU Justification [precise] ==
Impact:
* Due to the fact that the rtc_pl031 driver is built as an external module, validation of the last mount time of the root filesystem is not possible and yields the following error:
./drivers/rtc/hctosys.c: unable to open rtc device (rtc0)
Fix:
* This patch statically compiles the rtc-pl031 driver for the highbank kernel flavour and continues to leave it enabled as an external module in omap and armel configs
Testcase:
* Boot highbank based platform without network access or ntp configured with the rtc_pl031 driver compiled statically and note the system time is _not_ set to epoch.
