Subject: imx: mx6: add display of CPU temperature grade in print_cpuinfo()
X-Git-Url: http://git.dujemihanovic.xyz/?a=commitdiff_plain;h=70caa8e21d3e2393571981631f9b87c253e2ac29;p=u-boot.git

imx: mx6: add display of CPU temperature grade in print_cpuinfo()

When CONFIG_IMX6_THERMAL is defined print the CPU temperature grade info
along with the current temperature.

Before:
 CPU:   Temperature 42 C

After:
 CPU:   Automotive temperature grade (-40C to 125C) at 42C
 CPU:   Industrial temperature grade (-40C to 105C) at 42C
 CPU:   Extended Commercial temperature grade (-20C to 105C) at 42C
