Subject: [PATCH v1 0/2] firmware: dmi_scan: Make it work in kexec'ed kernel

Until now DMI information is lost when kexec'ing. Fix this in the same way as
it has been done for ACPI RSDP.

Series has been tested on Galileo Gen2 where DMI is used by drivers, in
particular the default I2C host speed is choosen based on DMI system
information and now gets it correct.

  firmware: dmi_scan: Pass dmi_entry_point to kexec'ed kernel
