Hello,
I am referring specifically to the status line, marking the ti,hwmods entry as disabled will not have any effect here.
The usage of vrtc is determined by the design of your board and which PMIC you have in use, I cannot comment on whether or not you need it. There are other discussions on this forum about vrtc with the TPS65910 which may be able to help you out.
I would recommend building without CONFIG_RTC_HCTOSYS, you can do this with menuconfig under Device Drivers > Real Time Clock > Set system time from RTC on startup and resume. That should prevent that driver from being built in, although that error is a graceful failure and should not have any effect on the system.
The hwclock failure is in userspace and has to do with your rootfs, in the TI rootfs it is run by /etc/init.d/hwclock.sh, so you would need to prevent that.
