Subject: qcom_glink_rpm rpm-glink: RPM TOC has invalid magic

Hi linux-arm-msm list,
I can't get cpufreq to work on my IPQ6010 system because glink_rpm_probe()
fails on boot with this message:
[ 2.048522] qcom_glink_rpm rpm-glink: RPM TOC has invalid magic
Dump of the IO area at 0x60000 from U-Boot shows this:

Data in this area changes on every boot. Dump of kernel driver 'buf'
from glink_rpm_parse_toc() shows entirely different data.
Information on version of firmware components that might be relevant:
# cat /proc/device-tree/rpm_version
CRM-RPM.BF.2.4.1-00089
# cat /proc/device-tree/boot_version
crm-ubuntu121-BOOT.XF.0.3-00098-IPQ60xxLZB-1
# cat /proc/device-tree/tz_version
CRM-TZ.WNS.5.1-00127
Any idea?
Thanks,
baruch
