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:

00060000: 4cc422f6 7ff52c25 c702abe9 7f3f020c    .".L%,........?.

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
