	Recent patches in coreboot have fixed the freeze issues related to the use of me_cleaner on Nehalem. However, at least on the Lenovo X201, with me_cleaner some PCIe devices (like the SATA and USB controllers) disappear. In particular, setting the AltMeDisable bit ("-S" or "-s" flag) makes them disappear completely, while unsetting it makes them disappear only during cold boots. This kind of behaviour was already observed by Youness Alaoui on the Purism Librem laptops ([1]), and it seems related to some required board-specific PCIe configuration in the ME's MFS partition. For this reason, on the Lenovo X201, "-w EFFS" has been added to the me_cleaner arguments, which whitelists the MFS-equivalent partition for ME generation 2. This fixes all the issues, and the PCIe devices work as expected.

2018-04-06	util/me_cleaner: Update to v1.2	Nicola Corna
	Changelog: * Add support for the HAP/AltMeDisable bit * Add support for selective partition removal * Fix the ME permission removal on gen. 3 * Add public key match * Print the compressed size of the Huffman modules on gen. 2 * Wipe the ME6 Ignition firmware images * Fix the removal of the last partition on ME6 * Various region size fixes * Add manpage * Add setup.py * Print the value of the HAP/AltMeDisable bit The output image should be identical, except for the platforms affected by bugs (ME 6.x, but it's not supported by coreboot and ME 11.x with the -d option, but it's not being used in our build process). Overall, nothing should change when it's used with the CONFIG_USE_ME_CLEANER option. Tested on a Lenovo X220 and Sapphire Pure Platinum H61.
