identify silicon revision of STM32MP157

[SimonJFisherMB]

Hi,

Is there a way in userspace of (remotely) identifying the silicon revision of an STM32MP157 part? for instance a file or shell command?

thanks

maybe something in here? by the way I'm trying to to figure out if the silicon rev has the reboot/eMMC issue.

cat /proc/cpuinfo
