2019-02-25intelmetool: Use GPLv2+ where possibleDamien Zammit
Upstream intelmetool is out of date; I suggest I archive it instead of trying to merge coreboot's changes into it. However I would like to preserve the licensing of files in the tool as GPLv2+ where possible instead of GPLv2-only.

2017-04-04util/intelmetool: Fix access to deleted data on stackYouness Alaoui
pci_me_interface_scan was returning (via argument 'name') a pointer to the interface name which was stored in a stack variable. This caused part of the name to be printed as garbage stack data in some situations if stack data was overwritten. This moves the name buffer to the calling function so it can be accessed before it gets overwritten.
